Characterisation of the magnetic field of the Herbig Be star HD 200775
E. Alecian, C. Catala, G. A. Wade +9
After our recent discovery of four magnetic Herbig stars, we have decided to study in detail one of them, HD 200775, to determine if its magnetic topology is similar to that of the…
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…
Asteroseismology and Interferometry
M. S. Cunha, C. Aerts, J. Christensen-Dalsgaard +22
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies…
Impact of the new solar abundances on the calibration of the PMS binary system RS Cha
E. Alecian, Y. Lebreton, M-J. Goupil +2
Context: In a recent work, we tried to obtain a calibration of the two components of the pre-main sequence binary system RS Cha by means of theoretical stellar models. We found tha…
Spectropolarimetric observations of the transiting planetary system of the K dwarf HD 189733
C. Moutou, J. -F. Donati, R. Savalle +7
With a Jupiter-mass planet orbiting at a distance of only 0.031 AU, the active K2 dwarf HD 189733 is a potential candidate in which to study the magnetospheric interactions of a co…
