Arches of chaos, heteroclinic connections of first-order MMRs and the chaotic transport of small bodies in the Sun-Jupiter system
Alessia Francesca Guido, Christos Efthymiopoulos
We investigate the heteroclinic connections between stable and unstable manifolds of unstable periodic orbits associated with the most important mean motion resonances (MMRs) in th…
Analytical study of chaos and applications
G. Contopoulos, M. Harsoula, C. Efthymiopoulos
We summarize various cases where chaotic orbits can be described analytically. First we consider the case of a magnetic bottle where we have non-resonant and resonant ordered and c…
Combining particle acceleration and coronal heating via data-constrained calculations of nanoflares in coronal loops
C. Gontikakis, S. Patsourakos, C. Efthymiopoulos +2
We model nanoflare heating of extrapolated active-region coronal loops via the acceleration of electrons and protons in Harris-type current sheets. The kinetic energy of the accele…
Particle interactions with single or multiple 3D solar reconnecting current sheets
A. Anastasiadis, C. Gontikakis, C. Efthymiopoulos
The acceleration of charged particles (electrons and protons) in flaring solar active regions is analyzed by numerical experiments. The acceleration is modelled as a stochastic pro…
