gr8stars II : judgement day for spectroscopic parameter model systematics
Alix Violet Freckelton, Annelies Mortier, Megan Bedell +18
Many areas of astrophysics, including exoplanetary studies, rely on precise and accurate stellar parameters. This demands that uncertainties on these parameters truly reflect all b…
Roche tomography of cataclysmic variables - VII. The long-term magnetic activity of AE Aqr
C. A. Hill, C. A. Watson, D. Steeghs +2
We present a long-term study of the secondary star in the cataclysmic variable AE~Aqr, using Roche tomography to indirectly image starspots on the stellar surface spanning 8~years…
The crowded magnetosphere of the post common envelope binary QS Virginis
S. G. Parsons, C. A. Hill, T. R. Marsh +8
We present high speed photometry and high resolution spectroscopy of the eclipsing post common envelope binary QS Virginis (QS Vir). Our UVES spectra span multiple orbits over more…
CI Aql: a Type Ia supernova progenitor?
Dave Sahman, Vik Dhillon, Tom Marsh +4
If recurrent novae are progenitors of Type Ia supernovae, their white dwarfs must have masses close to the Chandrasekhar limit. The most reliable means of determining white dwarf m…
GD 552: a cataclysmic variable with a brown dwarf companion?
E. Unda-Sanzana, T. R. Marsh, B. T. Gansicke +7
GD 552 is a high proper motion star with the strong, double-peaked emission lines characteristic of the dwarf nova class of cataclysmic variable star, and yet no outburst has been…
SDSS J150722.30+523039.8: a CV formed directly from a detached white dwarf/brown dwarf binary?
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +3
We present high-speed, three-colour photometry of the eclipsing cataclysmic variable SDSS J150722.30+523039.8 (hereafter SDSS J1507). This system has an orbital period of 66.61 min…
