Abstract:
In the new era of gravitational wave (GW) and multi-messenger
astrophysics, the detection of a GW signal from the coalescence of a
black hole - neutron star (BHNS) binary remains a highly anticipated
discovery. This kind of system is expected to be within reach of the
second generation of ground-based detectors. In this context, we
develop a series of versatile semi-analytical models to predict the
properties of all the electromagnetic (EM) counterparts of BHNS
mergers.We include the nuclear-decay-powered kilonova emission, its
radio remnant, the prompt emission from the jet and the related
afterglow. The properties of these counterparts depend upon those of
the outflows that result from the partial disruption of the NS during
the merger and from the accretion disc around the remnant, which are
necessary ingredients for transient EM emission to accompany the GW
signal. We therefore define ways to relate the properties of these
outflows to those of the progenitor binary, establishing a link
between the binary parameters and the counterpart properties. From the
resulting model, we anticipate the variety of light curves that can
emerge after a BHNS coalescence, from the radio up to gamma-rays.
These light curves feature universal traits which are the imprint of
the dynamics of the emitting outflows, but at the same time they show
a clear dependence on the BH mass and spin, though with a high degree
of degeneracy. The latter can be deduced by joint GW - EM analysis. In
this paper, we perform a proof-of-concept multi-messenger parameter
estimation of a BHNS merger with an associated kilonova, to test how
the information from the EM counterpart can complement that from the
GW signal. Our results indicate that the observation and modeling of
the kilonova can help to break the degeneracies in the GW parameter
space, leading to better constraints on, e.g., the BH spin.
Description:
We built a composite model to describe the complex electromagnetic
signal that accompanies the tidal (partial) disruption of a NS during
its inspiral and plunge across the horizon of a stellar black hole.
We presented a suite of light curves obtained varying the black hole
mass (MBH) and spin (XBH) (lightcurves in panels a-h of Figure 6),
one at a time, to show the variety in the prospected emission from
these coalescences.
