The third realization of the International Celestial Reference Frame by very long baseline interferometry
P. Charlot, C. S. Jacobs, D. Gordon +17
A new realization of the International Celestial Reference Frame (ICRF) is presented based on the work achieved by a working group of the International Astronomical Union (IAU) man…
Topological approach to the generalized -center problem
Sergey Bolotin, Valery Kozlov
We consider a natural Hamiltonian system with two degrees of freedom and Hamiltonian . The configuration space is a closed surface (for noncompact certain…
Degenerate billiards in celestial mechanics
Sergey Bolotin
In an ordinary billiard trajectories of a Hamiltonian system are elastically reflected after a collision with a hypersurface (scatterer). If the scatterer is a submanifold of codim…

The ICRF-3: Status, plans, and progress on the next generation International Celestial Reference Frame
Z. Malkin, C. S. Jacobs, F. Arias +17
The goal of this presentation is to report the latest progress in creation of the next generation of VLBI-based International Celestial Reference Frame, ICRF3. Two main directions…
Shilnikov Lemma for a nondegenerate critical manifold of a Hamiltonian system
Sergey Bolotin, Piero Negrini
We prove an analog of Shilnikov Lemma for a normally hyperbolic symplectic critical manifold of a Hamiltonian system. Using this result, trajectories with smal…
