Observations of Cool-Star Magnetic Fields
Get PDFCool stars like the Sun harbor convection zones capable of producing substantial surface magnetic fields leading to stellar magnetic activity. The influence of stellar parameters like rotation, radius, and age on cool-star magnetism, and the importance of the shear layer between a radiative core and the convective envelope for the generation of magnetic fields are keys for our understanding of low-mass stellar dynamos, the solar dynamo, and also for other large-scale and planetary dynamos. Our observational picture of cool-star magnetic fields has improved tremendously over the last years. Sophisticated methods were developed to search for the subtle effects of magnetism, which are difficult to detect particularly in cool stars. With an emphasis on the assumptions and capabilities of modern methods used to measure magnetism in cool stars, I review the different techniques available for magnetic field measurements. I collect the analyses on cool-star magnetic fields and try to compare results from different methods, and I review empirical evidence that led to our current picture of magnetic fields and their generation in cool stars and brown dwarfs.Deutsche Forschungsgemeinschaft [RE 1664/4-1, RE 1664/9-1
Differential rotation in F stars
No full textDifferential rotation can be detected in single line profiles of stars rotating more rapidly than about v sin i = 10 km s(-1) with the Fourier transform technique. This allows to search for differential rotation in large samples to look for correlations between differential rotation and other stellar parameters. I analyze the fraction of differentially rotating stars as a function of color, rotation, and activity in a large sample of F-type stars. Color and rotation exhibit a correlation with differential rotation in the sense that more stars are rotating differentially in the cooler, less rapidly rotating stars. Effects of rotation and color, however, cannot be disentangled in the underlying sample. No trend with activity is found. (c) 2007 WHEY VCH Verlag GmbH & Co. KGaA, Weinheim
Activity-induced radial velocity jitter in a flaring M dwarf
Get PDFWe investigate the effect of stellar activity and flares on short-term radial velocity measurements in the mid-M flare star CN Leo. Radial velocity variations are calculated from 181 UVES
spectra obtained during three nights. We searched for spectral orders that contain very few atmospheric absorption lines and calibrated them against the telluric A-band from O2 in the
Earth's atmosphere. One giant flare occurred during our observations, which has a very strong effect on radial velocity. The apparent radial velocity shift due to the flare is several hundred m s-1 and clearly correlated with Hα emission. Outside the flare, only spectral orders containing the most prominent emission lines of H, He, and Ca show a correlation to chromospheric activity together with a radial velocity jitter exceeding a few 10 m s-1. We identify a number of spectral orders that are free of strong emission lines and show no flaring-related radial velocity jitter, although flares occurred as strong as 0.4 dex in normalized Hα luminosity. The mean radial velocity jitter due to moderate flaring is less than 10 m s-1. Strong flares are easily recognized directly in the spectra and should be neglected

Tradition oder Plagiat? : die ‚Stilkunst‘ von Ludwig Reiners und die ‚Stilkunst‘ von Eduard Engel im Vergleich
No full textZugl.: Bamberg, Univ., Diss., 2014Ist Ludwig Reiners’ Stilkunst ein Plagiat? Hat er aus Eduard Engels (1851-1938) Stilkunst abgeschrieben? Oder reiht sich Reiners (1896-1957) in eine lange Traditionslinie ein, die dadurch gekennzeichnet ist, dass die Autoren griffige Zitate und schmissige Beispiele von ihren Vorgängern übernehmen, ohne auf die Quelle zu verweisen?
Engels Stilkunst erschien erstmals 1911 – sie erlebte 31. Auflagen. 1933 erteilten die Nationalsozialisten dem Autor – er war jüdischer Herkunft – Publikationsverbot. Reiners war Mitglied der NSDAP. Die Schriftstellerei war sein Hobby; im Hauptberuf war er Kaufmann. Seine Stilkunst erschien 1944 und ist noch heute im Handel erhältlich.
In ihren Sprachratgebern stellen Wustmann, Engel, Reiners und Co. Regeln für einen guten Stil auf. Sie zeigen Unsicherheiten im Sprachgebrauch auf und präsentieren ihren Lesern überzeugend, aber meist ohne wissenschaftliche Argumente eine Lösung. Aufgrund ihres normativen Charakters werden Stilratgeber der Laienlinguistik zugeschrieben.
Das Thema ‚Plagiat‘ hat stets Konjunktur, wenn Personen des öffentlichen Interesses betroffen sind. Der Umgang mit Plagiaten wird kontrovers diskutiert. Stilratgeber konnten sich dieser Diskussion bisher weitgehend entziehen und ihre „Abschreibtradition“ ungehindert pflegen.
Vor diesem Hintergrund wird betrachtet, inwiefern Engel und Reiners ihren Vorgängern verhaftet sind. Zentral ist schließlich die Frage, ob Reiners diese sprachberatende Tradition fortführt oder er die Stilkunst seines Vorgängers Engel ausgeschlachtet hat. Reiners hat einem Spiegel-Artikel von 1956 zufolge über den Umgang mit seinen Quellen gesagt: „Das lasse ich hemmungslos abschreiben. Dafür besitze ich Kinder und Sekretärinnen.“ Bezeichnend ist dieser Ausspruch deshalb, weil in Reiners’ Stilkunst hunderte von Übereinstimmungen mit Engels Werk nachgewiesen werden können. Die Frage, wie viel die nächsten Generationen der Stillehren (z.B. von Wolf Schneider) davon übernommen haben, ist offen.Is Ludwig Reiners’s Stilkunst a case of plagiarism? Did he copy Eduard Engel’s (1851-1938) Stilkunst? Or is Reiners (1896-1957) part of a long tradition of writers characterized by simply adopting catchy quotations and snappy examples of their predecessors without citing their sources?
Originally released in 1911, Engel’s Stilkunst has been published in 31 editions since then. In 1933 the National Socialist regime banned him from publishing his works due to his Jewish background. Reiners was a member of the NSDAP. Writing was his hobby; his regular profession was being a merchant. His Stilkunst was published in 1944 and is still available commercially.
Wustmann, Engel, Reiners and Co. established stylistic rules in their usage guides. They point out linguistic uncertainties and offer their readers solutions in a persuasive way but without scholarly reasoning. Because of their normative character style guides are classified as works of lay linguistics.
The topic "plagiarism" is always popular whenever people of public interest are affected. How to deal with plagiarism is subject to controversial debate. Authors of style guides have been able to avoid this debate for the most part and maintain their "copy-and-paste tradition" unimpeded.
Against this background it has to be considered how much Engel and Reiners adhere to their predecessors. The central question is whether Reiners continues their tradition of language advice or simply exploits the Stilkunst of his predecessor Engel. According to an 1956 article in the magazine Spiegel, Reiners said the following about his sources: "I unashamedly allow copying to be made. This is what I have children and secretaries for." This quote is significant due to the fact that there are hundreds of proven matches between Reiners’s Stilkunst und Engel’s work. The question of how many of these the next generation of style guide authors have adopted, is still to be answered
Ultra‐cool and extra‐vigorous: Rotation and activity in Mand L dwarfs
No full textThe study of rotation and activity in low-mass stars or brown dwarfs of spectral classes M and L has seen enormous progress during the last years. I summarize the results from different works that measured activity, rotation, and sometimes magnetic fields. The generation of magnetic activity seems to be unchanged at the threshold to completely convective stars, i.e. no change in the efficiency of the magnetic dynamos is observed. On the other hand, a sudden change in the strength of rotational braking appears at the threshold mass to full convection, and strong evidence exists for rotational braking weakening with lower mass. A probable explanation is that the field topology changes from dipolar to small scale structure as the objects become fully convective. (c) 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
