Fast spectrophotometry of WD 1145+017
P. Izquierdo, P. Rodríguez-Gil, B. T. Gänsicke +16
WD 1145+017 is currently the only white dwarf known to exhibit periodic transits of planetary debris as well as absorption lines from circumstellar gas. We present the first simult…
VLA Radio Observations of AR Sco
E. R. Stanway, T. R. Marsh, P. Chote +3
AR Scorpii is unique amongst known white dwarf binaries in showing powerful pulsations extending to radio frequencies. Here we aim to investigate the multi-frequency radio emission…
The sdB pulsating star V391 Peg and its putative giant planet revisited after 13 years of time-series photometric data
R. Silvotti, S. Schuh, S. -L. Kim +10
V391 Peg (alias HS2201+2610) is a subdwarf B (sdB) pulsating star that shows both p- and g-modes. By studying the arrival times of the p-mode maxima and minima through the O-C meth…
The OmegaWhite survey for short-period variable stars - V. Discovery of an ultracompact hot subdwarf binary with a compact companion in a 44 minute orbit
T. Kupfer, G. Ramsay, J. van Roestel +20
We report the discovery of the ultracompact hot subdwarf (sdOB) binary OW J074106.0-294811.0 with an orbital period of P min, making it the…
Effective Temperatures of Cataclysmic Variable White Dwarfs as a Probe of their Evolution
A. F. Pala, B. T. Gänsicke, D. Townsley +29
We present HST spectroscopy for 45 cataclysmic variables (CVs), observed with HST/COS and HST/STIS. For 36 CVs, the white dwarf is recognisable through its broad Ly absorption p…
Another one grinds the dust: Variability of the planetary debris disc at the white dwarf SDSS J104341.53+085558.2
Christopher J. Manser, Boris T. Gaensicke, Detlev Koester +2
We report nine years of optical spectroscopy of the metal-polluted white dwarf SDSS J104341.53+085558.2, which presents morphological variations of the line profiles of the 8600 Å…
