Controlling Artificial Viscosity in SPH simulations of accretion disks [PDF]
, 2010 We test the operation of two methods for selective application of Artificial Viscosity (AV) in SPH simulations of Keplerian Accretion Disks, using a ring spreading test to quantify effective viscosity, and a correlation coefficient technique to measure ...

The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns
Annalen der Physik, Volume 537, Issue 12, December 2025.We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

Gaseous Dynamical Friction on Elliptical Keplerian Orbits
The Astrophysical JournalWe compute the gaseous dynamical friction force experienced by massive perturbers on elliptical Keplerian orbits. Using linear perturbation theory, we investigate the density wake morphology, dynamical friction force, and secular orbital evolution for ...

Motion of spinning particles around dynamic phantom AdS black holes
European Physical Journal C: Particles and Fields, 2023 This work is devoted to discussing spinning particles’ motion in the surrounding dynamic phantom AdS Black hole (BH) with phantom scalar field k. The primary goal of this research is to differentiate between the effects of electric and magnetic charges ...

Element sets for high-order Poincar\'e mapping of perturbed Keplerian motion [PDF]
, 2018 The propagation and Poincar\'e mapping of perturbed Keplerian motion is a key topic in celestial mechanics and astrodynamics, e.g. to study the stability of orbits or design bounded relative trajectories. The high-order transfer map (HOTM) method enables

Energetic Ion Losses Observed During Juno's Close Encounter With Europa
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract We present energetic ion observations made by Juno during its close Europa flyby on 29 September 2022. These data show significant reductions in the ion intensities occurring in the moon's geometric wake region. The most significant losses occur for locally mirroring ions with gyrophases on the anti‐Jovian facing side of the wake.

TTVFast: An efficient and accurate code for transit timing inversion problems
, 2014 Transit timing variations (TTVs) have proven to be a powerful technique for confirming Kepler planet candidates, for detecting non-transiting planets, and for constraining the masses and orbital elements of multi-planet systems.
