【摘要】 本文用一阶微扰理论讨论了有核的转动多层球平衡结构,并给出数值解。结果表明,核的质量越大,多层球转动的临界中心角速度Ω_ocrl就越小。而在相同的中心自转角速度下,核的质量越大,旋转棉球的扁率ξ_a/ξ_p也越大。本文还讨论了较差转动参数b对有核多层球平衡结构的影响。更多还原

【Abstract】 The equilibrium structure of rotating polytropes with a compact core has been studied by means of Chandrasekhar’s first-order perturbation theory. Several numerical solusions have been done. The results show that the larger the core mass, the less the critical central angular velocity, and for the same angular velocity, the more large the core mass, the more large the oblateness of the rotation ellipsoid.更多还原
