Abstract

We present the first CCD photometric observations of the northern open cluster NGC 2126. Data were taken on eight nights in February and December 2002 with a total time span of ∼57 hours. Almost 1000 individual V-band frames were examined to find short-period variable stars. We discovered six new variable stars, of which one is a promising candidate for an eclipsing binary with a pulsating component. Two stars were classified as δ Scuti stars and one as Algol-type eclipsing binary. Two stars are slow variables with ambiguous classification. From absolute V(RI)_C photometry we have estimated the main characteristics of the cluster: m - M = 11^m.0 ± 0^m.5, E(V - I) = 0^m.4 ± 0^m.1, E(V - R) = 0^m.08 ± 0^m.06 (E(B - V) = 0 ^m.2 ± 0^m.15) and d = 1.3 ± 0.6 kpc. Cluster membership is suggested for three variable stars from their positions on the colour-magnitude diagram.
