New times of minima and ephemeris for several OB eclipsing binaries.

MAYER P., NIARCHOS P.G., LORENZ R., WOLF M. and CHRISTIE G.

Abstract (from CDS):

New times of minimum light were measured for several early-type eclipsing binaries: V337 Aql, V1182 Aql, V1331 Aql, IU Aur, QZ Car and V382 Cyg. The O-C diagram for these systems is discussed and new ephemeris is given for AH Cep; observation of AQ Cir is added. It is shown that the scatter of times of minima is several times larger than the measuring errors for most of the binaries studied.
