X-Ray Pulsars
Abstract
F. Makino and the Ginga Team, Institute of Space and Astronautical Science, Tokyo, reports: "Ginga observed several x-ray pulsars during Mar.-June. The heliocentric pulse periods in seconds (with the uncertainty in parentheses in units of the last decimal place shown) are provided for the objects and dates indicated. With the exception of that for Vela X-1, the quoted pulse periods have been corrected for Doppler effects due to the orbital motion of the pulsar: GX 1+4, Mar. 30.8, 110.233 (3); SMC X-1, May 27.0, 0.710551 (5); Vela X-1, June 8.651, 283.13 (1); X2259+586, June 22.3, 6.978760 (5); Cen X-3, June 22.4, 4.8230 (2)."
