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…
