论文摘要
在本工作中，作者在存在两个场轴（但丁的地狱模型）的存在下，为相对论紧凑的恒星提供精确的解，并且具有与重力相关的复杂标量场（具有四分之一的自我相互作用）与重力耦合。该物质源被认为是完美的流体，我们还使用Brotropic/MIT袋EOS来得出能量密度和各向异性/各向同性压力，来自爱因斯坦田间方程（EFE）。为简单起见，作为度量电位，我们使用tolman-kuchowicz度量势，这些势能是非单一且物理上可接受的。 T-K度量电位的未知变量来自连接条件。为了检查红移功能，绝热指数和能量，因果关系条件我们使用了诸如PSR J1416-223，PSR J1903+32、4U 1820-30，CEN X-3，EXO 1785-248，SAX J1808.4365之类的紧凑型星。
In the present work authors derive exact solutions for the relativistic compact stars in the presence of two fields axion (Dante's Inferno model) and with/without the complex scalar field (with the quartic self-interaction) coupled to gravity. The matter source is assumed as the perfect fluid one, and we also use barotropic/MIT bag EoS to derive energy density and anisotropic/isotropic pressures from Einstein Field Equations (EFE's). For simplicity, as the metric potentials we use Tolman-Kuchowicz metric potentials, which are non-singular and physically acceptable. Unknown variables for the T-K metric potentials were derived from the junction conditions. To examine the redshift function, adiabatic index and energy, causality conditions we used such compact stars as PSR J1416-223, PSR J1903+32, 4U 1820-30, Cen X-3, EXO 1785-248, SAX J1808.4365.
