Ultra-short-period (USP) planets are defined as planets with orbital periods shorter than one day. This type of planets is rare, highly irradiated, and interesting because their formation history is unknown. Aims. We aim to obtain precise mass and radius measurements to confirm the planetary nature of a USP candidate found by the Transiting Exoplanet Survey Satellite (TESS). These parameters can provide insights into the bulk composition of the planet candidate and help to place constraints on its formation history. Methods. We used TESS light curves and HARPS-N spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate found around the star HD 20329 (TOI-4524). We performed a joint fit of the light curves and radial velocity time series to measure the mass, radius, and orbital parameters of the candidate. Results. We confirm and characterize HD 20329b, a USP planet transiting a solar-type star. The host star (HD 20329, V = 8.74 mag, J = 7.5 mag) is characterized by its G5 spectral type with M∗ = 0.90 ± 0.05 M⊙, R∗ = 1.13 ± 0.02 R⊙, and Teff = 5596 ± 50 K; it is located at a distance d = 63.68 ± 0.29 pc. By jointly fitting the available TESS transit light curves and follow-up radial velocity measurements, we find an orbital period of 0.9261 ± (0.5 ×10-4) days, a planetary radius of 1.72 ± 0.07 R∗, and a mass of 7.42 ± 1.09 M∗, implying a mean density of ρp = 8.06 ± 1.53 g cm-3. HD 20329b joins the ~30 currently known USP planets with radius and Doppler mass measurements. © F.

Hints of auroral and magnetospheric polarized radio emission from the scallop-shell star 2MASS J05082729–2101444
No full textScallop-shell stars, a recently discovered class of young M dwarfs, show complex optical light curves that are characterized by periodic dips as well as other features that are stable over tens to hundreds of rotation cycles. The origin of these features is not well-understood. 2MASS J05082729−2101444 is a ∼25 Myr old scallop-shell star that was identified using TESS data; it has a photometric period of 6.73 h that has been attributed to rotation. Of the ∼50 recently confirmed scallop-shell stars, it is one of the few detected at radio frequencies between 1 and 8 GHz. We observed this rare system with the upgraded Giant Meterwave Radio Telescope at 575–720 MHz, covering 88% of the photometric period in each of the two observations scheduled almost a month apart in 2023. We detected approximately millijansky emission from the target in both epochs, with a significant circular polarization fraction: | V / I |∼20 − 50%. The 3.5-minute phase-folded light curves show unique variability in circular polarization. We detected an approximately hour-long helicity reversal during both epochs, and the reversals had similar amplitudes, lengths, and (possibly) occured at similar phases. These results suggest two emission components: The first is a persistent, moderately polarized component possibly ascribable to gyro-synchrotron emission driven by centrifugal breakout events. The second is a highly polarized, short burst-like component that is likely due to an electron cyclotron maser (ECM); it is indicative of auroral emission and is potentially responsible for the helicity reversal. To explain this, we discuss the different origins of the plasma responsible for the radio emission, including the possibility that the occulting material is acting as a plasma source. Future coordinated multifrequency radio and optical observations can further constrain the underlying scenario, as well as the magnetic geometry of the system, if we assume an ECM-like auroral emission
Gliese 12 b: A Temperate Earth-sized Planet at 12 pc Ideal for Atmospheric Transmission Spectroscopy
No full textAbstract Recent discoveries of Earth-sized planets transiting nearby M dwarfs have made it possible to characterize the atmospheres of terrestrial planets via follow-up spectroscopic observations. However, the number of such planets receiving low insolation is still small, limiting our ability to understand the diversity of the atmospheric composition and climates of temperate terrestrial planets. We report the discovery of an Earth-sized planet transiting the nearby (12 pc) inactive M3.0 dwarf Gliese 12 (TOI-6251) with an orbital period ( P orb ) of 12.76 days. The planet, Gliese 12 b, was initially identified as a candidate with an ambiguous P orb from TESS data. We confirmed the transit signal and P orb using ground-based photometry with MuSCAT2 and MuSCAT3, and validated the planetary nature of the signal using high-resolution images from Gemini/NIRI and Keck/NIRC2 as well as radial velocity (RV) measurements from the InfraRed Doppler instrument on the Subaru 8.2 m telescope and from CARMENES on the CAHA 3.5 m telescope. X-ray observations with XMM-Newton showed the host star is inactive, with an X-ray-to-bolometric luminosity ratio of log L X / L bol ≈ − 5.7 . Joint analysis of the light curves and RV measurements revealed that Gliese 12 b has a radius of 0.96 ± 0.05 R ⊕ , a 3 σ mass upper limit of 3.9 M ⊕ , and an equilibrium temperature of 315 ± 6 K assuming zero albedo. The transmission spectroscopy metric (TSM) value of Gliese 12 b is close to the TSM values of the TRAPPIST-1 planets, adding Gliese 12 b to the small list of potentially terrestrial, temperate planets amenable to atmospheric characterization with JWST.MEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ JST ∣ Precursory Research for Embryonic Science and TechnologyMEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ Japan Society for the Promotion of ScienceMEXT ∣ JST ∣ Core Research for Evolutional Science and TechnologyMEC ∣ Agencia Estatal de InvestigaciónMEC ∣ Agencia Estatal de InvestigaciónMEC ∣ Agencia Estatal de Investigaciónthe European Union and State Agency of Innvestigation of the Spanish Ministry of Science and Inovationthe Centre of Excellence ``Severo Ochoa' and ``Maria de Maeztu' awardthe Centre of Excellence ``Severo Ochoa' and ``Maria de Maeztu' awardMassachusetts Institute of Technology http://dx.doi.org/10.13039/100006919NASA ∣ Academic Mission ServiceMargarita Salas Fellowship from the Spanish Ministry of Universitiesthe EU Next Generation fundsItalian National Institute of AstrophysicsSwedish National Space Agency http://dx.doi.org/10.13039/501100001859Swedish Research Council http://dx.doi.org/10.13039/501100004359Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659NASA NExSSMEC ∣ Agencia Estatal de InvestigaciónMEC ∣ Agencia Estatal de InvestigaciónMEC ∣ Agencia Estatal de InvestigaciónMOST ∣ National Natural Science Foundation of ChinaMOST ∣ National Natural Science Foundation of ChinaNAOJ Research Coordination Committee, NIN

OAB symptoms, IPSS, and PVR were recorded before and after 12 weeks of treatment. Participants were stratified by Q max (group A C15 ml/s, group B \15 ml/s) and CT vs. MT. Safety parameters were monitored. Results A total of 2,219 men participated and were involved in safety analysis; 1,849 men (mean age 66 years) fulfilled the inclusion criteria and were involved in efficacy analysis. In group A, 291 men received MT and 479 CT; in group B, 184 men received MT and 895 CT. OAB symptoms improved significantly in all groups throughout the study without differences between MT and CT. IPSS improvement in group B was less with MT than with CT (-3.9 vs. -5.2; P \ 0.001), whereas IPSS improvement was similar in group A (-4.6 vs. -5.1). Mean PVR change was not clinically relevant, but two men (0.1%) experienced urinary retention. Conclusions Under real-life conditions, treatment of OAB symptoms with propiverine ER is equally effective in men with MT or CT regardless of baseline Q max . In men with reduced Q max , IPSS improvement is significantly smaller with MT. The incidence of urinary retention during propiverine ER treatment is low. Keyword
Evaluación de los parámetros de desempeño de un motor generador acoplado a un gasificador de lecho fijo con y sin intercambio de calor, para la obtención de energía eléctrica en la zona de aprovechamiento del Jardín Botánico de la cuidad de Bogotá
No full textLa situación que vive actualmente el mundo ha llevado a la búsqueda de nuevas posibles fuentes energía, en las cuales se de uso a todos aquellos residuos generados en procesos industriales, agrícolas, agroindustriales, entre otros. Por tal razón se ha dado uso a los residuos vegetales ya que estos constituyen la biomasa más abundante del planeta [16]. Los residuos vegetales constituyen la biomasa predominante del planeta, más de 1011 toneladas de estos residuos son producidos en la biósfera.[47]
Teniendo en cuenta que para el país es un avance en cuestión de energías alternativas aprovechar estos recursos, se hace necesario mejorar los problemas que se presentan en el proceso de obtención de energía limpia con la implementación de Biomasa, sabiendo que es una fuente potencial para contribuir al medio ambiente y darle uso a estos recursos [10].
Esta problemática se presenta en la zona de aprovechamiento del Jardín Botánico José Celestino Mutís de la ciudad de Bogotá donde se lleva a cabo el proceso de obtención de energía, mediante la gasificación de un tipo de biomasa compuesta por madera de pino, caucho y acacias, en este proceso no se está generando la energía deseada de 18 kW. Esto se ve reflejado en la potencia y el torque del motor generador, los cuales se encuentran por debajo de lo esperado, generando deficiencias en el proceso de generación.
Por estos motivos en la siguiente investigación deseamos mejorar la eficiencia en el proceso de obtención de energía, se pretende solventar este problema acoplando un intercambiador de calor, el cual por medio de la condensación de alquitranes mejoraría las condiciones de óptimas en el motor generador, y así entregar más energía
