Non-degenerate stars of essentially all spectral classes are soft X-ray sources. Their X-ray
spectra have been important in constraining physical processes that heat plasma in stellar …

We review the current state of knowledge of magnetic fields inside stars, concentrating on
recent developments concerning magnetic fields in stably stratified (zones of) stars, leaving …

Abstract Herbig Ae/Be stars (HAeBes) span a key mass range that links low-and high-mass
stars, and thus provide an ideal window from which to explore their formation. This paper …

We report the discovery of a medium-strength (∼ 0.5 kG) magnetic field on the young,
massive star τ Sco (B0. 2 V), which becomes the third-hottest magnetic star known …

This is the first in a series of papers in which we describe and report the analysis of a large
survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and …

Context. The photospheres of about 5–10% of the upper main sequence stars exhibit
remarkable chemical anomalies. Many of these chemically peculiar (CP) stars have a global …

Context. The evolution of magnetic fields in Ap stars during the main sequence phase is
presently mostly unconstrained by observation because of the difficulty of assigning …

ESPaDOnS is the new-generation stellar spectro-polarimeter designed and built at the
Observatoire Midi-Pyrénées. It is now installed at the Canada-France-Hawaii Telescope …

Context. During the last decade, the FORS1 instrument of the ESO Very Large Telescope
has been extensively used to study stellar magnetism. A number of interesting discoveries of …

Variability in emission lines is a characteristic feature in young stars and can be used as a
tool to study the physics of the accretion process. Here, we present a study of Hα variability …
