Abstract

When two compact objects such as black holes (BH), white dwarfs (WD), and neutron stars (NS) orbit a common centre of gravity, they emit energy in the form of gravitational waves (GW). The emission of GW will result in the two objects coalescing. In this work, we revisit the coalescence of NS-WD binary systems with the addition of one NS-WD binary system to the coalescing NS-WD binary systems sample. The addition of this new system increased the coalescence rate from previously estimated 4.11⁺₋⁵₂²⁵₅₆ Myr⁻¹ to 8.0⁺₋²⁴_2.0⁰ Myr⁻¹ at the 90% confidence level.
