Four-colour photometry of eclipsing binaries. XIIb. TV Ceti, light curves, photometric elements and determination of helium content.
Abstract
Summary. Photometric elements are derived for the eclipsing binary TV Ceti using the model simulation method of Wood. Combining these data with spectroscopic elements, the absolute dimensions are found. The components are only little evolved and the fit to calculated evolutionary tracks is perfect. The helium content is found to be Y= 0.20+0.04. Key words: eclipsing binary - uvby photometry - light curves - photometric elements - absolute dimensions - helium content
