Abstract

Photometric analysis of the ASAS-SN V-band photometry of V633 Virginis is presented. The results show an A-type system with an extreme low mass ratio of 0.14 and mid-range contact of 33%. There is good thermal contact between the components. Some astrophysical qualities are examined, and some absolute parameters of the system determined.
