标题： Slowly rotating proto strange stars in Quark mass density- and temperature- dependent model

摘要： 利用夸克质量和温度相关的模型以及哈特尔的方法，我们研究了具有均匀角速度的缓慢旋转的奇异星。给出了不同频率下的质量-半径关系、转动惯量和框架拖拽效应。我们发现，不能用奇异星来解决Stella和Vietri提出的水平分支振荡和转动惯量$I_{45}/(M/M_ s)>2.3$的挑战。此外，我们将哈特尔的方法扩展到研究差速旋转的奇异星，发现差速旋转是一种获得大质量奇异星的有效方法。 显示英文摘要

摘要： Employing the Quark Mass Denisity- and temperature- dependent model and the Hartle's method, We have studied the slowly rotating strange star with uniform angular velocity. The mass-radius relation, the moment of inertia and the frame dragging for different frequencies are given. We found that we cannot use the strange star to solve the challenges of Stella and Vietri for the horizontal branch oscillations and the moment of inertia $I_{45}/(M/M_ s)>2.3$. Furthermore, we extended the Hartle's method to study the differential rotating strange star and found that the differential rotation is an effective way to get massive strange star.
