Title: GRMHD simulations of Magnetised Accretion Induced Collapse of White Dwarfs

Place: DAA Seminar. Jeroni Muñoz Research Building, fourth floor, in Campus de Burjassot.

Day: Thursday, maig 23, 2024.

Hora: 14:30.

Abstract:

Studies have proposed accretion-induced collapse (AIC) of white dwarfs (WDs) as possible power engines of short GRBs with extended emission (sGRB+EE).
Aware of the recent turmoil around GRB211211A (a known sGRB+EE) origins, we revisited the science case of AICs.
In this talk, we present axisymmetric GRMHD + moment-based neutrino transport simulations of magnetised WDs that collapse due to electron capture.
A careful characterization of the multi-messenger emission of these events will be discussed.
In particular, we will discuss the properties of the mass ejection will be discussed.
Also, the gravitational wave emissions and neutrino radiations from the system will be discussed.
