    The cataclysmic variable SS Cygni
    A general panorama of SS Cygni is presented. The paper first describes the CV cataclysmic variables and the current theories which attempt to describe their...

    The donor star radial velocity curve in the cataclysmic variable GY Cnc confirms white dwarf eclipse modelling mass
    A large number of white dwarf and donor masses in cataclysmic variables have been found via modelling the primary eclipse, a method that relies on untested...

    The evolutionary status of Cataclysmic Variables: eclipse modelling of 15 systems
    We present measurements of the component masses in 15 Cataclysmic Variables (CVs) - 6 new estimates and 9 improved estimates. We provide new calibrations of the...

    The mass of the white dwarf in YY Dra (=DO Dra): Dynamical measurement and comparative study with X-ray estimates
    We present a dynamical study of the intermediate polar cataclysmic variable YY Dra based on time-series observations in the K band, where the donor star is...

    TIC 378898110: A bright, short-period AM CVn binary in TESS
    AM CVn-type systems are ultracompact, helium-accreting binary systems that are evolutionarily linked to the progenitors of thermonuclear supernovae and are...

    Time-resolved optical spectroscopy of IR GEM in quiescence
    Spectroscopic observations of the dwarf nova IR Gem in the range 4000-7000 A, covering a whole orbital period, are presented. The dates of the observations...

    Ultracool Subdwarfs: The Halo Population Down to the Substellar Limit
    Ultracool subdwarfs are low luminosity, late-type M and L dwarfs that exhibit spectroscopic indications of subsolar metallicity and halo kinematics. Their...

    Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag
    The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can...

    V838 Mon and the new class of stars erupting into cool supergiants (SECS)
    V838 Mon has undergone one of the most mysterious stellar outbursts on record. The spectrum at maximum closely resembled a cool AGB star, evolving toward cooler...
