Titius-Bode’s Relation and Distribution of Exoplanets [PDF]
Journal of Astronomy and Space Sciences, 2010 The distance distribution in our planetary system has been a controversial matter. Two kinds of important issues on Titius-Bode’s relation have been discussed up to now: one is if there is a simple mathematical relation between distances of natural ...

The Proximities of Asteroids and Critical Points of the Distance Function [PDF]
Serbian Astronomical Journal, 2010 The proximities are important for different purposes,for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets.

On the foundations of general relativistic celestial mechanics [PDF]
, 2017 Towards the end of nineteenth century, Celestial Mechanics provided the most powerful tools to test Newtonian gravity in the solar system, and led also to the discovery of chaos in modern science.

Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser
Advanced Science, EarlyView.An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Degenerate billiards in celestial mechanics [PDF]
Regulârnaâ i haoticeskaâ dinamika, 2016 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 codimension more than one, we say that the billiard is degenerate.

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, EarlyView.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Empirical Stability Criteria for 3D Hierarchical Triple Systems. I. Circumbinary Planets
The Astronomical JournalIn this work we revisit the problem of the dynamical stability of hierarchical triple systems with applications to circumbinary planetary orbits. We derive critical semimajor axes based on simulating and analyzing the dynamical behavior of 3 × 10 ^8 ...
