Scientific paper

High velocity winds are common among cataclysmic variables stars (CVs) with luminous accretion disks. What was learned about these winds from IUE spectrophotometry is summarized. The IUE discovered that under some conditions CVs exhibit high-velocity winds. These close binary systems can potentially offer much information about the driving mechanisms of winds in general because: (1) the orbital elements of many of these binaries and their geometry is well understood, allowing the spectral line profiles to be, studied as a function of inclination and stellar mass; and (2) changes in the luminosity of these stars are dramatic and, in some cases, fairly predictable, so that the effect on the winds of changes in the radiation field can be studied.
