Cataclysmic variables.
Abstract
Models of time-dependent, evolving accretion disks are described, and applied to dwarf nova eruptions. The models involve: (1) surface density evolution to a steady state, with mass transfer at 5 x 10 to the 16th g/sec; (2) luminosity change of one disk face, and of spot luminosity plus disk, where the spot luminosity dominates until viscous evolution spreads material down to the white dwarf surface; (3) surface density evolution, with a burst of mass transfer at two million seconds containing 1.2 x 10 to the 24th g; and (4) the variation of disk, spot and boundary layer luminosity during the mass transfer burst.
