Dwarf novae are a type of cataclysmic variable in which one of the components is a white dwarf. Their outbursts can range in brightness from two to five magnitudes at intervals that can vary from days to decades. The purpose of this study is to analyze the outburst of SS Cygni on the nights of June 18-22, 1987. Using an Interactive Reduction Software (IRS) package and a Gaussian fit program, the emission and absorption line strengths on the rise to outburst showed an increase in the flux as well as various other details supported by theory. / Dwarf novae -- Accretion disk -- SS Cygni -- Data analysis and results. / Department of Physics and Astronomy
