A study of the effect of rotational mixing on massive stars evolution: Surface abundances of Galactic O7-8 giant stars
(EDP Sciences, 2017-03)
Context. 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. Aims. Our goal is to study the ...
Discovery of the first B[e] supergiants in M 31
(Iop Publishing, 2014-01)
B[e] supergiants (B[e]SGs) are transitional objects in the post-main sequence evolution of massive stars. The small number of B[e]SGs known so far in the Galaxy and the Magellanic Clouds indicates that this evolutionary ...
The eclipsing LMC star OGLE05155332-6925581: a clue to understand Double Periodic Variables
(Wiley Blackwell Publishing, Inc, 2008-12)
We investigate the nature of OGLE05155332-6925581, one of the brightest members of the enigmatic group of double periodic variables (DPVs) recently found in the Magellanic Clouds. The modelling of archival orbital light ...
