Evidence for High Eccentricity and Apsidal Motion in the Detached Eclipsing Binary GSC 04052-01378.

FURGONI R. and BILLINGS G.

Abstract (from CDS):

We observed the recently discovered eccentric eclipsing binary GSC 04052-01378 in order to improve the light curve parameters and to find further evidence of its probable high eccentricity and of apsidal motion. Furthermore, we propose a basic stellar model that fits very well the observations of our dataset and where the eccentricity is found to be e = 0.538(6), which corresponds to an high value among this group of binaries.
