摘要

本文考虑了重力偏差，并利用这一偏差求解了莱恩-埃姆登方程。首先，我们计算了重力引起的压力和势能，考虑到求解该方程得到的密度，我们得到了白矮星在不同状态下的半径。我们得到了变形参数为零时的普通情况。

Investigation of the white dwarfs based on deformed Lane–Emden equation

In this article, gravity is considered with deviation and we solved the Lane–Emden equation using this deviation, first, we calculated the pressure and potential due to gravity, and considering the density resulting from solving this equation, we obtained the radius of the white dwarf in different states. We obtained the ordinary cases when the deformation parameter goes to zero.
