Photometric and Spectroscopic Study of PU Pup

Abstract

We present the analysis of photometric and spectroscopic observations of the Southern eclipsing binary star PU Pup. We solved the HIPPARCOS light curve of PU Pup and proposed a relatively close binary star model with a rather low mass ratio and low inclination to give the ellipsoidal form of its light variation. Spectroscopic observations of the system were made at the Mt. John University Observatory in 2008 and 2014. Since the light contribution of the secondary component was only 1% of the light contribution of the primary component in the optical wavelengths, the radial velocities of the primary component could be measured. A single-lined spectroscopic orbital solution of PU Pup then was obtained.
