    • Abstract


      When observing the transiting extrasolar planets, we found a new eclipsing binary named GSC 02265-01456. The 𝑉 and 𝑅c observations were carried out for this binary. The photometric light curves of the two bands were simultaneously analyzed using the W–D code. The solutions show that GSC 02265-01456 is an extremely low mass ratio (𝑞 = 0.087) overcontact binary system with a contact degree of 𝑓 = 82.5%. The difference between the two maxima of the light curve can be explained by a dark spot on the primary component.

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
