“Fireshell”模型和“规范”GRB场景
The "fireshell" model and the "canonical" GRB scenario
摘要:
在“火壳”模型中,我们定义了一个“正则GRB”光变曲线,其中有两个截然不同的分量:当产生这种现象的电子-正电子等离子体的光学厚火壳达到透明时发出的正确GRB(P-GRB),以及由于剩余的光学薄火壳和CircumBurst介质(CBM)之间的碰撞而发出的余辉。我们概述了我们的“规范伽玛暴”的情况下,起源于引力坍缩到一个黑洞,与“真正的”和“假的”短伽玛暴之间的区别特别强调。
英文摘要:
In the "fireshell" model we define a "canonical GRB" light curve with two sharply different components: the Proper-GRB (P-GRB), emitted when the optically thick fireshell of electron-positron plasma originating the phenomenon reaches transparency, and the afterglow, emitted due to the collision between the remaining optically thin fireshell and the CircumBurst Medium (CBM). We outline our "canonical GRB" scenario, originating from the gravitational collapse to a black hole, with a special emphasis on the discrimination between "genuine" and "fake" short GRBs.
