Variations of angular momentum as an indicator of orbital chaos of globular clusters in the central region of the Galaxy with a bar
A. T. ~Bajkova, A. A. ~Smirnov, V. V. ~Bobylev
It is shown how the violation of the invariance of the -component of the orbital angular momentum in the axially symmetric potential of the Galaxy with a bar can serve as…
The Spiral Pattern Speed in the Milky Way Galaxy
Vadim V. Bobylev, Anisa T. Bajkova, Anton A. Smirnov
For a sample of masers, the basic kinematic equations were solved by including the Galactic rotation parameters and the peculiar velocity of the Sun as the unknown variables. Based…
