Abstract
The Exosat satellite observed E1405 - 451 in the X-ray band in March 1984 during a high state; and simultaneous UV, optical, and IR coverage was obtained with IUE and from ESO telescopes. The low-energy X-ray curve exhibits a minimum at phase zero which is similar to the optical one, with some indication of temperature modulation with orbital phase. On the contrary, the medium-energy X-ray curve exhibits a broad minimum at phase zero, and the column density varies with phase, which may account for the entire modulation of the intensity.
