Radial Velocity Studies of Close Binary Stars.II

Radial velocity measurements and simple sine-curve fits to the orbital velocity variations are presented for the second set of ten contact binary systems. Eight systems are of the A-type: AH Aur, CK Boo, DK Cyg, UZ Leo, XZ Leo, V839 Oph, GR Vir and NN Vir. V842 Her is the only W-type, while SV Equ appears to be a semi-detached system seen at a low orbital inclination rather than a contact binary. Several of the studied system are prime candidates for complete light and radial-velocity synthesis solutions.
