Eine photometrische Loesung fur den Doppelstern V381 Canis Majoris.

HAUCK N.

Abstract (from CDS):

V381 CMa is known as a bright eclipsing binary system having an orbital period of 3.4 days. Modelling of old and new photometric data now revealed an annular eclipse in the primary minimum, i.e. a transit of a smaller and cooler companion in front of the A-type star primary component. By combining the obtained relative parameters of the components with stellar models a mass of about 2.76 Msun and a radius of 4.39 Rsun has been derived for the A-type star, and a mass of about 0.79 Msun and a radius of 0.72 Rsun for the secondary component having a Teff of about 4850 K. Apparently, the components of the binary can be classified as an A-type subgiant and a K-type dwarf. [The online version of this paper is written in German and English].
