RU Sextantis / RU Sex
Light curve and phase diagram of the RRC type variable star RU Sextantis / RU Sex. These were constructed from photometry of 21 images taken with the Bradford Robotic Telescope Galaxy Camera (BRT) between 2012 December 4 and 2016 January 11 using a V filter.
This star was discussed by Brelstaff and Isles (Journal of the British Astronomical Association, 1986, 97, 1). It is currently (February 2019) listed in the GCVS as an EB type eclipsing binary with a period of 13.07d. However, the AAVSO VSX shows it as an RRC type variable with a period of 0.350232d, as concluded by Brelstaff and Isles. (GCVS and AAVSO VSX accessed 2019 February 5.) Although there are too few data points in this present sample to be definitive, the above phase diagram is plotted with this latter period.
