行星模型中的CO状态方程

An Equation of State of CO for use in Planetary Modeling

Morris Podolak, Amit Levi, Allona Vazan, Uri Malamud

摘要:

虽然一氧化碳(CO)是一种丰富的分子,可能对行星内部有很大的重要性,但由于其极端的挥发性,对其性质的测量是困难的。我们计算的CO状态方程的温度和密度的范围内,适用于行星内部的条件。以前的实验和理论研究只涵盖了有限的温度-密度范围。我们的计算与这些早期结果吻合得很好,但现在涵盖了所有相关性。计算方法基于More等人(1988年)描述的通用状态方程,此处使用该方程以生成供社区使用的可免费下载的查找表。

英文摘要:

Although carbon monoxide (CO) is an abundant molecule and may have great importance for planetary interiors, measurements of its properties are difficult due to its extreme volatility. We calculate the equation of state for CO over a range of temperature and density that is applicable to the conditions in planetary interiors. Previous experimental and theoretical studies cover only a limited temperature-density range. Our calculations match these early results well, but now cover the full range of relevance. The method of calculation is based on the general-purpose quotidian equation of state described by More et al. (1988), which is here used in order to generate a freely downloadable look-up table to be used by the community.
