Seminari


Seminars are organized jointly by the Trieste Astronomical Observatory (INAF/OATS) and the Astronomy Unit of the Physics Dept. of the Trieste University (UNI/TS). They usually take place on Wednesdays at 11:30, in the seminar room (Sala Ovale) of Villa Bazzoni in via Bazzoni 2, TS.

SPEAKER: Alessandro Bressan (SISSA, Trieste, IT)
TITLE: From Stars to Black Holes 

 

ABSTRACT: The recent spectacular direct discovery of gravitational waves with the Advanced LIGO detectors showed that stellar black holes (BH) exist in nature and that, when they are orbiting around each other in a binary system, they may merge in less than the Hubble time.  The masses of the components  measured in the first BH merger event detected were surprisingly large, more than 25 solar masses, and unexpectedly quite discrepant from  the predictions of most theoretical  models.  Clarifying the reasons of this discrepancy is one of the fundamental steps to understand the formation channels and the rates of BH binary mergers. I will review the recent advances in the theory of massive stars with particular focus on those aspects that rendered possible the prediction of the existence of such heavy stellar BHs.
