标题： MGD Dirac stars

摘要： 几何形变方法（MGD）用于研究紧凑的恒星结构，这些是流体膜上有效爱因斯坦-狄拉克耦合场方程的解。 然后采用非线性、自相互作用的费米场来推导MGD狄拉克星，其特性被分析和讨论。 显示MGD狄拉克星的最大质量随着旋量自相互作用耦合常数的特定函数而增加，在涉及膜张力最严格现象学当前限制的真实模型中。 显示英文摘要

摘要： The method of geometric deformation (MGD) is here employed to study compact stellar configurations, which are solutions of the effective Einstein-Dirac coupled field equations on fluid branes. Non-linear, self-interacting, fermionic fields are then employed to derive MGD Dirac stars, whose properties are analyzed and discussed. The MGD Dirac star maximal mass is shown to increase as an specific function of the spinor self-interaction coupling constant, in a realistic model involving the most strict phenomenological current bounds for the brane tension.
