论文摘要
在GRB 170817A及时发射持续一秒钟之后，已获取X射线，光学波长和无线电波长中的$ 10^8 $ S数据。我们在这里提出了一个模型，该模型根据所有这些排放的光谱，通量和时间变异性，该模型基于在二进制白矮人合并中弹出的膨胀物的热和同步加速器冷却。 $ 10^{ - 3} m_ \ odot $ of ejecta，以$ 10^9 $ cm s $ s $^{ - 1} $的速度扩展，由新生儿大型，快速旋转，磁性磁化的白矮人的质量为1.3 m_ \ odot $ $ $ \ gtrsim 12 $ s，sim a sim a gtrsim 12 $ s，a sim a sim sim sim a s y s s y s y s s s＆s s s sim 12 $ s，a sim 12 $ s，s an 10^{10} $ g，出生于$ 1.0+0.8 m_ \ odot $ white dwarf二进制的合并中。因此，GRB 170817a自然的持久奥秘是通过白矮二元的合并来解决的，这也解释了迅速的发射能量。
Following the GRB 170817A prompt emission lasting a fraction of a second, $10^8$ s of data in the X-rays, optical, and radio wavelengths have been acquired. We here present a model that fits the spectra, flux, and time variability of all these emissions, based on the thermal and synchrotron cooling of the expanding matter ejected in a binary white dwarf merger. The $10^{-3} M_\odot$ of ejecta, expanding at velocities of $10^9$ cm s$^{-1}$, are powered by the newborn massive, fast rotating, magnetized white dwarf with a mass of $1.3 M_\odot$, a rotation period of $\gtrsim 12$ s, and a dipole magnetic field $\sim 10^{10}$ G, born in the merger of a $1.0+0.8 M_\odot$ white dwarf binary. Therefore, the long-lasting mystery of the GRB 170817A nature is solved by the merger of a white dwarf binary that also explains the prompt emission energetics.
