A few questions related to white dwarfs’ physics is posed. It seems that the modified gravity framework can be a good starting point to provide alternative explanations to cooling processes, their age determination, and Chandrasekhar mass limits. Moreover, we have also obtained the Chandrasekhar limit coming from Palatini f(ℛ) gravity provided by a simple Lane–Emden model.

修正重力的白矮星

提出了一些与白矮星物理学有关的问题。似乎修改后的重力框架可以作为一个很好的起点，为冷却过程、它们的年龄确定和钱德拉塞卡质量限制提供替代解释。此外，我们还得到了来自 Palatini 的 Chandrasekhar 极限F(ℛ)由简单的 Lane-Emden 模型提供的重力。
