The New Ephemeris and Light Curve Analysis of V870 Ara by the Ground-Based and TESS Data

New CCD photometric observations and their investigation of the W UMa-type binary, V870 Ara, are presented. Light curves of the system were taken through BVIfilters from the Congarinni Observatory in Australia. The new ephemeris is calculated based on seven new determined minimum times, together wit...
