Scientific paper

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.
