We have conducted a spectroscopic analysis of the far-ultraviolet archival spectra of four symbiotic variables, EG And, AE Ara, CQ Dra, and RW Hya. RW Hya and EG And have never had a recorded outburst, while CQ Dra and AE Ara have outburst histories. We analyze these systems while they are in quiescence in order to help reveal the physical propert…

Far Ultraviolet Spectroscopy of Old Novae. II. RR Pic, V533 Her, and DI Lac
DOI: 10.3847/1538-3881/153/3/109 Bibcode: 2017AJ....153..109S

The old novae V533 Her (Nova Her 1963), DI Lac (Nova Lac 1910), and RR Pic (Nova Pic 1891) are in (or near) their quiescent stage, following their nova explosions, and continue to accrete at a high rate in the aftermath of their explosions. They exhibit continua that are steeply rising into the FUV, as well as absorption lines and emission lines o…

Hubble COS Spectroscopy of the Dwarf Nova CW Mon: The White Dwarf in Quiescence?
DOI: 10.3847/1538-3881/aa774c Bibcode: 2017AJ....154...48H

Szkody, Paula; Sion, Edward M.; Godon, Patrick +4 more

We present a synthetic spectral analysis of the HST COS spectrum of the U Geminorum-type dwarf nova CW Mon, taken during quiescence as part of our COS survey of accreting white dwarfs (WDs) in Cataclysmic Variables. We use a synthetic photosphere and optically thick accretion disk spectra to model the COS spectrum as well as archival IUE spectra o…
