摘要

本文讨论了伽玛射线暴(GRB)光学光曲线出现准周期振荡的模型。该模型基于一个假设，即伽马射线暴发生在一个有强烈恒星风的双星系统中。祖星是一个小的氦核恒星，它发出强烈的恒星风，被紧凑的伴星(中子星)扰动。以GRB160625B为例，对MASTER全球网接收到的高时间分辨率光曲线进行了模型参数的计算。

THE GRB PROMPT OPTICAL EMISSION FEATURES ON THE EXAMPLE OF GRB160625B

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.
