Why are some A stars magnetic, while most are not?
G. A. Wade, J. Silvester, K. Bale +21
A small fraction of intermediate-mass main sequence (A and B type) stars have strong, organised magnetic fields. The large majority of such stars, however, show no evidence for mag…
Magnetism and rotation in Herbig Ae/Be stars
E. Alecian, G. A. Wade, C. Catala +8
Among the main sequence intermediate mass A and B stars, around 5% host large-scale organized magnetic fields. Most of these stars are very slow rotators compared to their non-magn…
Spectropolarimetry of cool stars
P. Petit
In recent years, the development of spectropolarimetric techniques deeply modified our knowledge of stellar magnetism. In the case of solar-type stars, the challenge is to measure…
Detection of the Molecular Zeeman Effect in Circular Polarization on Cool Active Stars
S. V. Berdyugina, P. Petit, D. M. Fluri +2
We report on the first ever detection of circular polarization in molecular lines forming in magnetic regions on the surfaces of active stars. The new observations were obtained wi…
First Direct Detection of Magnetic Fields in Starspots and Stellar Chromospheres
S. V. Berdyugina, D. M. Fluri, N. Afram +5
Here we report on the first detection of circular polarization in molecular lines formed in cool magnetic regions (starspots) and in chromospheric emission lines formed in hot plag…
Magnetic topologies of cool stars
J. -F. Donati, M. M. Jardine, P. Petit +14
Stellar magnetic fields can be investigated using several, very complementary approaches. While conventional spectroscopy is capable of estimating the average magnetic strength of…
