资源简介：
Two independent studies have detected short-period optical variability in the Wolf-Rayet star WR 66. The optical period P = 3.5-4.1 hr is too short to be explained by the stars rotation. The most likely causes are stellar pulsations or a close companion openParpossibly a BH or NSclosePar orbiting deep in the WR wind. We propose to obtain the first pointed X-ray observation of WR 66. Its X-ray spectral and timing properties will allow us to place it into context with other WR stars and may shed light on its unusual variability.
