A new way to find symbiotic stars: accretion disc detection with continuum survey photometry
A. B. Lucy, J. L. Sokoloski, G. J. M. Luna +10
Symbiotic stars are binaries in which a cool and evolved star of luminosity class I-III accretes onto a smaller companion. However, direct accretion signatures like disc flickering…
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…
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…
Discovery, observations and modelling of a new eclipsing polar: MASTER OT J061451.70-272535.5
H. Breytenbach, D. A. H. Buckley, P. Hakala +9
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 MAS…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
