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...
The non-radially pulsating primary of the cataclysmic variable GW Librae
The dwarf nova GW Librae (GW Lib) is the first cataclysmic variable (CV) discovered to have a primary in a white dwarf instability strip, making it the first...
Spectroscopic observations of novae date back a century, and the fundamental nature of the outburst has been understood for 50 years. Yet, recent observations...
We present intermediate resolution spectroscopy of the dwarf nova CY UMa in quiescence. From the radial velocities of the Hα emission, we derive an orbital...
The orbital period of V458 Vulpeculae, a post-double common-envelope nova
We present time-resolved optical spectroscopy of V458 Vulpeculae (Nova Vul 2007 No. 1) spread over a period of 15 months starting 301d after its discovery. Our...
We present our on-going project to unveil the post-nova population by re-discovering old novae that have been lost after the initial outburst and in which the...
The properties of cataclysmic variables in photometric Hα surveys
We report on the properties of 71 known cataclysmic variables (CVs) in photometric Hα emission-line surveys. Our study is motivated by the fact that the Isaac...
The return of the spin period in DW Cnc and evidence of new high state outbursts
DW Cnc is an intermediate polar which has previously been observed in both high and low states. Observations of the high state of DW Cnc have previously...
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.
