Doubling of minute-long Quasi-Periodic Pulsations from super-flares on a low mass star
J. Gerry Doyle, Puji Irawati, Dmitrii Y. Kolotkov +5
Using the ULTRASPEC instrument mounted on the 2.4-m Thai National Telescope, we observed two large flares, each with a total energy close to 10^34 erg with sub-second cadence. A co…
The post-common-envelope binary central star of the planetary nebula Ou 5: a doubly-eclipsing post-red-giant-branch system
David Jones, James Munday, Romano Corradi +10
We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou~5. Low-resolution spectra obtained duri…
ASAS J071404+7004.3 -- a close, bright nova-like cataclysmic variable with gusty winds
keith Inight, Boris Gaensicke, Dominic Blondel +11
Despite being bright () and nearby ( pc) ASAS J071404+7004.3 has only recently been identified as a nova-like cataclysmic variable. We present time-resolved optical sp…
A 15.7-Minute AM CVn Binary Discovered in K2
M. J. Green, J. J. Hermes, T. R. Marsh +14
We present the discovery of SDSS J135154.46-064309.0, a short-period variable observed using 30-minute cadence photometry in K2 Campaign 6. Follow-up spectroscopy and high-speed ph…
PTF1 J082340.04+081936.5: A hot subdwarf B star with a low mass white dwarf companion in an 87 minute orbit
Thomas Kupfer, Jan van Roestel, Jared Brooks +19
We present the discovery of the hot subdwarf B star (sdB) binary PTF1 J082340.04+081936.5. The system has an orbital period P min (0.060761584(10) days), ma…
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…
