论文摘要
太阳是研究最多，著名的恒星，因此，当需要建模时，太阳基本参数通常用于弥合其他恒星知识的差距。但是，目前可用于推断内部太阳结构的两种最强大，最精确的独立方法是分歧。我们的目的是以太阳为例，展示组成选择在恒星的整体演化中的潜在影响。为此，我们使用金属性和相对元素丰度的不同组合创建了两个标准的太阳能模型，并为每种元素的相对元素丰度和相对元素丰度的不同组合进行了比较，并比较了每个元素的进化，热震和中微子相关的特性。我们报告了在红色巨型分支中校准的模型的年龄差异，该模型的年龄差异超过1 Gyr，发现当前的Atterose震次测量值的精度水平足以区分这些模型，这将在PRIOD间距上显示1.30-2.58％的PRIOD间距差异。此外，我们表明，从碳氮气氧气周期中的中微子通量的测量精度约为17％，这可以通过下一代太阳中微子实验来实现，这可以帮助解决出色的丰度问题。
The Sun is the most studied and well-known star, and as such, solar fundamental parameters are often used to bridge gaps in the knowledge of other stars, when these are required for modelling. However, the two most powerful and precise independent methodologies currently available to infer the internal solar structure are in disagreement. We aim to show the potential impact of composition choices in the overall evolution of a star, using the Sun as an example. To this effect, we create two Standard Solar Models and a comparison model using different combinations of metallicity and relative element abundances and compare evolutionary, helioseismic, and neutrino-related properties for each. We report differences in age for models calibrated to the same point in the HR diagram, in the red giant branch, of more than 1 Gyr, and found that the current precision level of asteroseismic measurements is enough to differentiate these models, which would exhibit differences in priod spacing of 1.30-2.58 per cent. Additionally, we show that the measurement of neutrino fluxes from the carbon-nitrogen-oxygen cycle with a precision of around 17 per cent, which could be achieved by the next generation of solar neutrino experiments, could help resolve the stellar abundance problem.
