This article discusses a model for the occurrence of quasiperiodic oscillations in the optical light curve of a gamma-ray burst(GRB). The model is based on the assumption that GRB occurs in a binary system with strong stellar wind. Progenitor is a small core of helium star which emits a strong stellar wind that perturbs by the compact companion (neutron star).There is a calculation of model parameters by using the GRB160625B as an example, for which the MASTER global network received an optical curve with high time resolution.
