Journal Article
The UVES Paranal Observatory Project: A Library of High- Resolution Spectra of Stars across the Hertzsprung-Russell Diagram
Journal ArticleDOI
A high-resolution spectropolarimetric survey of Herbig Ae/Be stars – I. Observations and measurements
Evelyne Alecian,Evelyne Alecian,Gregg A. Wade,C. Catala,Jason Grunhut,Jason Grunhut,John D. Landstreet,John D. Landstreet,Stefano Bagnulo,Torsten Böhm,Torsten Böhm,Colin P. Folsom,Stephen C. Marsden,Stephen C. Marsden,Ian A. Waite +14 more
TL;DR: In this article, the analysis of a large survey of Herbig Ae/Be stars in circular spectropolarimetry is described and reported, with the primary aim of searching for magnetic fields in these objects.
Journal ArticleDOI
Weak magnetic fields in Ap/Bp stars : Evidence for a dipole field lower limit and a tentative interpretation of the magnetic dichotomy
Michel Aurière,Gregg A. Wade,J. Silvester,J. Silvester,François Lignières,Stefano Bagnulo,K. Bale,B. Dintrans,Jean-François Donati,C. P. Folsom,Michael Gruberbauer,A. Hui Bon Hoa,S. V. Jeffers,N. Johnson,John D. Landstreet,Agnès Lèbre,T. Lueftinger,Stephen C. Marsden,David Mouillet,S. Naseri,Frédéric Paletou,Pascal Petit,J. Power,F. Rincon,S. Strasser,N. Toque +25 more
TL;DR: In this paper, a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields, was used to explore the weak part of the magnetic field distribution of Ap/bp stars.
Journal ArticleDOI
Stellar Spectropolarimetry with Retarder Waveplate and Beam Splitter Devices
Stefano Bagnulo,Marco Landolfi,John D. Landstreet,E. Landi Degl'Innocenti,Luca Fossati,Michael Sterzik +5 more
TL;DR: In this article, the authors define a self-consistent framework starting from the basic definitions of the Stokes parameters, and present an analytical description of the data reduction techniques commonly used with a polarimeter (consisting of a retarder wave plate and a Wollaston prism).
Journal ArticleDOI
