乌普萨拉大学研究团队通过改进的太阳大气模型，发现太阳的含银量比之前的科学估计高出55%[1]。该研究由物理与天文系博士生Sema Caliskan主导，采用了结合动态模型与原子物理计算的新型测量方法，使得对太阳光谱线的解读更加准确[1]。这一发现使太阳的银含量数据与约46亿年前与古代陨石共同形成的原始气尘云中的银含量更加一致[1]。
新方法首次被应用于分析太阳中的银元素，研究团队利用瑞典国家超级计算中心的Tetralith超级计算机完成了相关计算[1]。这项工作有助于更好地追踪宇宙中银等重元素的起源，而太阳中的重元素仅占其总质量的1.5%[1]。
Researchers at Uppsala University have found that the Sun contains 55% more silver than previously estimated [1]. The discovery was made by doctoral student Sema Caliskan from the Department of Physics and Astronomy, who employed an advanced solar atmospheric model combined with dynamic modeling and atomic physics calculations to more accurately interpret spectral lines [1].
The new measurement approach has brought the Sun's silver abundance into closer alignment with the silver content found in ancient meteorites, providing better insight into the origins of heavy elements throughout the cosmos [1]. According to the research, heavy elements account for only 1.5% of the Sun's total mass [1]. The Sun and these ancient meteorites are believed to have formed approximately 4.6 billion years ago from the same cloud of gas and dust [1]. The study utilized Sweden's National Supercomputer Centre's Tetralith supercomputer to conduct the analysis [1], marking the first time this methodology has been applied to silver element analysis in the Sun [1].
