三维超新星:与伽马射线暴的联系

Supernovae in Three-Dimension: A Link to Gamma-Ray Bursts

Keiichi Maeda

摘要:

一个喷流驱动的超新星(SN)爆炸模型的观测结果。结果进行了详细的比较与光学观测SN 1998 bw与伽马射线暴。结果表明,喷流模型是能够重现几乎所有的光学观测可用于此SN,虽然一个球形模型未能解释一些观察到的功能。由于视角效应,SN喷出物所需的动能与之前的球形模型所获得的动能(~ 5 x 10^{52} erg)相比减少到~ 2 x 10 ^{52} erg,但这仍然远远大于规范SN的动能(~10^{51} erg)。

英文摘要:

Observational consequences of a jet-driven supernova (SN) explosion model are presented. The results are compared in detail with optical observations of SN 1998bw associated with a Gamma-Ray Burst. It is shown that the jet model is able to reproduce virtually all the optical observations available for this SN, although a spherical model fails to explain some of observed features. Because of the viewing angle effect, the required kinetic energy of the SN ejecta is reduced to ~ 2 x 10^{52} erg as compared to that obtained by the previous spherical model (~ 5 x 10^{52} erg), but this is still much larger than that of a canonical SN (~10^{51} erg).
