The first photometric investigation of the neglected short period binary DY CVn

Q ZhiNing, J LinQiao, L Jie, H YanFei, Y YuQuan - New Astronomy, 2017 - Elsevier
We present new photometric observations of the short period binary DY CVn. By using the
Wilson-Devinney code of 2013 version, we found that DY CVn is a shallow contact binary (f …

New Photometric Investigation of the Solar‐Type Shallow‐Contact Binary HH Bootis

J He, J Wang - Advances in Astronomy, 2019 - Wiley Online Library
The short‐period solar‐type contact binary HH Boo was monitored photometrically for about
8 years. It is found that the CCD light curves in the B, V, R, and I bands obtained in 2010 are …
