Topological changes of the photospheric magnetic field inside active regions: a prelude to flares
L. Sorriso-Valvo, V. Carbone, V. Abramenko +5
The observations of magnetic field variations as a signature of flaring activity is one of the main goal in solar physics. Some efforts in the past give apparently no unambiguous o…

Heap-based algorithm for one-dimensional particle systems
Alain Noullez, Duccio Fanelli, Erik Aurell
A fast algorithm to study one-dimensional self-gravitating systems, and, more generally, systems that are Lagrangian integrable between collisions, is presented. The algorithm is e…
