In this poster we present a preliminary model of cataclysmic variables, close binary systems consisting of a white dwarf primary and a lower mass main-sequence secondary star. Mass transfer from the secondary results in the formation of an accretion disk surrounding the primary.
We modeled the accretion disk with the method of smoothed particle hydrodynamics (SPH), as implemented in the public domain code VINE, which we modified for this project. We incorporated VINE's dynamic smoothing lengths and time-varying viscosity to create a more physical model as compared to pre-existing simulations.
This project was funded by a partnership between the National Science Foundation (NSF AST-0552798), Research Experiences for Undergraduates (REU), and the Department of Defense (DoD) ASSURE (Awards to Stimulate and Support Undergraduate Research Experiences) programs.
