太阳能氩电池

The Solar Argon Abundance

Katharina Lodders

摘要:

太阳氩的丰度不能直接由太阳光球层的光谱观测得到。太阳Ar丰度的评估从太阳风测量,核合成参数,观测B星,HII地区,行星状星云,和惰性气体丰度测量木星的大气。根据这些数据,推荐的氩丰度为N(Ar)= 91,200(+/-)23,700(在Si = 10^6原子的范围内)。太阳光球层的推荐丰度(在log N(H)= 12的标度上)为A(Ar)photo = 6.50(+/-)0.10,考虑到元素沉降,太阳系(原太阳)的丰度为A(Ar)solsys = 6.57(+/-)0.10。

英文摘要:

The solar argon abundance cannot be directly derived by spectroscopic observations of the solar photosphere. The solar Ar abundance is evaluated from solar wind measurements, nucleosynthetic arguments, observations of B stars, HII regions, planetary nebulae, and noble gas abundances measured in Jupiter's atmosphere. These data lead to a recommended argon abundance of N(Ar) = 91,200(+/-)23,700 (on a scale where Si = 10^6 atoms). The recommended abundance for the solar photosphere (on a scale where log N(H) = 12) is A(Ar)photo = 6.50(+/-)0.10, and taking element settling into account, the solar system (protosolar) abundance is A(Ar)solsys = 6.57(+/-)0.10.
