Title: 探索爱因斯坦引力修正理论中特殊、次临界和超临界Ia型超新星之间的缺失环节

Abstract: Observations of several peculiar, under- and over-luminous type Ia supernovae (SNeIa) argue for exploding masses widely different from the Chandrasekhar-limit. We explore the modification to Einstein's gravity in white dwarfs for the first time in the literature, which shows that depending on the (density dependent) modified gravity parameter $\alpha$, chosen for the present purpose of representation, limiting mass of white dwarfs could be significantly sub- as well as super-Chandrasekhar. Hence, this unifies the apparently disjoint classes of SNeIa, establishing the importance of modified Einstein's gravity in white dwarfs. Our discovery questions both the global validity of Einstein's gravity and the uniqueness of Chandrasekhar's limit. Show Chinese abstract

Abstract: 对几种特殊的、亮度不足和过度的Ia型超新星（SNeIa）的观测表明，爆炸质量与钱德拉塞卡极限相差很大。 我们首次在文献中探讨了白矮星中爱因斯坦引力的修正，这表明根据目前表示的目的选择的（密度相关的）修正引力参数$\alpha$，白矮星的质量极限可能显著地低于以及高于钱德拉塞卡极限。 因此，这统一了SNeIa看似不相关的类别，确立了修正后的爱因斯坦引力在白矮星中的重要性。 我们的发现质疑了爱因斯坦引力的全局有效性以及钱德拉塞卡极限的独特性。
