一类新的具有Karmarkar条件的EFE的可行精确解：在冷星模拟中的应用
A new class of viable and exact solutions of EFE's with Karmarkar conditions: An application to cold star modeling
摘要：
在这项工作中，我们提出了一个理论框架内爱因斯坦的经典广义相对论模型恒星紧凑的对象，如PSR J1614-2230和SAX J1808.4-3658。爱因斯坦场方程的求解是通过假设紧致物体的内部由I类时空描述来实现的。从这个要求所产生的所谓的Karmarkar条件被集成到一个单一的生成函数的引力行为。通过诉诸物理学，我们采用了一种引力势的形式，这种形式足够稳健，可以精确地描述紧凑的物体。我们的模型满足物理上真实的恒星结构的所有要求。
英文摘要：
In this work we present a theoretical framework within Einstein's classical general relativity which models stellar compact objects such as PSR J1614-2230 and SAX J1808.4-3658. The Einstein field equations are solved by assuming that the interior of the compact object is described by a class I spacetime. The so-called Karmarkar condition arising from this requirement is integrated to reduce the gravitational behaviour to a single generating function. By appealing to physics we adopt a form for the gravitational potential which is sufficiently robust to accurately describe compact objects. Our model satisfies all the requirements for physically realistic stellar structures.
