Binary white dwarfs and neutron stars in the transient sky

Oct. 15 - 14:30 - 2020

Speaker Alexey Bobrick (Lund Observatory)

Title: Binary white dwarfs and neutron stars in the transient sky

Recent advances in all-sky synoptic surveys, their rapid spectroscopic follow-up and spectropolarimetry have uncovered a wealth of data about known transients, such as type 1a supernovae, as well as a variety of new classes of transient events. In this talk, I will review the key recent advances in our understanding of type 1a supernovae, both from the observational and modelling side. Additionally, by using white dwarf-neutron star binaries as a show-case, I will demonstrate how we gradually uncover the nature of new types of transients. Vera Rubin observatory, coming operational in the next two years, will dramatically advance this already active field of transient research.
