Issue Date: | 2016 | Journal: | THE ASTROPHYSICAL JOURNAL | Number: | 833 | Issue: | 2 | First Page: | 146 | Abstract: | We present a spectral analysis of the spectrum from the Hubble Space Telescope Cosmic Origins Spectrograph (HST/COS) of the southern VY Scl nova-like variable BB Doradus, obtained as part of a Cycle 20 HST/COS survey of accreting white dwarfs (WDs) in cataclysmic variables. BB Dor was observed with COS during an intermediate state with a low mass accretion rate, thereby allowing an estimate of the WD temperature. The results of our spectral analysis show that the WD is a significant far-ultraviolet (FUV) component of the spectrum with a temperature of about 35,000-50,000 K, assuming a WD mass of 0.80 {M}<SUB>☉ </SUB>({log}(g)=8.4). The disk, with a mass accretion rate of ≈ {10}<SUP>-10</SUP> {M}<SUB>☉ </SUB> {{yr}}<SUP>-1</SUP>, contributes about 1/5 to 1/2 of the FUV flux. | URI: | http://hdl.handle.net/20.500.12386/24483 | URL: | https://iopscience.iop.org/article/10.3847/1538-4357/833/2/146 | ISSN: | 0004-637X | DOI: | 10.3847/1538-4357/833/2/146 | Bibcode ADS: | 2016ApJ...833..146G | Fulltext: | open |
