Post-outburst evolution of bonafide FUor V2493 Cyg: A Spectro-photometric monitoring
Arpan Ghosh, Saurabh Sharma, Joe P. Ninan +11
We present here the results of eight years of our near-simultaneous optical/near-infrared spectro-photometric monitoring of bonafide FUor candidate `V2493 Cyg' starting from 2013 S…
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…
Hunting For Eclipses: High Speed Observations of Cataclysmic Variables
Liam K Hardy, Martin J McAllister, Vik S Dhillon +12
We present new time-resolved photometry of 74 cataclysmic variables (CVs), 47 of which are eclipsing. 13 of these eclipsing systems are newly discovered. For all 47 eclipsing syste…
The HU Aqr planetary system hypothesis revisited
K. Gozdziewski, A. Slowikowska, D. Dimitrov +11
We study the mid-egress eclipse timing data gathered for the cataclysmic binary HU Aquarii during the years 1993-2014. The (O-C) residuals were previously attributed to a single ~7…
The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1
S. P. Littlefair, S. L. Casewell, S. G. Parsons +14
We present high time resolution SDSS- and SDSS- light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near…
ULTRASPEC: a high-speed imaging photometer on the 2.4-m Thai National Telescope
V. S. Dhillon, T. R. Marsh, D. C. Atkinson +18
ULTRASPEC is a high-speed imaging photometer mounted permanently at one of the Nasmyth focii of the 2.4-m Thai National Telescope (TNT) on Doi Inthanon, Thailand's highest mountain…
