title = "On the frequency of helium-rich degenerates in wide binaries",
author = "Sion, {Edward M.} and Oswalt, {Terry D.}",
note = "The kinematics and spectroscopic properties of the proper motion-selected sample of spectroscopically confirmed white dwarfs which are members of wide binaries are investigated. Kinematically, both samples are dominated by young disk and old disk motions. There exists a possible paucity of halo members, but little difference exists between the composition subgroups except for a possible slight increase in hydrogen-dominated (DA) degenerates at lower tangential velocity.",
