Period changes in the eclipsing binaries DG Lacertae and MZ Lacertae.

SILHAN J.

Abstract (from CDS):

DG Lac and MZ Lac have been observed visually and studied on plates of the Sonneberg Sky Survey. The orbits of both systems proved to be eccentric. MX Lac displays apsidal motion and DG Lac shows a reflection effect. The orbital period of DG Lac increased abruptly in the early 1960's.
