New Light Curves of LP133-373 Reveal Flaring, A Refined Period and an Initial Epoch.

TERRACCIANO N. and VACCARO T.

Abstract (from CDS):

We present new CCD Johnson V and Cousins R photometric data on the eclipsing binary LP133-373. Analysis includes the detection of a flare event, eclipse timings and a refined period and initial epoch for the system. The new ephemeris for this system is T = 2452760.70523 ± 0.00045 + 1.6279850 ± 4.3805144 × 10–7 × e. Previous studies by others have mentioned period changes and radial velocity changes over time, so we continue to monitor LP133-373.
