A New Framework for Modeling Solar Flares from MHD to Kinetic Processes
Joel C. Allred, Graham S. Kerr, Silvina E. Guidoni +4
Physical processes in solar flares span many orders of magnitude in spatiotemporal scales, so a single unified model accounting for all relevant processes remains computationally i…
Solar Wind Proton Implantation and Hydrogen Diffusion: Model Comparisons to M3 Observations
O. J. Tucker, W. M. Farrell, S. Li +3
The Moon Mineralogy Mapper (M3) observed a widespread 3-micron absorption feature on the lunar surface, commonly attributed to surficial OH and/or H2O. The feature varies with lati…
Advancing Heliophysics and Space Weather Modeling through Open Science
C. Corti, M. M. Kuznetsova, M. A. Reiss +85
We present a community-wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potenti…
Interaction between a Coronal Mass Ejection and Comet 67P/Churyumov-Gerasimenko
Zhenguang Huang, Gabor Toth, Tamas I. Gombosi +6
The interaction between a Coronal Mass Ejection (CME) and a comet has been observed several times by in-situ observations from the Rosetta Plasma Consortium (RPC), which is designe…
Neutral gas coma dynamics: modeling of flows and attempts to link inner coma structures to properties of the nucleus
Raphael Marschall, Björn J. R. Davidsson, Martin Rubin +1
Deriving properties of cometary nuclei from coma data is of significant importance for our understanding of cometary activity and has implications beyond. Ground-based data represe…
Application of the Monte Carlo Method in Modeling Transport and Acceleration of Solar Energetic Particles
Valeriy Tenishev, Lulu Zhao, Igor Sokolov
The need for quantitative characterization of the solar energetic particle (SEP) dynamics goes beyond being an academic discipline only. It has numerous practical implications rela…
The development of a split-tail heliosphere and the role of non-ideal processes: a comparison of the BU and Moscow models
M. Kornbleuth, M. Opher, I. Baliukin +11
Global models of the heliosphere are critical tools used in the interpretation of heliospheric observations. There are several three-dimensional magnetohydrodynamic (MHD) heliosphe…
Exosphere Modeling of Proxima b: A Case Study of Photochemical Escape with a Venus-like Atmosphere
Yuni Lee, Chuanfei Dong, Valeriy Tenishev
Exoplanets orbiting M-dwarfs within habitable zones are exposed to stellar environments more extreme than that terrestrial planets experience in our Solar System, which can signifi…
Magnetohydrodynamic with Adaptively Embedded Particle-in-Cell model: MHD-AEPIC
Yinsi Shou, Valeriy Tenishev, Yuxi Chen +2
Space plasma simulations have seen an increase in the use of magnetohydrodynamic (MHD) with embedded Particle-in-Cell (PIC) models. This combined MHD-EPIC algorithm simulates some…
What Sustained Multi-Disciplinary Research Can Achieve: The Space Weather Modeling Framework
Tamas I. Gombosi, Yuxi Chen, Alex Glocer +15
MHD-based global space weather models have mostly been developed and maintained at academic institutions. While the "free spirit" approach of academia enables the rapid emergence a…
The Confinement of the Heliosheath Plasma by the Solar Magnetic Field as Revealed by Energetic Neutral Atom Simulations
M. Kornbleuth, M. Opher, A. T. Michael +4
Traditionally, the solar magnetic field has been considered to have a negligible effect in the outer regions of the heliosphere. Recent works have shown that the solar magnetic fie…
The Solar-wind with Hydrogen Ion Exchange and Large-scale Dynamics (SHIELD) model: A Self-Consistent Kinetic-MHD Model of the Outer Heliosphere
Adam T. Michael, Merav Opher, Gabor Toth +2
Neutral hydrogen has been shown to greatly impact the plasma flow in the heliopshere and the location of the heliospheric boundaries. We present the results of the Solar-wind with…
High Resolution Finite Volume Method for Kinetic Equations with Poisson Brackets
Igor V. Sokolov, Haomin Sun, Gabor Toth +6
Simulation of plasmas in electromagnetic fields requires numerical solution of a kinetic equation that describes the time evolution of the particle distribution function. In this p…
The Surface Distributions of the Production of the Major Volatile Species, H2O, CO2, CO and O2, from the Nucleus of Comet 67P/Churyumov-Gerasimenko throughout the Rosetta Mission as Measured by the ROSINA Double Focusing Mass Spectrometer
Michael Combi, Yinsi Shou, Nicolas Fougere +12
The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) suite of instruments operated throughout the over two years of the Rosetta mission operations in the vicinity…
A comparison between the two lobes of comet 67P/Churyumov-Gerasimenko based on D/H ratios in H2O measured with the Rosetta/ROSINA DFMS
