Compact binary mergers: an astrophysical perspective
S. Rosswog
TL;DR
This paper reviews astrophysical aspects of compact binary mergers, focusing on neutron star systems, their role in enriching galaxies, and their connection to short gamma-ray bursts and electromagnetic signals.
Contribution
It provides a comprehensive overview of the astrophysical processes and implications of neutron star mergers, complementing existing numerical relativity studies.
Findings
Neutron star mergers contribute to neutron-rich matter in galaxies.
They are linked to short gamma-ray bursts.
Electromagnetic signals accompany these mergers.
Abstract
This paper reviews the current understanding of double neutron star and neutron star black hole binaries. It addresses mainly (nuclear) astrophysics aspects of compact binary mergers and thus complements recent reviews that have emphasized the numerical relativity viewpoint. In particular, the paper discusses different channels to release neutron-rich matter into the host galaxy, connections between compact binary mergers and short Gamma-ray bursts and accompanying electromagnetic signals.
