TT Aurigae / TT Aur
Light curves and phase diagrams of the EB type eclipsing binary TT Aurigae / TT Aur.
The following light curve and phase diagram were constructed from photometry of 29 images taken with the Bradford Robotic Telescope Cluster Camera (BRT) through their tri-colour green filter between 23 October 2014 and 1 October 2016.
The following primary minimum, on 8 December 2017, was constructed from photometry of 564 unfiltered images taken with the 2" Titan at Somerby Observatory.
The following HJD of the primary minimum was determined from a subset of the above observations, selected to give equal weight to the decline and rise sections of the light curve.
Combining the BRT and Somerby observations into one light curve and phase diagram gave the following figures.
There is o-c activity in this system, which exhibits a small amplitude (approximately +/- 0.01 day), sinusoidal o-c curve with a period of about 20 years (Kreiner).
The catalogued period of this system is given as 1.332735d (GCVS and AAVSO VSX) and 1.3327483d (Kreiner). (Accessed 13 December 2017)
