Description
The observation of gravitational and electromagnetic waves from a
binary neutron star merger in August 2017 conveyed key information on the
nature of matter at supranuclear densities, on the origin of short-gamma
ray burst, on the production site of of heavy elements via r-process
nucleosynthesis, and on cosmography.
Thus, multimessenger observations of compact binary mergers hold the
promise to unprecedent insights on some of the most fundamental
physics questions.
A crucial and necessary ingredient to intepret such observations is
the precise knowledge of the dynamics of the sources.
I will talk about recent developments on the modeling of neutron star
mergers using numerical simulations in general relativity.
I will focus on the numerical exploration of the the merger remnant and
mass ejecta and their dependence on the binary
parameters. I will discuss detailed models of the gravitational waves and
kilonova light curves, highlighting the prospect of using them in
joint analysis of multimessenger data.
