摘要

研究对象是最近发现的三颗来自快速轴向旋转、质量M≤M（cid:12）的双星系统的白矮星。基于平衡方程，并根据观测到的质量和轴向旋转周期，计算了白矮星V1460 Her在电子核模型内的几何和力学特性（惯性矩、赤道重力、与旋转相关的稳定条件）。对白矮星LAMOST的模型参数和宏观特征进行了估计，这些参数和特征是根据观测旋转周期推断的

Inverse problem of white dwarfs theory with rapid axial rotation

. The objects of research are three recently discovered white dwarfs from binary systems with rapid axial rotation and masses M ≤ M (cid:12) . The geometrical and mechanical characteristics (moment of inertia, equatorial gravity, the condition of stability in relation to rotation) are calculated for the white dwarf V1460 Her within an electron-nuclear model, based on the equilibrium equation and inferred from observations mass and period of axial rotation. Estimates of model parameters and macroscopic characteristics for inferred from observations periods of rotation are performed for white dwarfs LAMOST
