The OmegaWhite Survey for Short Period Variable Stars VI. Open Clusters
R. Toma, G. Ramsay, C. S. Jeffery +3
Using light curves with 3 min cadence and a duration of 2 hrs made using the OmegaWhite survey, we present the results of a search for short-period variable stars in the fiel…
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…
The OmegaWhite Survey for Short-Period Variable Stars IV: Discovery of the warm DQ white dwarf OW J175358.85-310728.9
S. A. Macfarlane, P. A. Woudt, P. Dufour +10
We present the discovery and follow-up observations of the second known variable warm DQ white dwarf OW J175358.85-310728.9 (OW J1753-3107). OW J1753-3107 is the brightest of any o…
The OmegaWhite survey for Short-Period Variable Stars III: Follow-up Photometric and Spectroscopic Observations
S. A. Macfarlane, P. A. Woudt, P. J. Groot +10
We present photometric and spectroscopic follow-up observations of short-period variables discovered in the OmegaWhite survey: a wide-field high-cadence g-band synoptic survey targ…
The OmegaWhite Survey for short period variable stars II: An overview of results from the first four years
Ruxandra Toma, Gavin Ramsay, Sally MacFarlane +7
OmegaWhite is a wide-field, high cadence, synoptic survey targeting fields in the southern Galactic plane, with the aim of discovering short period variable stars. Our strategy is…
The OmegaWhite Survey for Short-Period Variable Stars I: Overview and First Results
S. A. Macfarlane, R. Toma, G. Ramsay +5
We present the goals, strategy and first results of the OmegaWhite survey: a wide-field high-cadence -band synoptic survey which aims to unveil the Galactic population of short-…
KIC7668647: a 14 day beaming sdB+WD binary with a pulsating subdwarf
J. H. Telting, A. S. Baran, P. Nemeth +6
The recently discovered subdwarf B (sdB) pulsator KIC7668647 is one of the 18 pulsating sdB stars detected in the Kepler field. It features a rich g-mode frequency spectrum, with a…
High-speed photometry of faint cataclysmic variables - VIII. Targets from the Catalina Real-time Transient Survey
D. L. Coppejans, P. A. Woudt, B. Warner +7
Time series photometry of 20 Cataclysmic Variables detected by the Catalina Real-time Transient Survey is presented. 14 of these systems have not been observed previously and only…
High speed photometry of faint Cataclysmic Variables - VII. Targets selected from the Sloan Digital Sky Survey and the Catalina Real-time Transient Survey
Patrick A. Woudt, Brian Warner, Deanne de Bude +3
We present high speed photometric observations of 20 faint cataclysmic variables, selected from the Sloan Digital Sky Survey and Catalina catalogues. Measurements are given of 15 n…
