V717 Andromedae: An Active Low Mass Ratio Contact Binary
S. S. Wadhwa, M. Grozdanovic, N. F. H. Tothill +2
Multi-band photometric analysis of the contact binary V717 Andromedae (V717 And) is presented. The system is found to be an extreme low mass ratio system (q = 0.197) with high incl…
Evolutionary Map of the Universe: Detection and Analysis of the Shell Surrounding the Runaway Wolf-Rayet Star WR16
A. C. Bradley, M. D. Filipović, Z. J. Smeaton +18
We present the first radio--continuum detection of the circumstellar shell around the well-known WN8 type Wolf-Rayet star WR16 at 943.5\,MHz using the \ac{ASKAP} \ac{EMU} survey. A…
Polarization position angle standard stars: a reassessment of and its variability for seventeen stars based on a decade of observations
Daniel V. Cotton, Jeremy Bailey, Lucyna Kedziora-Chudczer +14
Observations of polarization position angle () standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters in bot…
Photometric and Spectroscopic Study of Two Low Mass Ratio Contact Binary Systems: CRTS J225828.7-121122 and CRTS J030053.5+230139
Surjit S. Wadhwa, Jelena Petrovic, Nick F. H. Tothill +3
The study reports photometric and spectroscopic observations of two recently recognised contact binary systems. Both systems show total eclipses and analysis of the light curves in…
A Study of Six Extreme Low Mass Ratio Contact Binary Systems
Surjit S. Wadhwa, Bojan Arbutina, Jelena Petrovic +4
Multi-band (B, V and R) photometric and spectroscopic observations of six poorly studied contact binaries carried out at the Western Sydney University and Las Cumbres Observatory w…
A Study of Twelve Potential Merger Candidate Contact Binary Systems
Surjit S. Wadhwa, Bojan Arbutina, Nick F. H. Tothill +4
Photometric observations and analysis of twelve previously poorly studied contact binary systems is presented. All show total eclipses and have extremely low mass ratios ranging fr…
