PublicationV533 Herculis: the second SW Sex old nova displaying emission-line flaring
We present high-time-resolution spectroscopy of the non-eclipsing old nova V533 Herculis (N Her 1963). It is the second nova remnant affected by the `SW Sex...

PublicationVery 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...

PublicationWhen 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)...
