Catapaguropsis Lemaitre & McLaughlin 2006
No full textCatapaguropsis Lemaitre & McLaughlin, 2006 (emended) Catapaguropsis Lemaitre & McLaughlin, 2006: 58. Diagnosis. Eleven pairs of biserial phyllobranchiate gills. Rostrum broadly subtriangular or reduced to broadly rounded lobe. Ocular peduncles with very slender penultimate segments, ultimate segments also slen- der proximately, but distally broadened, corneas prominently dilated; ocular acicles quite small, triangular. Antennal peduncles with supernumerary segmentation. Mandible with entirely calcified cutting edge except for small, corneous tooth at outer lower angle. Maxillule with external lobe of endopod rudimentary or vestigial. Maxilla with endopod exceeding distal margin of scaphognathite. First maxilliped with slender endopod exceeding distal margin of basial endite. Second maxilliped without distinguishing characters. Third maxilliped with crista dentata reduced or not, with accessory tooth. Sternite of third maxillipeds (thoracic somite IX of Pilgrim 1973) unarmed. Sternite of chelipeds (thoracic somite X) narrow, incompletely fused to larger sternite of second pereopods. Sternites of second and third pereopods (thoracic somites XI, XII) very broad, with distinct median concavities. Chelipeds long, slender; right appreciably stouter, but not necessarily longer. Ambulatory legs sexually dimorphic or not; dactyls slender or somewhat blade-shaped. Fourth pereopods simple or semichelate, propodal rasp absent or consisting of single row of corneous scales; preungual process well developed. Fifth pereopods minutely chelate. Males with short, stout right sexual tube directed toward exterior; very short left sexual tube or papilla; no paired or unpaired pleopods. Females with paired gonopores; no paired and modified first pleopods, unpaired biramous left pleopods 2–4, pleopod 5 absent. Pleon always reduced posteriorly in males, reduced or not in females. Symmetrical uropods reduced or not. Telson with transverse incisions weak or obsolete; posterior lobes separated by broad median concavity or by minute median cleft, unarmed or with few minute spinules. Type species. Catapaguropsis queenslandica Lemaitre & McLaughlin, 2006, by original designation. Distribution. Queensland, Australia and South China Sea; 296– 388 m. Remarks. The new species, described below, is clearly assignable to Catapaguropsis on the basis of male characters: sexual tube, absence of male pleopods, shape and reduction of the male pleon, symmetrical uropods, which are also markedly reduced in males, but differs from the type species in female characters. Of the similarities with the genus Catapagurus observable in the female of Catapaguropsis queenslandica, which include ambulatory legs with blade-shaped dactyls, ambulatory meri each with one or more subdistal spines on the dorsal surface, and the tendency for loss of the left fifth pleopod, only the latter loss is seen in the female of C. brucei n. sp. In the male of C. queenslandica, as in both sexes of species of Pteropagurus McLaughlin & Rahayu, 2006, the third pereopods are markedly longer than the second. This dimorphism in C. brucei n. sp. is uncertain because only a single second right pereopod remains with the male paratype. Females of both Catapaguropsis species have ambulatory legs of generally equal length. The dimorphism in the fourth pereopods seen in C. queenslandica is not present in C. brucei n. sp.; both sexes have simple propodi, lacking propodal rasps. In Catapaguropsis, as in Pteropagurus, the sternite of the third pereopods is noticeably broadened. This was thought to also be a dimorphic character in Pteropagurus; however, the posterior extension observed in males of P. inermis McLaughlin & Rahayu, 2006 and P. s p i n a McLaughlin & Rahayu, 2006 was found to occur in both sexes in a third recently discovered species (McLaughlin, in press). Certain inaccuracies in the original generic description of the mouthparts of C. queenslandica are corrected based on a reexamination of the female paratype and on the morphology of the new species. The maxillule was illustrated (Lemaitre & McLaughlin 2006: fig. 2 B) as having a bilobed coxal endite; but reexamination of the maxillule has shown this condition to be an artifact. The coxal endite of the the maxillule of C. queenslandica and the new species is represented by a single lobe as is typical for paguroids in general. Similarly, the three-segmented exopods of the second and third maxillipeds (ibid.: fig. 2 E, F) are artifacts; the exopods are two segmented as in most pagurids. The basis and ischium of the third maxilliped were illustrated (ibid.: fig. 2 F) as being completely fused, and the crista dentata was described as lacking an accessory tooth. In the new species, when viewed externally, the basis and ischium similarly appeared to be completely fused, but internally, a suture line was visible. Reexamination has shown this also to be the case for C. queenslandica, indicating the basis and ischium must be considered incompletely fused. The crista dentata in the new species, when viewed externally, consisted of a row of translucent teeth decreasing in size anteriorly, but with one appreciably larger subdistal tooth. However, the internal view of the ischium showed that the crista dentata actually consisted of all small teeth distally and an adjacent subdistal large accessory tooth. The maxillule and second and third maxillipeds of C. queenslandica are herein illustrated accurately (Fig. 2 a–c). The absence of an accessory tooth as a character that will distinguish Catapaguropsis from Catapagurus is not correct. Both genera have an accessory tooth on the crista dentata.Published as part of Mclaughlin, Patsy A. & Lemaitre, Rafael, 2007, A new and distinctive species of the hermit crab genus Catapaguropsis (Crustacea: Decapoda: Anomura: Paguridae) from the South China Sea, pp. 31-41 in Zootaxa 1560 on pages 32-33, DOI: 10.5281/zenodo.17832

The GAPS Programme with HARPS-N at TNG. XIX. Atmospheric Rossiter-McLaughlin effect and improved parameters of KELT-9b
No full textAims. In the framework of the GAPS project, we observed the planet-hosting star KELT-9 (A-type star, v sin i ~ 110 km s−1) with the HARPS-N spectrograph at the Telescopio Nazionale Galileo. In this work we analyse the spectra and the extracted radial velocities to constrain the physical parameters of the system and to detect the planetary atmosphere of KELT-9b.Methods. We extracted the mean stellar line profiles from the high-resolution optical spectra via an analysis based on the least-squares deconvolution technique. Then we computed the stellar radial velocities with a method optimised for fast rotators by fitting the mean stellar line profile with a purely rotational profile instead of using a Gaussian function.Results. The new spectra and analysis led us to update the orbital and physical parameters of the system, improving in particular the value of the planetary mass to Mp = 2.88 ± 0.35 MJup. We discovered an anomalous in-transit radial velocity deviation from the theoretical Rossiter-McLaughlin effect solution, calculated from the projected spin-orbit angle λ = −85.78 ± 0.46 degrees measured with Doppler tomography. We prove that this deviation is caused by the planetary atmosphere of KELT-9b, thus we call this effect Atmospheric Rossiter-McLaughlin effect. By analysing the magnitude of the radial velocity anomaly, we obtained information on the extension of the planetary atmosphere as weighted by the model used to retrieve the stellar mean line profiles, which is up to 1.22 ± 0.02 Rp.Conclusions. The Atmospheric Rossiter-McLaughlin effect will be observable for other exoplanets whose atmosphere has non-negligible correlation with the stellar mask used to retrieve the radial velocities, in particular ultra-hot Jupiters with iron in their atmospheres. The duration and amplitude of the effect will depend not only on the extension of the atmosphere, but also on the in-transit planetary radial velocities and on the projected rotational velocity of the parent star
Can facies act as a chronostratigraphical tool?
No full textRecent advances in chronostratigraphy are enabling global correlation of Silurian strata at a temporal resolution of 10-100 k.y. Comparative analysis of disparate localities at this resolution is yielding surprisingly similar peculiarities of facies. Facies analysis has been traditionally regarded as a tool to investigate local paleoenvironmental conditions and reconstruct past paleoecological settings. Less frequently are aspects of facies recognized as long-distance time-correlative markers. The concept of time-specific facies, originally proposed by Walliser (1986) and recently revised by Brett et al. (2012), challenges the “strictly local” facies paradigm by emphasizing that some aspects of facies are signatures of broader oceanic-climatic processes. Their synchronous occurrence, spanning major portions of sedimentary basins to globally, represents the key distinctive factor of time-specific facies. This aspect is combined with the significance of the ecostratigraphic analysis as a tool to identify bioevents and, therefore, for improving biostratigraphic subdivisions (e.g., Boucot, 1986).
Marine ironstones represent a prime example of time-specific facies. Silurian ironstones retaining microbial signatures are documented by Ferretti et al. (2012) in forms of Fe-rich oolitic horizons and ferruginous laminated structures for the Llandovery-Wenlock boundary interval (mid-late Telychian, Pt. celloni Superzone-Pt. a. amorphognathoides Zone and Sheinwoodian, Oz. s. rhenana Zone) in the Carnic Alps (Austria). Age-equivalent ironstones also occur in the Appalachian Basin of eastern North America (McLaughlin et al., 2012). Appalachian Basin ironstones collected from the New Point Stone quarry (Napoleon, Indiana) and Dawes Quarry Creek (Clinton, New York) were recently analyzed through combined analytical techniques (i.e., confocal laser Raman microscopy, X-ray diffraction, ESEM-EDX, and optical microscopy) for a geobiological characterization. Results demonstrate that the Appalachian ironstones seem to reflect the same microbially-mediated iron mineralization already documented in the Carnic Alps. Combined evidence of iron geochemistry and microbial interactions include i) the formation of planar laminated ironstones (late Telychian); ii) coeval ooidal pack- to grain-ironstones; iii) a wealth of other microbial-related morphostructures and mineralogies. The synchroneity of iron microbe activity on opposite ends of the Iapetus Ocean during the late Telychian and Sheinwoodian is inferred as a time-specific sea water redox signature associated with the Ireviken Event

3D WKB solution for fast magnetoacoustic wave behaviour around an X-line
No full textContext - We study the propagation of a fast magnetoacoustic wave in a 3D magnetic field created from two magnetic dipoles. The magnetic topology contains an X-line.
Aims - We aim to contribute to the overall understanding of MHD wave propagation within inhomogeneous media, specifically around X-lines.
Methods - We investigate the linearised, 3DMHD equations under the assumptions of ideal and cold plasma.We utilise theWKB approximation and Charpit’s method during our investigation.
Results - It is found that the behaviour of the fast magnetoacoustic wave is entirely dictated by the local, inhomogeneous, equilibrium Alfv´en speed profile. All parts of the wave experience refraction during propagation, where the magnitude of the refraction effect depends on the location of an individual wave element within the inhomogeneous magnetic field. The X-line, along which the Alfv´en speed is identically zero, acts as a focus for the refraction effect. There are two main types of wave behaviour: part of the wave is either trapped by the X-line or escapes the system, and there exists a critical starting region around the X-line that divides these two types of behaviour. For the set-up investigated, it is found that 15.5% of the fast wave energy is trapped by the X-line.
Conclusions - We conclude that linear, � = 0 fast magnetoacoustic waves can accumulate along X-lines and thus these will be specific locations of fast wave energy deposition and thus preferential heating. The work here highlights the importance of understanding the magnetic topology of a system. We also demonstrate how the 3D WKB technique described in this paper can be applied to other magnetic configurations
