Abstract
A photometric campaign analysis of the star NSVS 7606408 has been conducted in order to determine the type of variability and high accuracy ephemeris. By combining the obtained data with other datasets available, it was tried to improve the determination of the period, highlighting, however, a possible minimal change of the period over the years. At May 2, 2012, the ephemeris calculated for this variable star is HJDmin = (2456015.44998±1.1 × 10–4) + E |
