Taking into account results obtained from models and analyses , we determined the nature and structures of V1003 Her .
We analysed the light curves obtained in this study together with the available radial velocity curve .
The analysis revealed that the inclination ( i ) of the system was found to be 45 ^ { \circ } .82 \pm 2 ^ { \circ } .71 , while the semi-major axis ( a ) was computed as 2.925 \pm 0.143 R _ { \odot } .
The mass of the primary component was found to be 1.204 \pm 0.004 M _ { \odot } , while it was obtained as 0.450 \pm 0.006 M _ { \odot } for the secondary component .
The radius of the primary component was computed as 1.424 \pm 0.001 R _ { \odot } , while it was computed as 0.904 \pm 0.001 R _ { \odot } for the secondary component .
The analysis indicates that there are two spotted areas close to each other on the surface of the secondary component .
In addition , B-band light and B - V colour curves reveal that there is a radiation excess toward the phase of 0.40 .
This should be caused due to some heating of the surface by the events like thermal flare , or the structures like plage .
Finally , the analysis and model demonstrated that V1003 Her should be a near-contact binary with high level magnetic activity on its surface .
