On the origin of the close pair of degenerate dwarfs L 870-2.
Abstract
It is proposed that L870-2 is a postalgol binary consisting of two degenerate helium dwarfs. The ratio of the mass components in these systems is limited to the narrow range of 0.87 + or - 0.02, which agrees with the observed value. Precursors of these systems may have been RC Cas and AR Mon.
