Scientific paper

We present an analysis of recently published photometry of OW Geminorum during its 2002 eclipse season. The photometric data are analyzed simultaneously with previously published radial velocities. The results show that OW Gem consists of an F2 Ib-II primary with M1=5.8+/-0.2 Msolar, R1=30.1+/-0.3 Rsolar and a G8 IIb secondary with M2=3.9+/-0.1 Msolar, R2=31.7+/-0.3 Rsolar. We discuss the evolutionary implications of these results.
