ASASSN-14dx: A cataclysmic variable harbouring a massive pulsating white dwarf
Pasi Hakala, Ingrid Pelisoli, Boris T. Gaensicke +5
We present the results of our study of ASASSN-14dx, a previously known but poorly characterised cataclysmic variable (CV). The source was observed as part of an ongoing high-time-r…
The DBL Survey I: discovery of 34 double-lined double white dwarf binaries
James Munday, Ingrid Pelisoli, P. E. Tremblay +8
We present the first discoveries of the double-lined double white dwarf (DBL) survey that targets over-luminous sources with respect to the canonical white dwarf cooling sequence a…
Doppler Tomography as a tool for characterising exoplanet atmospheres II: an analysis of HD 179949 b
S. M. Matthews, C. A. Watson, E. J. W. de Mooij +5
High-resolution Doppler spectroscopy provides an avenue to study the atmosphere of both transiting and non-transiting planets. This powerful method has also yielded some of the mos…
Long-term variability in debris transiting white dwarfs
Amornrat Aungwerojwit, Boris T. Gaensicke, Vikram S. Dhillon +7
Combining archival photometric observations from multiple large-area surveys spanning the past 17 years, we detect long-term variability in the light curves of ZTFJ032833.52-121945…
Discovery of a Gamma-ray Black Widow Pulsar by GPU-accelerated Einstein@Home
L. Nieder, C. J. Clark, D. Kandel +39
We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi Large Area Telescope g…
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…
High-speed photometry of the disintegrating planetesimals at WD1145+017: evidence for rapid dynamical evolution
B. T. Gaensicke, A. Aungwerojwit, T. R. Marsh +11
We obtained high-speed photometry of the disintegrating planetesimals orbiting the white dwarf WD1145+017, spanning a period of four weeks. The light curves show a dramatic evoluti…
A Spitzer Space Telescope Study of the Debris Disks around four SDSS White Dwarfs
Carolyn Brinkworth, Boris Gaensicke, Jon Girven +4
We present Spitzer Space Telescope data of four isolated white dwarfs that were previously known to harbor circumstellar gaseous disks. IRAC photometry shows a significant infrared…
Double white dwarfs and LISA
T. R. Marsh
Close pairs of white dwarfs are potential progenitors of Type~Ia supernovae and they are common, with of order 100 -- 300 million in the Galaxy. As such they will be significant, p…
