Abstract

We present results of new photometric observations of the contact binary system HI Pup as well as the radial velocity curve of the system. Time series multicolour photometry was obtained at the South African Astronomical Observatory (SAAO) using the 1-m Cassegrain Telescope. We applied a simultaneous solution to the BVRI light and radial velocity curves in order to determine the physical parameters of the system. From an analysis of the new multicolour data, the physical parameters were found to be M1=1.22 M,M2=0.23M,R1=1.44R, R2=0.67R,L1=3.3L, L2=0.7L. Our solution confirms that HI Pup has a typical A-type W UMa binary system characteristics.
