Double O-Ne-Mg white dwarfs merging as the source of the Powerfull Gravitational Waves for LIGO/VIRGO type interferometers

TL;DR

This paper proposes that mergers of double O-Ne-Mg white dwarfs can generate strong gravitational waves detectable by LIGO/VIRGO, potentially leading to Type Ia supernovae.

Contribution

It introduces a new gravitational wave source model involving O-Ne-Mg white dwarf mergers as a detectable event for current interferometers.

Findings

White dwarf mergers produce gravitational waves in hundreds of Hz range.

Such mergers can be precursors to Type Ia supernovae.

The proposed source is detectable by existing GW observatories.

Abstract

New strong non-spiralling-in gravitational wave (GW) source for LIGO/VIRGO detectors are proposed. Double O-Ne-Mg white dwarf mergers can produce strong gravitational waves with frequencies in the several hundreds Hz range. Such events can be followed by a Super Nova type Ia.
