Analytical Modeling of Radial Velocity Curves of Hα Emission from WW And

Radial Velocity (RV) plots of emission lines, including H_α, from non-magnetic Cataclysmic Variables (CV), are usually fit with a sin curve. This sin fit sometimes does not prove to be the best fit for some non-magnetic CVs with accretion discs. An analytical model is created based on our 3D Smoothed Particle Hydrodynamic (SPH) numerical code in order to simulate the RV curves. The observational target is WW And, a long period non-magnetic CV. The model takes into account disc ellipticity and inclination angle that provide good non-sinusoidal fits to the observed RV data.
