Gravitational waves from first star remnants
Speaker: Tomoya Kinugawa (Shinshu University)
Abstract:
We calculated binary evolutions of first stars (Pop III) and showed that the typical chirp mass of Pop III binary black holes is ∼30Msun with a total mass of ∼60Msun and the maximum mass of Pop III BBH is more massive than the limit mass of the pair-instability supernovae.
Our result, which predicted gravitational wave events like GW150914 and GW190521, can explain the origin of massive stellar binary black hole mergers.
In this talk, I will explain Pop III binary evolutions and the properties of Pop III binary black hole mergers.
There is a good chance to check indirectly the existence of Pop III massive stars by gravitational waves.
