6. Abstract

Non-magnetic cataclysmic variables are important, nearby examples of the accretion
disk phenomenon. In the high or outburst state, their FUV spectra are due primarily
to a disk continuum modified by scattering in a rotating bi-conical outflow. Here,
we propose to advance our understanding of kinematic and ionization structure of CV
winds by performing a detailed analysis of archival FUV spectra of 11 disk-dominated
CVs observed in the high state with HST. We will use a state-of-the-art Monte Carlo
radiative transfer program to produce detailed simulations of all of the features of
the wind. This is needed to determine basic parameters of the flow, such as mass-
loss rate and collimation, and to explore physical questions, such as the underlying
wind-driving mechanism and the effect of the wind on the disk. By studying multiple
systems viewed at different inclination angles, we will attempt to generalize the
results to produce a "standard model" for the winds of CVs.
