V471 Tauri
Abstract
K. A. Jensen, Naval Research Laboratory, communicates: "A 28- hr EXOSAT observation of the dA2K0V, 12.5-hr period, detached binary V471 Tau has revealed soft x-ray pulsations from the white dwarf. The pulse period is 554.73 +/- 0.30 s. The pulse profile is double-peaked, suggesting a bipolar structure. The two minima in the pulse profile have intensities of 0.74 and 0.86 with respect to the maximum intensity. A search for evidence of a white dwarf magnetic field is suggested. A search for the pulse period in the optical data base is also suggested."
