Stellar heavy-element slope index
AI总结:
研究恒星重元素分布,用唯象方法引入相关参数并考虑斜率参数,探讨普遍性等情况,其有助于表征重元素形成条件,不过重元素产生场所尚待明确。
AI中文摘要:
采用唯象方法描述恒星中重元素的分布,在冻结概念中引入与温度以及质子和中子化学势相关的拉格朗日参数。考虑了描述重元素分布总体行为的斜率参数,讨论了普遍性及偏离情况并给出示例。这些斜率参数可能有助于表征重元素形成的条件,但重元素产生的天体物理场所仍有待确定。
英文摘要:
The distribution of heavy elements in stars is described using a phenomenological approach, in which Lagrange parameters related to temperature and the chemical potentials of protons and neutrons are introduced within a freeze-out concept. Slope parameters are considered which describe the gross behavior of the distribution of the heavy elements. Universality and deviations from universality are discussed, and various examples are provided. These slope parameters may be of interest for characterizing the conditions under which heavy elements form, but the astrophysical sites where heavy elements are produced remain to be determined.
