Abstract

We search for observational evidence that is in agreement with the model of a binary star system in gamma-ray bursts (GRBs), as presented in [1–3]. The model predicts three distinctly temporal and spectral properties, which could be identified by the observational data. Here we present a detailed time-resolved spectral analysis for several bright GRBs (GRB 130427A, 160509A, 160625B, and 190114C), and find that all of them are consistent with the expectation predicted by the model.
