强磁场中的碳原子

The carbon atom in intense magnetic fields

Anand Thirumalai, Steven J. Desch, Patrick Young

摘要:

计算了碳原子在$\approx 10^7$ T以上强磁场中的前几个低能级。我们扩展了我们以前采用的伪谱方法计算本征态的碳原子。我们报告的基态和一个低洼状态的数据与其他地方的发现非常一致,以及其他十个碳原子状态的新数据,这些状态到目前为止还没有被研究过。可以看出,这些迄今未调查的国家也成为强烈的约束与增加磁场强度。本研究中提供的数据与天体物理学应用有关,如磁化白矮星和中子星光谱分析以及不透明度计算和吸收特征,包括在这些致密物体表面上的物质吸积方面。

英文摘要:

The energy levels of the first few low-lying states of carbon in intense magnetic fields upwards of $\approx 10^7$ T are calculated in this study. We extend our previously employed pseudospectral approach for calculating the eigenstates of the carbon atom. We report data for the ground state and a low-lying state that are in good agreement with findings elsewhere, as well as new data for ten other states of the carbon atom that have not been investigated until now. It is seen that these hitherto uninvestigated states also become strongly bound with increasing magnetic field strengths. The data presented in this study are relevant for astrophysical applications, such as magnetized white dwarf and neutron star spectral analysis as well as opacity calculations and absorption features, including in the context of material accreting onto the surfaces of these compact objects.
