太阳丰度问题的最新讨论

An updated discussion of the solar abundance problem

F. L. Villante, A. Serenelli

摘要:

我们讨论了新一代标准太阳模型(SSM),巴塞罗那2016或简称B16,与日震和太阳中微子数据的一致性水平,证实了基于太阳大气的精细三维流体动力学模拟,实现AGSS 09 met表面丰度的模型不会再现日震约束。我们澄清,这个太阳能丰度的问题可以同样解决的太阳等离子体的组成和/或不透明度的变化,因为金属丰度的变化所产生的影响是等同于通过适当的修改所产生的太阳不透明度的配置文件。我们讨论了在CNO循环中产生的中微子对于消除成分不透明度简并的重要性以及未来探测的前景。

英文摘要:

We discuss the level of agreement of a new generation of standard solar models (SSMs), Barcelona 2016 or B16 for short, with helioseismic and solar neutrino data, confirming that models implementing the AGSS09met surface abundances, based on refined three-dimensional hydrodynamical simulations of the solar atmosphere, do not not reproduce helioseismic constraints. We clarify that this solar abundance problem can be equally solved by a change of the composition and/or of the opacity of the solar plasma, since effects produced by variations of metal abundances are equivalent to those produced by suitable modifications of the solar opacity profile. We discuss the importance of neutrinos produced in the CNO cycle for removing the composition-opacity degeneracy and the perspectives for their future detection.
