Spectroscopy of HD 153919 (= 2U 1700-37)
- 1. Dominion Astrophysical Observatory, Victoria, British Columbia (Canada)
Description
Radial velocities of He II 4541 (absorption) and He II 4686 (emission) in the O6f star HD 153919 confirm the star as the occulting body of the X-ray source 2U 1700–37 with the period 3.412 days (1973). A large scatter may be due to the X-ray source passing through the atmosphere of the primary. The mass of the secondary is estimated to be 2.4 |$M_\odot$| on the assumption of 35 |$M_\odot$| for the primary.
