Search for neutron star binaries in the Local Group galaxies using LISA.

SETO N.

Abstract (from CDS):

We discuss the prospects of LISA for detecting neutron star binaries (NSBs) in the Local Group galaxies such as LMC and M31. Using the recently estimated merger rate 1540 Gpc–3 yr–1 and inversely applying the conventional arguments based on the B-band galaxy luminosities, we estimate the frequency distributions of NSBs in the local galaxies. We find that, after 10 yr observation with its current design sensitivity, LISA might detect ∼5 NSBs both in LMC and M31 with signal-to-noise ratios larger than 10. Some of the NSBs might be three-dimensionally localized well within LMC. These binaries will be useful for studying various topics including the origin of r-process elements.
