We present an analysis of Rapid Keck Spectroscopy of the CVs AM Her (polar) and SS Cyg (dwarf nova). We decompose the spectra into constant and variable components and identify different types of variability in AM Her with different characteristic timescales. The variable flickering component of the accretion disc flux md the observational characteristics of a small flare in SS Cyg are isolated.

Resumen

Resumen

Presentamos un análisis de Espectroscopía Rápida de Keck de las CVs AM Her (polar) y SS-Cyg (nova enana). Descomponemos los espectros en componentes constantes y variables e identificamos diferentes tipos de variabilidad en AM Her con diferentes escalas caraeterísticas de tiempo. Se aislaron la componente variable del flujo del disco de acreción y las caraeterísticas observacionales de una peqneña fulguración en SS Cyg.
