| Popis: | We present results of new photometric observations of the contact binary system \astrobj{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 $M_1=1.22M_{\odot}$, $M_2=0.23M_{\odot}$, $R_1=1.44R_{\odot}$, $R_2=0.67R_{\odot}$, $L_1=3.3L_{\odot}$, $L_2=0.7L_{\odot}$. Our solution confirms that HI Pup has a typical A--type W UMa binary system characteristics. Comment: 12 pages, 3 Figures, 3 Tables. Accepted for publication in New Astronomy |
