标题： Limits on the proton-proton reaction cross-section from helioseismology

摘要： 太阳振荡频率的主要反转结合热平衡方程和其他输入物理参数，使我们能够推断太阳内部的温度和氢含量分布。 这些分布还有助于设定与准确测量的振荡频率数据一致的输入物理参数的约束。 根据太阳核心中重元素丰度，推导出质子-质子核反应截面的日震学限制。 我们证明，在日震学约束下，无法同时推断重元素丰度分布以及温度和氢含量分布。 显示英文摘要

摘要： Primary inversions of solar oscillation frequencies coupled with the equations of thermal equilibrium and other input physics, enable us to infer the temperature and hydrogen abundance profiles inside the Sun. These profiles also help in setting constraints on the input physics that is consistent with the accurately measured oscillation frequencies data. Helioseismic limits on the cross-section of proton-proton nuclear reaction as a function of heavy element abundance in the solar core are derived. We demonstrate that it is not possible to infer the heavy element abundance profile, in addition to temperature and hydrogen abundance profiles, with the helioseismic constraints.
