The white dwarf binary pathways survey - XI. The Gaia-GALEX UV Excess Sample for systems within 350 pc
James A. Garbutt, S. G. Parsons, N. Gentile Fusillo +9
White dwarfs (WDs) with F, G or K type binary companions are the last common ancestor to a zoo of exotic phenomena. Finding a clean sample of such systems is difficult, as WDs in s…
Constraints on an optical counterpart for the long-period radio transient GPM J1839-10
Ingrid Pelisoli, A. J. Brown, N. Castro Segura +14
Long period radio transients (LPTs) are periodic radio sources showing pulsed emission on timescales from minutes to hours. The underlying sources behind this emission are currentl…
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…
Asteroseismology of WD J004917.14-252556.81, the Most Massive Pulsating White Dwarf
O. Caliskan, M. Uzundag, M. Kilic +10
We present extensive follow-up time-series photometry of WD J00492525, the most massive pulsating white dwarf currently known with and $\log{\i…
A magnitude-limited catalogue of unresolved white dwarf-main sequence binaries from Gaia DR3
Alberto Rebassa-Mansergas, Enrique Solano, Alex J. Brown +6
Binary stars containing a white dwarf and a main-sequence star, WDMS binaries, can be used to study a wide range of aspects of stellar astrophysics. We build a magnitude-limited sa…
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-…
Reconstructing post-common envelope white dwarf+main sequence binary histories through inverse population synthesis techniques
Santiago Torres, Marta Gili, Alberto Rebassa-Mansergas +3
The evolution of binary stellar systems involves a wide range of physical processes, many of which are not yet well understood. We aim to build a general-purpose algorithm based on…
A gravitational wave detectable candidate Type Ia supernova progenitor
Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37
Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…
The white dwarf binary pathways survey -- X. Gaia orbits for known UV excess binaries
J. A. Garbutt, S. G. Parsons, O. Toloza +9
White dwarfs with a F, G or K type companion represent the last common ancestor for a plethora of exotic systems throughout the galaxy, though to this point very few of them have b…
A Survey for Radio Emission from White Dwarfs in the VLA Sky Survey
Ingrid Pelisoli, Laura Chomiuk, Jay Strader +22
Radio emission has been detected from tens of white dwarfs, in particular in accreting systems. Additionally, radio emission has been predicted as a possible outcome of a planetary…
The Gaia DR1 Mass-Radius Relation for White Dwarfs
P. -E. Tremblay, N. Gentile-Fusillo, R. Raddi +8
The Gaia Data Release 1 (DR1) sample of white dwarf parallaxes is presented, including 6 directly observed degenerates and 46 white dwarfs in wide binaries. This data set is combin…
The shortest period detached white dwarf + main-sequence binary
S. G. Parsons, T. R. Marsh, B. T. Gänsicke +8
We present high-speed ULTRACAM and SOFI photometry and X-shooter spectroscopy of the recently discovered 94 minute orbital period eclipsing white dwarf / main-sequence binary SDSS…
