dc.description.abstractNew UBV photometric observations of the recently discovered eccentric orbit binary V401 Lacertae were analyzed by using the Wilson-Devinney program. Seven new minimum times were estimated by using new observations. The analysis of the light Curves and all available minimum time,, has revealed that the system is detached, with the orbital eccentricity e = 0.1734 +/- 0.0003, the longitude of the periastron omega = 63 degrees 93 +/- 0 degrees 15, the rate of change of the longitude of periastron omega 0.degrees 0200 +/- 0.degrees 0024 cycle(-1), corresponding to ail apsidal motion period of U=96.2 +/- 11.4yr. The apsidal motion of the system has been confirmed by the significant difference oil the longitude of periastron (omega) obtained from two light Curves (Hipparcos and ourselves) in two different epochs.
