1000 cataclysmic variables identified from DESI spectroscopy
K. Inight, B. T. Gänsicke, A. Aungwerojwit +41
Most cataclysmic variables (CVs) are discovered when they have an outburst generating an inherent selection bias against CVs that rarely, or never, outburst. CVs discovered by virt…
A Sibling of AR Scorpii: SDSS J230641.47244055.8 and the Observational Blueprint of White Dwarf Pulsars
N. Castro Segura, I. Pelisoli, B. T. Gänsicke +21
Radio pulsating white dwarf (WD) systems, known as WD pulsars, are non-accreting binary systems where the rapidly spinning WD interacts with a low-mass companion producing pulsed n…
A targeted search for binary white dwarf pulsars using Gaia and WISE
Ingrid Pelisoli, T. R. Marsh, G. Tovmassian +24
After its discovery in 2016, the white dwarf binary AR Scorpii (AR Sco) remained for several years the only white dwarf system to show pulsed radio emission associated with a fast-…
Follow-up on three poorly studied AM CVn stars
Amornrat Aungwerojwit, Boris T. Gaensicke, E. Breedt +12
We report follow-up observations of three poorly studied AM CVn-type binaries: CRTS CSS150211 J091017-200813, NSV1440, and SDSSJ183131.63+420220.2. Analysing time-series photometry…
Long-term photometric monitoring and spectroscopy of the white dwarf pulsar AR Scorpii
Ingrid Pelisoli, T. R. Marsh, S. G. Parsons +14
AR Scorpii (AR Sco) is the only radio-pulsing white dwarf known to date. It shows a broad-band spectrum extending from radio to X-rays whose luminosity cannot be explained by therm…
Optical detection of the rapidly spinning white dwarf in V1460 Her
Ingrid Pelisoli, T. R. Marsh, R. P. Ashley +15
Accreting magnetic white dwarfs offer an opportunity to understand the interplay between spin-up and spin-down torques in binary systems. Monitoring of the white dwarf spin may rev…
BG Tri an example of a low inclination RW Sex-type novalike
M. S. Hernandez, G. Tovmassian, S. Zharikov +4
We analysed a wealth of optical spectroscopic and photometric observations of the bright (V=11.9) cataclysmic variable BG Tri. TheGaiaDR2 parallax gives a distance d=334(8)pc to th…
NGTS and HST insights into the long period modulation in GW Librae
P. Chote, B. T. Gaensicke, J. McCormac +17
Light curves of the accreting white dwarf pulsator GW Librae spanning a 7.5 month period in 2017 were obtained as part of the Next Generation Transit Survey. This data set comprise…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
A Volume Limited Sample of Cataclysmic Variables from DR2: Space Density and Population Properties
A. F. Pala, B. T. Gänsicke, E. Breedt +15
We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the ESA $\mathit{Gaia…
Evidence for mass accretion driven by spiral shocks onto the white dwarf in SDSS J123813.73-033933.0
A. F. Pala, B. T. Gänsicke, T. R. Marsh +21
We present high-time-resolution photometry and phase-resolved spectroscopy of the short-period () cataclysmic variable SDSS J123813.73-033933.…
New Photometric Investigation of the Low-Mass-Ratio Contact Binary Star V1853 Orionis
Jia-Jia He, Sheng-Bang Qian, B. Soonthornthum +3
Four-color charge-coupled device (CCD) light curves in , , and bands of the total-eclipsing binary system, V1853 Ori, are presented. By comparing our light curves w…
The physical properties of AM CVn stars: new insights from Gaia DR2
G. Ramsay, M. J. Green, T. R. Marsh +9
AM CVn binaries are hydrogen deficient compact binaries with an orbital period in the 5-65 min range and are predicted to be strong sources of persistent gravitational wave radiati…
A radio pulsing white dwarf binary star
T. R. Marsh, B. T. Gänsicke, S. Hümmerich +23
White dwarfs are compact stars, similar in size to Earth but ~200,000 times more massive. Isolated white dwarfs emit most of their power from ultraviolet to near-infrared wavelengt…
The Second Data Release of the INT Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS DR2)
