Differential rotation on both components of the pre main-sequence binary system HD 155555
N. J. Dunstone, G. A. J. Hussain, A. Collier Cameron +5
We present the first measurements of surface differential rotation on a pre-main sequence binary system. Using intensity (Stokes I) and circularly polarised (Stokes V) timeseries s…
The first magnetic maps of a pre-main sequence binary star system - HD 155555
N. J. Dunstone, G. A. J. Hussain, A. Collier Cameron +5
We present the first maps of the surface magnetic fields of a pre-main sequence binary system. Spectropolarimetric observations of the young, 18 Myr, HD 155555 (V824 Ara, G5IV + K0…
Magnetism in Herbig Ae/Be stars and the link to the Ap/Bp stars
E. Alecian, C. Catala, G. A. Wade +11
Among the A/B stars, about 5% host large-scale organised magnetic fields. These magnetic stars show also abundance anomalies in their spectra, and are therefore called the magnetic…
Magnetospheric accretion on the T Tauri star BP Tauri
J. F. Donati, M. M. Jardine, S. G. Gregory +15
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisati…
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 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…
