Two new double-lined spectroscopic binary white dwarfs identified by astronomers

A team of U.S.-Canadian astronomers has conducted radial velocity observations of four binary white dwarf candidates. They report that two of them, designated WD 0311−649 and WD 1606+422, are apparently double-lined spectroscopic binary systems. The finding is detailed in a paper published February 14 on arXiv.org.
