A study of the effect of rotational mixing on massive stars evolution: surface abundances of Galactic O7-8 giant stars
F. Martins, S. Simon-Diaz, R. H. Barba +2
Massive star evolution remains only partly constrained. In particular, the exact role of rotation has been questioned by puzzling properties of OB stars in the Magellanic Clouds. O…
Inhomogeneous molecular ring around the B[e] supergiant LHA 120-S 73
M. Kraus, L. S. Cidale, M. L. Arias +8
We aim to improve our knowledge on the structure and dynamics of the circumstellar disk of the LMC B[e] supergiant LHA 120-S 73. High-resolution optical and near-IR spectroscopic d…
Discovery of Raman-scattered lines in the massive luminous emission-line star LHA 115-S 18
A. F. Torres, M. Kraus, L. S. Cidale +3
LHA 115-S 18 is a very peculiar emission-line star exhibiting the B[e] phenomenon. Located in the Small Magellanic Cloud, its spectrum shows features of an extremely wide range of…
Bona-fide, strong-variable galactic Luminous Blue Variable stars are fast rotators: detection of a high rotational velocity in HR Carinae
Jose H. Groh, Augusto Damineli, D. John Hillier +6
We report optical observations of the Luminous Blue Variable (LBV) HR Carinae which show that the star has reached a visual minimum phase in 2009. More importantly, we detected abs…
