Magnetohydrodynamical origin of eclipsing time variations in post-common-envelope binaries for solar mass secondaries

, 2019
| openaire: EC/H2020/665667/EU//EPFL FellowsEclipsing time variations have been observed for a wide range of binary systems, including post-common-envelope binaries. A frequently proposed explanation, apart from the possibility of having a third body, is

A Novel Optimized Local Linearization Hybrid Block Method for Chaotic Systems: Applications to Stretch‐Twist‐Fold Flow and Bond Orbital Chaotic Attractors

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The numerical approximation of nonlinear chaotic differential systems, such as the modified stretch‐twist‐fold (STF) flow and multi‐bond chaotic attractors, presents a significant challenge due to their sensitive dependence on initial conditions and complex dynamics where analytical solutions are unattainable.

Radio Evolution of Supernova Remnants Including Nonlinear Particle Acceleration: Insights from Hydrodynamic Simulations [PDF]

, 2018
We present a model for the radio evolution of supernova remnants (SNRs) obtained by using three-dimensional hydrodynamic simulations coupled with nonlinear kinetic theory of cosmic-ray (CR) acceleration in SNRs.

A Coscaling Grid for Athena++. II. Magnetohydrodynamics

The Astrophysical Journal Supplement Series
We extend the coscaling formalism of Habegger & Heitsch implemented in Athena++ to magnetohydrodynamics. The formalism relies on flow symmetries in astrophysical problems involving expansion, contraction, and center-of-mass motion. The formalism is fully

RESISTIVE MAGNETOHYDRODYNAMIC SIMULATIONS OF RELATIVISTIC MAGNETIC RECONNECTION [PDF]

The Astrophysical Journal, 2010
Resistive relativistic magnetohydrodynamic (RRMHD) simulations are applied to investigate the system evolution of relativistic magnetic reconnection. A time-split Harten--Lan--van Leer method is employed. Under a localized resistivity, the system exhibits a fast reconnection jet with an Alfvénic Lorentz factor inside a narrow Petschek-type exhaust ...

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Compact Tubular Dielectric Elastomer Pump for Indoor Plants

Journal of Applied Polymer Science, Volume 143, Issue 25, July 5, 2026.
This study develops a mountable rolled dielectric elastomer pump (MRDEP) using silicone films and MWCNT‐based electrodes. The MRDEP is completely soft, silent in operation, and easily mounted on a piping system. We use dry stacking methods, fabricate a multilayer dielectric elastomer actuator (DEA), and a pre‐straining process in one direction before ...
