We present the first multi-color light curve analysis of the eclipsing binary star NSVS 7051868.
- •
The system belong to the A-subtype W Ursae Majoris systems.
- •
A moderate degree of contact and a relatively large difference of temperature between the components is found.
- •
NSVS 7051868 may be in a key evolutionary stage of the TRO theory.
- •
Its position in the H-R diagram is showed and the physical parameter are estimated.
