Descripción
In this work we analyze time-resolved spectra of SS Cygni in quiescence.
The geometrical and orbital fundamental parameters of the system are
determined. When in the data the contribution of the secondary star is
removed some weak emission lines and a Fe I absorption line become
clearly visible. We detect strong emission from the secondary star due
to being heated by irradiation from the inner regions of the disk.
Evidence for non-keplerian regions in the accretion disk is also found.
