摘要:

我们在麻省理工学院袋模型的框架内发现了带电夸克物质的爱因斯坦-麦克斯韦方程组的新一类解,考虑了Thirukkanesh和Ragel(2013)提出的引力势Z(x),它取决于可调参数n。变量的能量密度,电荷密度,压力和度规函数写在初等和多项式函数。我们表明,选择的形式的引力势允许获得物理上可接受的解决方案与任何值的可调参数。

英文摘要:

We found new class of solutions to the Einstein-Maxwell system of equations for charged quark matter within the framework of MIT Bag Model considering a gravitational potential Z(x) proposed by Thirukkanesh and Ragel (2013), which depends on an adjustable parameter n. Variables as the energy density, charge density, pressure and the metric functions are written in terms of elementary and polinominal functions. We show that the form chosen for the gravitational potential allows obtain physically acceptable solutions with any value of the adjustable parameter.
