摘要:Abstract I will briefly review the dependence of the explosive yields on the initial mass, metallicity and initial rotational velocity.

摘要:Abstract We examine some debated points in current discussions about rotating stars: the shape, the gravity darkening, the critical velocities, the mass loss rates, the hydrodynamical instabilities, the internal mixing and N–enrichments. The study of rotational mixing requir...

摘要:Abstract I summarize current state-of-the-art methods for treating the difficult problem of turbulent convection in stellar interiors and I discuss a powerful approach for analysis that allows one to leverage the most from 3D stellar models.

摘要:Abstract We review potential mass-loss mechanisms in the various evolutionary stages of massive stars, from the well-known line-driven winds of O-stars and BA-supergiants to the less-understood winds of Red Supergiants. We discuss optically thick winds from Wolf-Rayet stars and V...

摘要:Abstract The recent detection in archival HST images of an object at the the location of supernova (SN) iPTF13bvn may represent the first direct evidence of the progenitor of a Type Ib SN. The object's photometry was found to be compatible with a Wolf-Rayet pre-SN star mass ...

摘要:Abstract In the race to break the SMC frontier and reach metallicity conditions closer to the First Stars the information from UV spectroscopy is usually overlooked. New HST-COS observations of OB stars in the metal-poor galaxy IC1613, with oxygen content ~1/10 solar, have p...

摘要:Abstract Recent stellar evolution computations indicate that massive stars in the range ~ 20-30 M are located in the blue supergiant (BSG) region of the Hertzsprung-Russell diagram at two different stages of their life: immediately after the main sequence (MS, g...

摘要:Abstract Very massive stars (in excess of ~ 100 M ) and massive stars in pre-SN phases at the end of their evolution are continuously approaching the Eddington limit. According to our theoretical predictions their high Eddington factors lead to a peculiar sub-pho...

摘要:Abstract Thorne-Żytkow objects (TŻOs) are a theoretical class of star in which a compact neutron star is surrounded by a large, diffuse envelope. Supergiant TŻOs are predicted to be almost identical in appearance to red supergiants (RSGs), with their very red colors and cool...
