Magnetic topologies of the Herbig Ae/Be stars
E. Alecian, G. A. Wade, C. Catala +9
Our recent discoveries of magnetic fields in a small number of Herbig Ae/Be (HAeBe) stars, the evolutionary progenitors of main sequence A/B stars, raise new questions about the or…
Toroidal versus poloidal magnetic fields in Sun-like stars: a rotation threshold
P. Petit, B. Dintrans, S. K. Solanki +8
From a set of stellar spectropolarimetric observations, we report the detection of surface magnetic fields in a sample of four solar-type stars, namely HD 73350, HD 76151, HD 14623…
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…
The coronal structure of AB Dor determined from contemporaneous Doppler imaging and X-ray spectroscopy
G. A. J. Hussain, M. Jardine, J. -F. Donati +6
We obtain contemporaneous observations of the surface and corona of AB Dor using ground-based circularly polarised spectra from the Anglo-Australian Telescope and X-ray data from t…
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…
