    The spectroscopic evolution of the recurrent nova T Pyxidis during its 2011 outburst (Corrigendum). I. The optically thick phase and the origin of moving lines in novae
    We correct the velocities quoted for interstellar absorption features from Shore et al. (2011), A&A, 533, L8.

    The spectroscopic evolution of the recurrent nova T Pyxidis during its 2011 outburst. I. The optically thick phase and the origin of moving lines in novae
    Aims: We aim to derive the physical properties of the recurrent nova T Pyx and the structure of the ejecta during the early stages of expansion of the 2011...

    The system parameters of the polars MR SER and ST LMi
    We obtain the NaI lambdalambda8183, 8195 absorption-line radial velocity curves for the polars ST LMi and MR Ser, from which we find the semi-amplitudes to be K...

    The Wendelstein Calar Alto Pixellensing Project (WeCAPP): the M 31 nova catalogue
    We present light curves from the novae detected in the long-term, M 31-monitoring WeCAPP project. The goal of WeCAPP is to constrain the compact dark matter...

    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...

    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...
