Spectroscopy from the Hubble space telescope cosmic origins spectrogragh of the southern nova-like BB Doradus in an intermedicate state

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 $0.80\,{M}_{\odot }$($\mathrm{log}(g)=8.4$). The disk, with a mass accretion rate of $\approx {10}^{-10}\,{M}_{\odot }\,{\mathrm{yr}}^{-1}$, contributes about 1/5 to 1/2 of the FUV flux
