AbstractWe present a time-series BV CCD photometry for an EB-type eclipsing binary NSVS 1908107, a member of the young open cluster NGC 869. The photometric solution was obtained by using the 2003 version of the Wilson-Devinney code. It reveals that the system is a semi-detached binary with the secondary component filling its Roche lobe. The mass ratio was determined to be 0.059 +/- 0.001. With the physical parameters of the cluster, the masses, radii and luminosities of the two components of NSVS 1908107 are estimated to be M-1 = 10.34 +/- 2.29 M-circle dot, R-1 = 4. 6 5 +/- 0.34 R-circle dot, L-1 = 8076 +/- 371 L-circle dot and M-2 = 0.61 +/- 0.13 M-circle dot, R-2 = 2.40 +/- 0.17 R-circle dot, L-2 = 1054 +/- 48 L-circle dot respectively. The results show that the secondary component could be a giant or subgiant star with the outer envelope being stripped.
