论文摘要
在$ f \ left（r，t \ right）= r +2βT$重力的情况下，其中$ r $是ricci scalar，$ t $是能量 - 摩托张量的痕迹，被带电各向异性的各向异性白矮人（WDS）的平衡结构。得出了一般情况的恒星方程，并找到了Chandrasekhar状态方程（EOS）的数值解，并且电荷密度分布与能量密度$ρ_ {\ text {ch}}} =αρ$成比例。通过调整不同的参数，比较了各种条件下溶液的性质。最重要的是，通过以各种方式超越GR的琐碎WD，解决方案可能会表现出超级智障行为。本文是对WD结构的研究，获得的结果可能对天文观测（例如超小IA型超新星）具有对比影响。
In the context of $f\left(R, T\right) = R + 2 βT$ gravity, where $R$ is the Ricci scalar and $T$ is the trace of the energy-momentum tensor, the equilibrium structure of charged anisotropic white dwarfs (WDs) is studied. The stellar equations for the general case are derived and numerical solutions are found for the Chandrasekhar equation of state (EoS) and a charge density distribution proportional to the energy density $ρ_{\text{ch}} = αρ$. By adjusting different parameters, the properties of the solutions under various conditions are compared. Most importantly, by going beyond the trivial WD in GR in various ways, the solutions may exhibit super-Chandrasekhar behavior. This article is a study of a WD structure, and the results obtained may have a contrasting effect on astronomical observations such as superluminous type Ia supernovae.
