The ELM survey. VII. Orbital properties of low-mass white dwarf binaries.

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

Abstract (from CDS):

We present the discovery of 15 extremely low-mass (5 < log g < 7) white dwarf (WD) candidates, 9 of which are in ultra-compact double-degenerate binaries. Our targeted extremely low-mass Survey sample now includes 76 binaries. The sample has a lognormal distribution of orbital periods with a median period of 5.4 hr. The velocity amplitudes imply that the binary companions have a normal distribution of mass with 0.76 M☉ mean and 0.25 M☉dispersion. Thus extremely low-mass WDs are found in binaries with a typical mass ratio of 1:4. Statistically speaking, 95% of the WD binaries have a total mass below the Chandrasekhar mass, and thus are not type Ia supernova progenitors. Yet half of the observed binaries will merge in less than 6 Gyr due to gravitational wave radiation; probable outcomes include single massive WDs and stable mass transfer AM CVn binaries.
