dc.description.abstractThis paper presents the first analysis of spectroscopic and photometric observations of the southern eclipsing binary star MW Pup. ASAS V light and SAAO radial velocity curves of the system were solved simultaneously using Wilson-Devinney code. The results describe MW Pup as an Algol-like binary star with a detached configuration. The masses of the components were found to be 2.20 +/- 0.06 and 1.88 +/- 0.07 M-circle dot and the radii to be 1.84 +/- 0.03 and 1.72 +/- 0.03 R-circle dot for primary and secondary components, respectively. The distance to MW Pup was calculated to be 430 +/- 30 pc from the dynamic parallax, neglecting interstellar absorption, in agreement with the value derived from the eclipse-parallax method. The evolution of the system is also discussed. Both components are unevolved Main Sequence stars and the dynamic age of the system is estimated as 263 +/- 70 My when compared to theoretical evolution models. (C) 2014 Elsevier B.V.
