r-Java 2.0: the astrophysics
摘要：
本文是介绍r-Java 2.0的两部分系列文章中的第二部分，r-Java 2.0是一个开放使用的核合成代码，它执行r过程计算并提供一套其他分析工具。[Aims第一篇文章讨论了r-Java 2.0固有的核物理，本文将详细介绍软件中包含的天体物理。[方法：] R-Java 2.0允许用户指定r过程模拟的密度和温度演变。定义物理参数（温度和密度）如何演化可以有效地模拟r过程的天体物理条件。在r-Java 2.0中，用户可以选择天体物理环境，这些环境具有独特的输入参数集，可供用户调整。在这项工作中，我们研究了三个建议的r-过程网站：中微子驱动的风周围的原中子星，喷出物从中子星合并和喷出物从夸克新星。在这项工作中描述了定义每个站点的温度和密度演化的基本物理学。[结果]本文对各个天体物理场的可用参数进行了调查，并比较了它们对最终r过程丰度的影响。由此产生的丰度为每个网站也比较太阳观测独立和一致。R-Java 2.0可从Quark-Nova项目网站下载：www.example.com
英文摘要：
[Context:] This article is the second in a two part series introducing r-Java 2.0, a nucleosynthesis code for open use that performs r-process calculations and provides a suite of other analysis tools. [Aims:] The first paper discussed the nuclear physics inherent to r-Java 2.0 and in this article the astrophysics incorporated into the software will be detailed. [Methods:] R-Java 2.0 allows the user to specify the density and temperature evolution for an r-process simulation. Defining how the physical parameters (temperature and density) evolve can effectively simulate the astrophysical conditions for the r-process. Within r-Java 2.0 the user has the option to select astrophysical environments which have unique sets of input parameters available for the user to adjust. In this work we study three proposed r-process sites; neutrino-driven winds around a proto-neutron star, ejecta from a neutron star merger and ejecta from a quark nova. The underlying physics that define the temperature and density evolution for each site is described in this work. [Results:] In this paper a survey of the available parameters for each astrophysical site is undertaken and the effect on final r-process abundance is compared. The resulting abundances for each site are also compared to solar observations both independently and in concert. R-Java 2.0 is available for download from the website of the Quark-Nova Project: http://quarknova.ucalgary.ca/
