Most double degenerate low-mass white dwarf binaries merge.

BROWN W.R., KILIC M., KENYON S.J. and GIANNINAS A.

Abstract (from CDS):

We estimate the merger rate of double degenerate binaries containing extremely low mass (ELM; \lt 0.3 M☉) white dwarfs (WDs) in the Galaxy. Such WDs are detectable for timescales of 0.1-1 Gyr in the ELM Survey; the binaries they reside in have gravitational wave merger times of 0.001-100 Gyr. To explain the observed distribution requires that most ELM WD binary progenitors detach from the common envelope phase with M☉ WDs.
