An OB-type eclipsing binary system ALS 1135

We present new physical and orbital parameters of an early-type double-lined eclipsing binary system ALS 1135. The UBVI_C light curves and radial velocity curves were modeled simultaneously by means of the Wilson-Devinney code. As a result, we obtained inclination and size of the orbit, as well as masses, radii and effective temperatures of the components.
