Spectro-photometric follow up of the outbursting AM CVn system ASASSN-21br

Autor: Painter, S., Aydi, E., Motsoaledi, M., Sokolovsky, K. V., Strader, J., Buckley, D. A. H., Kochanek, C. S., Maccarone, T. J., Mukai, K., Shappee, B. J., Stanek, K. Z.

We report on spectroscopic and photometric observations of the AM CVn system ASASSN-21br, which was discovered in outburst by the All-Sky Automated Survey for Supernovae in February 2021. The outburst lasted for around three weeks, and exhibited a pr

The OmegaWhite Survey for Short-Period Variable Stars VII: High amplitude, short period blue variables

Autor: Ramsay, G., Woudt, P. A., Kupfer, T., van Roestel, J., Patterson, K., Warner, B., Buckley, D. A. H., Groot, P. J., Heber, U., Irrgang, A., Jeffery, C. S., Motsoaledi, M., Schwartz, M. J., Wevers, T.

Blue Large Amplitude Pulsators (BLAPs) are a relatively new class of blue variable stars showing periodic variations in their light curves with periods shorter than a few tens of mins and amplitudes of more than ten percent. We report nine blue varia

High-speed photometry of faint cataclysmic variables - IX. Targets from multiple transient surveys

Autor: Paterson, K., Woudt, P. A., Warner, B., Breytenbach, H., Gilligan, C. K., Motsoaledi, M., Thorstensen, J. R., Worters, H. L.

We present high-speed photometric observations of 25 cataclysmic variables detected by the All Sky Automated Search for Super-Novae (ASAS-SN), the Mobile Astronomical System of the TElescope-Robot (MASTER) and the Catalina Real-Time Transient Survey

Discovery, observations and modelling of a new eclipsing polar: MASTER OT J061451.70-272535.5

Autor: Breytenbach, H., Buckley, D. A. H., Hakala, P., Thorstensen, J. R., Kniazev, A. Y., Motsoaledi, M., Woudt, P. A., Potter, S. B., Lipunov, V., Gorbovskoy, E., Balanutsa, P., Tyurina, N.

We report the discovery of a new eclipsing polar, MASTER OT J061451.70-272535.5, detected as an optical transient by MASTER auto-detection software at the recently commissioned MASTER-SAAO telescope. Time resolved (10-20 s) photometry with the SAAO 1

Optical Studies of 15 Hard X-ray Selected Cataclysmic Binaries

Autor: Halpern, J. P., Thorstensen, J. R., Cho, P., Collver, G., Motsoaledi, M., Breytenbach, H., Buckley, D. A. H., Woudt, P. A.

We conducted time-resolved optical spectroscopy and/or time-series photometry of 15 cataclysmic binaries that were discovered in hard X-ray surveys by the Swift Burst Alert Telescope (BAT) and the International Gamma-Ray Astrophysics Laboratory (INTE

The OmegaWhite survey for Short-Period Variable Stars III: Follow-up Photometric and Spectroscopic Observations

Autor: Macfarlane, S. A., Woudt, P. A., Groot, P. J., Ramsay, G., Toma, R., Motsoaledi, M., Crause, L. A., Gilbank, D. G., O'Donoghue, D., Potter, S. B., Sickafoose, A. A., van Gend, C., Worters, H. L.

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 targeting the Galactic Plane. We have used fast photometry on the SAAO 1.0
