Аннотация:We have obtained the first photoelectric light curve of the eclipsing binary GSC 4292-
0745, discovered by Otero et al. (2006). These observations have enabled us to construct
for the first time a consistent model of the binary and to discover the fast apsidal
rotation of its orbit. The object is very important as a test of stellar evolution theory, and
needs further photometric and spectroscopic observations. Interestingly, the star seems
to be affected by very strong interstellar absorption, as are other young stars on elliptic
orbits such as GG Ori (E(B−V) = 0.53; Volkov & Khaliullin 2002) or GSC 3152-1202
(E(B − V) = 1.71, our own unpublished measurement). Perhaps we are witnessing
dissipated dusty circumstellar shells.
