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…

Magnetic Doppler Imaging of Ap stars

J. Silvester, G. A. Wade, O. Kochukhov +2

Historically, the magnetic field geometries of the chemically peculiar Ap stars were modelled in the context of a simple dipole field. However, with the acquisition of increasingly…

Vertical stratification of iron abundance in atmospheres of blue horizontal-branch stars

V. Khalack, F. LeBlanc, B. B. Behr +2

The observed slow rotation and abundance peculiarities of certain blue horizontal branch (BHB) stars suggests that atomic diffusion can be important in their stellar atmospheres an…

Magnetism in pre-MS intermediate-mass stars and the fossil field hypothesis

E. Alecian, G. A. Wade, C. Catala +11

Today, one of the greatest challenges concerning the Ap/Bp stars is to understand the origin of their slow rotation and their magnetic fields. The favoured hypothesis for the latte…

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…

Magnetism, rotation and accretion in Herbig Ae-Be stars

E. Alecian, G. A. Wade, C. Catala +7

Studies of stellar magnetism at the pre-main sequence phase can provide important new insights into the detailed physics of the late stages of star formation, and into the observed…
