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…
Using Gaussian processes to model light curves in the presence of flickering: the eclipsing cataclysmic variable ASASSN-14ag
M. J. McAllister, S. P. Littlefair, V. S. Dhillon +10
The majority of cataclysmic variable (CV) stars contain a stochastic noise component in their light curves, commonly referred to as flickering. This can significantly affect the mo…
Evidence of asymmetries in the Aldebaran photosphere from multi-wavelength lunar occultations
A. Richichi, V. Dyachenko, A. K. Pandey +6
We have recorded three lunar occultations of Aldebaran (AlfTau) at different telescopes and using various band-passes, from the ultraviolet to the far red. The data have been analy…
The hot Gamma-Doradus and Maia stars
L. A. Balona, C. A. Engelbrecht, Yogesh C. Joshi +8
The hot ~Doradus stars have multiple low frequencies characteristic of ~Dor or SPB variables, but are located between the red edge of the SPB and the blue edge of the ~Dor…
Long-term eclipse timing of white dwarf binaries: an observational hint of a magnetic mechanism at work
M. C. P. Bours, T. R. Marsh, S. G. Parsons +18
We present a long-term programme for timing the eclipses of white dwarfs in close binaries to measure apparent and/or real variations in their orbital periods. Our programme includ…
Structural studies of eight bright rimmed clouds in the southern hemisphere
Saurabh Sharma, A. K. Pandey, J. Borissova +7
We carried out deep and wide-field near- and mid-infrared observations for a sample of 8 bright-rimmed clouds (BRCs). Supplemented with the archival data, we have identif…
Long-period variations in the radial velocity of spectroscopic binary m giant mu ursae majoris
Byeong-Cheol Lee, Inwoo Han, Myeong-Gu Park +4
We report that the spectroscopic binary ? Ursae Majoris (?mu UMa) has secondary RV variations of 471.2 days in addition to those of 230.0 days already known. Keplerian orbit analys…
