RW Geminorum / RW Gem
Light curve and phase diagram of the EA type eclipsing binary RW Geminorum / RW Gem. These were constructed from 25 images taken with the Bradford Robotic Telescope Cluster Camera (BRT) between 2014 October 30 and 2016 January 11. The images were taken through a tri-colour green filter.
A secondary minimum was observed with the 2" Titan from Somerby Observatory on 2022 January 27. The images were not filtered and the results have not been transformed. There is an 11.08 mag star (UCAC4 566-021502) in the same measurement aperture as RW Gem (ie blended with it) which has not been subtracted from these results.
The change in magnitude is small, and the scatter is relatively large compared to it, which prevented an accurate determination of the time of minimum.
The above observations have been combined into the following light curve and phase diagram. The BRT observations are in black, the Somerby observations are in red.
The catalogue period for this star is 2.8654972d (GCVS, AAVSO VSX) and 2.8654982d (Kreiner). There is little o-c activity evident for this star (Kreiner). (Accessed 2022 January 29.)
