X-RAY OBSERVATIONS OF THE ECLIPSING MASSIVE WOLF-RAYET BINARIES
ABSTRACT
We propose the observations of the eclipsing massive Wolf-Rayet binaries CV Ser and CQ Cep. We observe these sources at three different orbital phases: 0(W-R is front), 1/4 and 1/2(O is front). We try to detect the spectra from the thin thermal plasma with a phase-related variable absorption, which is very useful for the establishment of the universal senario of massive W-R binaries. On the basis of this senario, we are going to measure abundances of W-R wind material using the plasma temperature and absorption. We also search the wind accelarating regions near the W-R surface.
