Abstract

The motion of stars in galactic disks is considered in the epicyclic approximation in a potential derived from gauge gravitation theory. It is assumed that the instability of circular orbits of stars with respect to small perturbations in such a potential can lead to the formation of spiral arms. We find the values of the unknown coefficients from the lagrangian of gauge gravitation theory such that they allow such an instability to occur.

规范引力理论中星系的螺旋结构

摘要

星系盘中恒星的运动在周转逼近中被认为是由规范引力理论推导出来的。假定恒星的圆形轨道相对于这种潜在的微小扰动的不稳定性会导致形成旋臂。我们从规范引力理论的拉格朗日法中找到未知系数的值,这样它们就可以发生这种不稳定性。
