A detailed spectroscopic analysis of the open cluster NGC 5460
L. Fossati, C. P. Folsom, S. Bagnulo +5
Within the context of a large project aimed at studying early F-, A- and late B-type stars we present the abundance analysis of the photospheres of 21 members of the open cluster N…
Is the Wind of the Galactic Oe Star HD 155806 Magnetically Confined?
A. W. Fullerton, V. Petit, S. Bagnulo +2
Spectropolarimetric observations of HD 155806 - the hottest Galactic Oe star - were obtained with CFHT/ESPaDOnS to test the hypothesis that disk signatures in its spectrum are due…
A detailed spectropolarimetric analysis of the planet hosting star WASP-12
L. Fossati, S. Bagnulo, A. Elmasli +9
The knowledge of accurate stellar parameters is paramount in several fields of stellar astrophysics, particularly in the study of extrasolar planets, where often the star is the on…
The rapid rotation and complex magnetic field geometry of Vega
P. Petit, F. Lignières, G. A. Wade +9
The recent discovery of a weak surface magnetic field on the normal intermediate-mass star Vega raises the question of the origin of this magnetism in a class of stars that was not…
