论文摘要
伽马射线爆发（GRB）是所有电磁频谱中前所未有的复杂性系统的系统，包括无线电，光学，X射线，MegaelectRoctRonvolt（MEV）和GigaelectRonvolt（MEV）和Gigaelectronvolt（GEV）（GEV）（GEV），以及超级效果的特定范围（每个范围）（每个范围）（每个范围）（uhecress），每个差异（uhecress），以及各种特定的范围（UHECRESS），以及各种范围（UHECRESS），以及各种特定的范围，并在Uhecress中进行了范围。 $ 10^{ - 14} $ s到$ 10^{7} $ s或更长时间。在这里，我们研究了长GRB 180720b源自二进制系统，该系统由大约$ 10 m_ \ odot $的巨大碳氧（CO）星组成，并伴有中子星（NS）。 CO星的重力崩溃产生了旋转的新生儿NS（$ν$ ns），初始期间为$ p_0 = 1 $ ms，为无线电，光学和X射线波长的同步辐射提供动力。我们在这里仅研究GRB 180720b的余气，并根据由$ν$ ns和SN射流释放的同步加速器辐射对其来源进行详细处理。我们表明，与X射线余辉并行，旋转$ν$ ns还为光学和无线电余波提供动力，并允许我们推断符合观测数据的$ν$ ns和弹出参数。
Gamma-ray bursts (GRBs) are systems of unprecedented complexity across all the electromagnetic spectrum, including the radio, optical, X-rays, gamma-rays in the megaelectronvolt (MeV) and gigaelectronvolt (GeV) regime, as well as ultrahigh-energy cosmic rays (UHECRs), each manifested in seven specific physical processes with widely different characteristic evolution timescales ranging from $10^{-14}$ s to $10^{7}$ s or longer. We here study the long GRB 180720B originating from a binary system composed of a massive carbon-oxygen (CO) star of about $10 M_\odot$ and a companion neutron star (NS). The gravitational collapse of the CO star gives rise to a spinning newborn NS ($ν$NS), with an initial period of $P_0=1$ ms that powers the synchrotron radiation in the radio, optical, and X-ray wavelengths. We here only investigate the GRB 180720B afterglows and present a detailed treatment of its origin based on the synchrotron radiation released by the interaction of the $ν$NS and the SN ejecta. We show that in parallel to the X-ray afterglow, the spinning $ν$NS also powers the optical and radio afterglows and allows us to infer the $ν$NS and ejecta parameters that fit the observational data.
