Compact binary mergers are sources of gravitational waves, and can be accompanied with electromagnetic signals. I will discuss the possible features in the kilonova emissions which may help distinguish the black hole – neutron star mergers from the binary neutron stars. Furthermore, the amount of ejected material may depend on whether the system undergoes the creation of a transient hyper-massive, differentially rotating neutron star. In this context, the numerical simulatiosn of post-merger systems and their outflows are important to understand the nature of progenitor systems.
In this talk, I will present a suite of GR MHD simulations performed by our group, to model the neutrino driven disk winds and their contribution to the kilonova emissions.
