Spectrographic study of the eclipsing binary system SZ Camelopardalis

Abstract

Thirteen high-dispersion spectrographs of the eclipsing binary star SZ Cam have been studied with a view of determining more accurate information on: (i) the spectral type and luminosity classifications, (ii) absolute parameters for the component stars, (iii) the stellar environment of SZ Cam. The main results in these categories are as follows: (i) O9.5 Vnk, (ii)mg=19±2M,ms=6.5±1M;rg=9.7±3.6R,rs=4.8±1.7R;Te∼30000 K,Te∼23000 K; (iii) there is a local concentration of absorbing material which may reach a density of 2M pc−3, and the distance of the star is found to be 600±150 pc. The determined overluminosity of the secondary star and the local concentration of absorbing material are two topics which provide the basis for a discussion section.
