PublicationThe HU Aqr planetary system hypothesis revisited
We study the mid-egress eclipse timing data gathered for the cataclysmic binary HU Aquarii during the years 1993-2014. The (O-C) residuals were previously...

PublicationThe intermediate polar cataclysmic variable GK Persei 120 years after the nova explosion: a first dynamical mass study
We present a dynamical study of the intermediate polar and dwarf nova cataclysmic variable GK Persei (Nova Persei 1901) based on a multisite optical...

PublicationThe January 2015 outburst of a red nova in M 31
Context. M31N 2015-01a (or M31LRN 2015) is a red nova that erupted in January 2015 - the first event of this kind observed in M 31 since 1988. Very few similar...

PublicationThe K-band spectrum of the cataclysmic variable RXJ 0502.8+1624 (Tau 4)
We present the K-band spectrum of the cataclysmic variable RXJ 0502.8+1624 (Tau 4). The spectrum shows a broad, smooth hump, with no absorption lines from the...

PublicationThe Li I resonance line in the spectra of X-ray nova accretion discs
We study the formation of the Li I lambda 6708 Angstroms resonance doublet in spectra of X-ray novae during the stage of outburst decay. We discuss the general...

PublicationThe magnetic SW Sextantis star RXJ1643.7+3402
We present time-resolved spectroscopy and circular spectropolarimetry of the SW Sex star RXJ1643.7+3402. We find significant polarization levels exhibiting a...

PublicationThe massive white dwarf in the recurrent nova TCrB
We have obtained I-, J-, H- and K-band light curves of the recurrent nova TCrB. We find that we can fit the J-band light curve only with a Roche lobe filling...

PublicationThe mysterious eruption of V838 Mon
V838 Mon is marking one of the most mysterious stellar outbursts on record. The spectral energy distribution of the progenitor resembles an under-luminous F...
