由于精细结构常数而导致的约化的Brachasekhar质量极限
Reduced Chandrasekhar mass limit due to the fine-structure constant
摘要：
电磁相互作用改变了一个因素，这取决于，如在文献中计算的，在简并物质中存在的带正电荷的原子核的原子序数的卡拉塞卡质量限制。不幸的是，这种计算所采用的方法打破了洛伦兹从头算不变性。采用有限温度相对论量子场论的方法，我们证明了电磁相互作用的作用使非广义相对论、球对称白矮星的Krasekhar质量极限在首阶降低了一个普适因子$(1-3α/4π)$，其中$α$为精细结构常数.
英文摘要：
The electromagnetic interaction alters the Chandrasekhar mass limit by a factor which depends, as computed in the literature, on the atomic number of the positively charged nuclei present within the degenerate matter. Unfortunately, the methods employed for such computations break Lorentz invariance ab initio. By employing the methods of finite temperature relativistic quantum field theory, we show that in the leading order, the effect of electromagnetic interaction reduces the Chandrasekhar mass limit for non-general-relativistic, spherically symmetric white dwarfs by a universal factor of $(1-3α/4π)$, $α$ being the fine-structure constant.
