AN X-RAY TEST OF WHITE & BECKER'S DISK IN WR 140
ABSTRACT
We request 3 A05 observations of 20ksec each to make a crucial test for the presence in the prototype colliding-wind binary system WR140 of the disk proposed by White and Becker on the basis of their detailed 8-year radio study. The ASCA observations should be scheduled roughly six months apart in every window in which WR140 is visible. We will propose to observe WR140 every six months until the end of the ASCA mission in order to map emitting and absorbing material throughout the orbit.
