The first two orbits of the Parker Solar Probe (PSP) spacecraft have enabled in situ measurements solar wind down to a heliocentric distance 0.17 au (or 36 Rs). Here, we present an analysis this data study turbulence at and its evolution out 1 au. While many features remain similar, key differences include: increased energy levels by more than order magnitude, magnetic field spectral index -3/2 matching that velocity both Elsasser fields, lower compressibility consistent with smaller...
Abstract We have recently developed a new modeling capability to embed the implicit particle‐in‐cell (PIC) model iPIC3D into Block‐Adaptive‐Tree‐Solarwind‐Roe‐Upwind‐Scheme magnetohydrodynamic (MHD) model. The MHD with embedded PIC domains (MHD‐EPIC) algorithm is two‐way coupled kinetic‐fluid As one of very first applications MHD‐EPIC algorithm, we simulate interaction between Jupiter's magnetospheric plasma and Ganymede's magnetosphere. compare simulations pure Hall both results Galileo...
Abstract In van der Holst et al. (2019), we modeled the solar corona and inner heliosphere of first encounter NASA’s Parker Solar Probe (PSP) using Alfvén Wave atmosphere Model (AWSoM) with Air Force Data Assimilative Photospheric flux Transport–Global Oscillation Network Group magnetograms, made predictions state wind plasma for encounter. AWSoM uses low-frequency wave turbulence to address coronal heating acceleration. Here, revise our simulations, by introducing improvements in energy...
Abstract Typical planetary and satellite exospheres are in nonequilibrium conditions, which means that a distribution function describes these environments is far from Maxwellian. It even more true when considering transportation of energetic ions magnetospheres, making it necessary to solve the Boltzmann equation order capture kinetic effects modeling evolution describing such environments. Among various numerical methods, Monte Carlo approach one most used for solving equations. That...
Abstract Neutral hydrogen has been shown to greatly impact the plasma flow in heliosphere and location of heliospheric boundaries. We present results Solar Wind with Hydrogen Ion Exchange Large-scale Dynamics (SHIELD) model, a new, self-consistent, kinetic–MHD model outer within Space Weather Modeling Framework. The charge exchange mean free path is on order size heliosphere; therefore, neutral atoms cannot be described as fluid. numerical code SHIELD couples MHD solution for single fluid...
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one the primary means studying phenomenon. With increasing accessibility such grows demand for user-friendly tools that would facilitate process simulating CMEs scientific and operational purposes. The Eruptive Event Generator based on Gibson-Low flux rope (EEGGL), new publicly...
Solar Energetic Particles (SEPs) are an important aspect of space weather. SEP events posses a high destructive potential, since they may cause disruptions communication systems on Earth and be fatal to crew members onboard spacecrafts and, in extreme cases, harmful people altitude flights. However, currently the research community lacks efficient tools predict such hazardous threat its potential impacts. Such tool is first step for mankind improve preparedness ultimately able mitigate their...
Abstract Electron acceleration in solar flares is well known to be efficient at generating energetic particles that produce the observed bremsstrahlung X-ray spectra. One mechanism proposed explain observations electron within contracting magnetic islands formed by reconnection flare current sheet. In a previous study, numerical magnetohydrodynamic simulation of an eruptive was analyzed estimate associated due island contraction. That analysis used simple analytical model for structure and...

The ability to restart the engine after its shutdown in flight has a significant impact on safety and is also one of certification requirements for manned aircraft. Unmanned aircraft must be able perform an emergency landing event impossibility re-lighting combustion chamber flight, example, when it impossible achieve idle speed operating at windmill modes. Compliance with these mandatory certification. Confirmation required performance requires complex expensive rig tests. Preliminary...
