摘要

本文综述了宽谱线Ic型超新星的观测现状和理论解释。它们的特点是光球膨胀快，不吸收氢和氦。它们的能量预算比正常情况下要大，这表明它们是由一个中央引擎驱动的，或者至少是由一个中央引擎增强的，比如磁星或吸积黑洞。因此，这些超新星和长时间的伽马射线爆发之间似乎存在联系。然而，它的性质并没有令人满意地揭开神秘面纱。

Gamma-ray burst jets in supernovae

We review the current observational status and theoretical interpretations for the class of broad lines type Ic supernovae. They are characterized by fast photospheric expansion and lack of H and He absorption. They have a larger than normal energy budget, suggesting that they are powered or, at least, augmented by a central engine, like a magnetar or an accreting black hole. There appears therefore to be a link between these supernovae and long-duration gamma-ray bursts. However, its nature has not been satisfactorily demystified.

期刊介绍： New Astronomy Reviews publishes review articles in all fields of astronomy and astrophysics: theoretical, observational and instrumental. This international review journal is written for a broad audience of professional astronomers and astrophysicists. The journal covers solar physics, planetary systems, stellar, galactic and extra-galactic astronomy and astrophysics, as well as cosmology. New Astronomy Reviews is also open for proposals covering interdisciplinary and emerging topics such as astrobiology, astroparticle physics, and astrochemistry.
