The energetics of relativistic magnetic reconnection: ion-electron repartition and particle distribution hardness
Mickaël Melzani, Rolf Walder, Doris Folini +2
Collisionless magnetic reconnection is a prime candidate to account for flare-like or steady emission, outflow launching, or plasma heating, in a variety of high-energy astrophysic…
Simulation of microquasars -- the challenge of scales
Rolf Walder, Mickaël Melzani, Doris Folini +2
We present first results of a long-term project which aims at multi-scale, multi-physics simulations of wind accretion in microquasars and high-mass X-ray binaries. The 3D hydrodyn…
Relativistic magnetic reconnection in collisionless ion-electron plasmas explored with particle-in-cell simulations
Mickaël Melzani, Rolf Walder, Doris Folini +2
Magnetic reconnection is a leading mechanism for magnetic energy conversion and high-energy non-thermal particle production in a variety of high-energy astrophysical objects, inclu…
Differences between real and particle-in-cell plasmas: effects of coarse-graining
Mickaël Melzani, Rolf Walder, Doris Folini +1
The PIC model relies on two building blocks. The first stems from the capability of computers to handle only up to particles, while real plasmas contain from t…
Apar-T: code, validation, and physical interpretation of particle-in-cell results
Mickaël Melzani, Christophe Winisdoerffer, Rolf Walder +4
We present the parallel particle-in-cell (PIC) code Apar-T and, more importantly, address the fundamental question of the relations between the PIC model, the Vlasov-Maxwell theory…
Implicit hydrodynamic simulations of stellar interiors
Maxime Viallet, Isabelle Baraffe, Cedric Mulet-Marquis +4
We report on the development of an implicit multi-D hydrodynamic code for stellar evolution. We present two test-cases relevant for the first scientific goal of the code: the simul…
