Dynamical environments of Arrokoth: prior evolution and present state
Disciplines :
astronomy & astrophysics
Collected date : from 1 Jan 2022 to 1 Aug 2022
We consider dynamical environments of (486958) Arrokoth, focusing on both their present state and their long-term evolution, starting from the KBO's formation.
Massive evaluation and analysis of Poincaré recurrences
Disciplines :
physics, mathematical
astronomy & astrophysics
Collected date : from 2018 ongoing
We present a novel numerical method aimed to characterize global behaviour, in particular chaotic diffusion, in dynamical systems. It is based on an analysis of the Poincaré recurrence statistics on massive grids of initial data or values of parameters. We concentrate on Hamiltonian systems, ...
