Discovery of starspots on Vega - First spectroscopic detection of surface structures on a normal A-type star
T. Böhm, M. Holschneider, F. Lignières +8
The theoretically studied impact of rapid rotation on stellar evolution needs to be confronted with the results of high resolution spectroscopy-velocimetry observations. A weak sur…
A search for Vega-like fields in OB stars
C. Neiner, C. P. Folsom, A. Blazere
Very weak magnetic fields (with a longitudinal component below 1 Gauss) have recently been discovered in the A star Vega as well as in a few Am stars. According to fossil field sce…
Ultra weak magnetic fields in Am stars: Beta UMa and theta Leo
Aurore Blazère, Pascal Petit, François Lignières +3
An extremely weak circularly-polarized signature was recently discovered in spectral lines of the chemically peculiar Am star Sirius A (Petit et al. 2011). This signal was interpre…
The magnetic field of Ori A
A. Blazère, C. Neiner, J-C. Bouret +2
Magnetic fields play a significant role in the evolution of massive stars. About 7% of massive stars are found to be magnetic at a level detectable with current instrumentation and…
