Theory and Observations of Supernovae

惠勒，J.克雷格”超新星的理论和观测“AST-0098644有证据表明，超新星，当被用作距离指标，可能指向一个有限的宇宙常数和宇宙的加速膨胀的宇宙学重新引起了人们的兴趣。此外，最近还发现了超新星和伽马射线暴之间的联系。因此，了解不同类型的超新星变得比以往任何时候都更加重要。在这个奖项中，关于超新星的观测和理论的三个主要主题将被追求。首先是更好地理解Ia型超新星及其在测量宇宙学距离方面的应用。这将涉及使用Hobby-Eberly望远镜进行观测，以及在其他观测站获得红外光谱。第二个主题是探索超新星的偏振性及其对超新星爆发不对称性的影响。第三项主要任务是建立磁流体动力学过程的理论模型，这些过程涉及可能产生所观察到的喷流和不对称现象的地核坍缩。

Wheeler, J. Craig" Theory and Observation of Supernovae "AST- 0098644There is a renewed interest in cosmology with the evidence that supernovae, when used as distance indicators, may point to a finite cosmological constant and an accelerating expansion of the universe. In addition, there has been a recent link between a supernova and a gamma-ray burst. Understanding the different types of supernovae has thus become more important than ever before. In this award, three major themes concerning the observation and theory of supernovae will be pursued. The first is to understand better Type Ia supernovae and their application to measure cosmological distances. This will involve observations with the Hobby-Eberly telescope and infrared spectra obtained at other observatories. The second theme is to explore the polarization of supernovae and its implications about the asymmetry of supernova outbursts. The third major undertaking will be to construct theoretical models of the magnetohydrodynamic processes involved in core collapse that may produce jets and asymmetries of the sort observed.
