First multi-colour photometric study of the short period K-type contact binary NSVS 2701634

摘要

We present the first CCD sets of complete light curves for the W Ursae Majoris W-type system NSVS 2701634. The observations were performed in the B, V and I-c bands using the 0.25 m telescope of the "Stazione Astronomica Betelgeuse" Italy, during 8 nights in April 2015.
