Emission line tomography of the short period cataclysmic variables CC Scl and V2051 Oph
We present time series spectroscopy of two short period cataclysmic variables, CC Scl and V2051 Oph, to test the efficiency of Doppler-tomography-based methods in constraining orbital parameters of evolved cataclysmic variables. We find that the Ca ii triplet lines offer superior diagnostics, revealing emission components from the mass donors and …
