    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...

    Very high-energy γ-ray observations of novae and dwarf novae with the MAGIC telescopes
    Context. In the last five years the Fermi Large Area Telescope (LAT) instrument detected GeV γ-ray emission from five novae. The GeV emission can be interpreted...

    VLT/FORS spectroscopy of faint cataclysmic variables discovered by the Sloan Digital Sky Survey
    We present medium-resolution VLT/FORS2 spectroscopy of six cataclysmic variables (CVs) discovered by the Sloan Digital Sky Survey (SDSS). We determine orbital...

    When the disc's away, the stars will play: dynamical masses in the nova-like variable KR Aur with a pinch of accretion
    We obtained time-resolved optical photometry and spectroscopy of the nova-like variable KR Aurigae in the low state. The spectrum reveals a DAB white dwarf (WD)...
