简单的食谱紧凑的残余群众和natal踢

Simple recipes for compact remnant masses and natal kicks

Ilya Mandel, Bernhard Müller

摘要:

基于最近的三维超新星模拟和半解析参数化模型的结果,我们开发的分析处方的质量的依赖性的中子星和黑洞和出生踢,如果有的话,对前超新星的碳氧核和氦壳质量。为了解释恒星演化和超新星的内在随机性,我们的配方是概率性的,而不是确定性的。我们预计,这些食谱将是特别有用的快速人口合成,我们说明了他们的应用程序的残余质量和踢人口的单星分布。

英文摘要:

Based on recent results from three-dimensional supernova simulations and semi-analytical parametrised models, we develop analytical prescriptions for the dependence of the mass of neutron stars and black holes and the natal kicks, if any, on the pre-supernova carbon-oxygen core and helium shell masses. Our recipes are probabilistic rather than deterministic in order to account for the intrinsic stochasticity of stellar evolution and supernovae. We anticipate that these recipes will be particularly useful for rapid population synthesis, and we illustrate their application to distributions of remnant masses and kicks for a population of single stars.
