Scaling Up: A Global Optical/X-ray Correlation For Reprocessing Across Black Hole Masses
Changhyun Cho, David M. Russell, Aaryan Sharma +9
This study extends the optical/X-ray correlation from black hole low-mass X-ray binaries (XRBs) to active galactic nuclei (AGN), bridging scales from stellar-mass to supermassive b…
Discovering Cataclysmic Variables from the Rubin Observatory LSST
D. A. H. Buckley, Y. Tampo, P. Szkody +8
The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will provide a windfall of new transients and variable sources. Here we have performed mock observation simul…
Spectro-photometric follow up of the outbursting AM CVn system ASASSN-21br
S. Painter, E. Aydi, M. Motsoaledi +8
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 Februar…
The OmegaWhite Survey for Short-Period Variable Stars VII: High amplitude, short period blue variables
G. Ramsay, P. A. Woudt, T. Kupfer +11
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 m…
Optical Studies of Ten Hard X-ray Selected Cataclysmic Binaries
J. P. Halpern, J. R. Thorstensen
We conducted time-resolved optical spectroscopy and/or photometry of ten cataclysmic binaries that were discovered in hard X-ray surveys, with the goal of measuring their orbital p…
Optical Studies of 8 AM Herculis-Type Cataclysmic Variable Stars
John R. Thorstensen, Mokhine Motsoaledi, David A. H. Buckley +2
We report detailed follow-up observations of 8 cataclysmic variable stars (CVs) that are apparently AM Her stars, also called polars. For all, we either determine orbital periods f…
Two Long-Period Cataclysmic Variable Stars: ASASSN-14ho and V1062 Cyg
L. Claire Gasque, Callum A. Hening, Raphael E. Hviding +5
We report spectroscopy and photometry of the cataclysmic variable stars ASASSN-14ho and V1062 Cyg. Both are dwarf novae with spectra dominated by their secondary stars, which we cl…
CRTS J035010.7+323230, a new eclipsing polar in the cataclysmic variable period gap
Paul A. Mason, Natalie K. Wells, Mokhine Motsoaledi +2
We report the discovery of a new eclipsing polar, CRTS J035010.7+323230 (hereafter CRTS J0350+3232). We identified this cataclysmic variable (CV) candidate as a possible polar from…
High-speed photometry of faint cataclysmic variables - IX. Targets from multiple transient surveys
K. Paterson, P. A. Woudt, B. Warner +5
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…
Optical Studies of 15 Hard X-ray Selected Cataclysmic Binaries
J. P. Halpern, J. R. Thorstensen, P. Cho +5
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 Telesco…
Discovery of an eclipsing dwarf nova in the ancient nova shell Te 11
Brent Miszalski, Patrick A. Woudt, Stuart P. Littlefair +8
We report on the discovery of an eclipsing dwarf nova (DN) inside the peculiar, bilobed nebula Te 11. Modelling of high-speed photometry of the eclipse finds the accreting white dw…
