Photometric study of the eccentric-orbit binary V1147 Cygni.

Abstract (from CDS):

We report photometric observations, an analysis of the resulting light curve, and a preliminary model for the eclipsing binary V1147 Cygni (GSC 2660-2608; mV=12.0). V1147 Cyg is a detached eclipsing system of A-type stars. The sidereal period of the system is 15.2513228(7) days, with an eccentric orbit of e = 0.275(12) and evidence of apsidal motion on the order of 0°.80(11) per century. Our analysis indicates that the stars are well separated and should yield precise main-sequence dimensions. Thus, this is a valuable system in several respects.
