Validation of MHD Model Predictions of the Corona with LASCO-C2 Polarized Brightness Images

Progress in our understanding of the solar corona requires that the results of advanced magnetohydrodynamic models driven by measured magnetic fields, and particularly the underlying heating models, be thoroughly compared with coronal observations. The comparison has so far mainly concerned the global morphology of the corona, synthetic images calculated from the models being compared with observed images. We go one step further by performing detailed quantitative comparisons between the calculated polarized radiance p B ...

Predicting the Structure of the Solar Corona and Inner Heliosphere during Parker Solar Probe \textquoterights First Perihelion Pass

NASA\textquoterights Parker Solar Probe (PSP) spacecraft reached its first perihelion of 35.7 solar radii on 2018 November 5. To aid in mission planning, and in anticipation of the unprecedented measurements to be returned, in late October, we developed a three-dimensional magnetohydrodynamic (MHD) solution for the solar corona and inner heliosphere, driven by the then available observations of the Sun\textquoterights photospheric magnetic field. Our model incorporates a wave-turbulence-driven model to heat the corona. He ...

Nanodust in the Heliosphere

The NASA Parker Solar Probe and the ESA Solar Orbiter will explore the source region of the solar wind within 20 solar radii. Their unprecedented in-situ measurements are also expected to shed light on the nature of the F-corona and the existence of a halo of nanodust. Such a dust complex might play an important role in the generation of high-speed nanodust grains and the inner-source pickup ions. A brief summary of previous works on this topic is given here to be followed by a sketch on a plan to integrate MHD simulation of ...

On the Limitations of Taylor s Hypothesis in Parker Solar Probe s Measurements near the Alfven Critical Point

In this Letter, we present an analysis of two-point, two-time correlation functions from high-resolution numerical simulations of Reflection-driven Alfven Turbulence near the Alfven critical point r e . The simulations model the turbulence in a prescribed background solar wind model chosen to match observational constraints. This analysis allows us to investigate the temporal decorrelation of solar wind turbulence and the validity of Taylor s approximation near the heliocentric distance r(c), which Parker Solar Probe (PSP) i ...

Prospective White-light Imaging and In Situ Measurements of Quiescent Large-scale Solar-wind Streams from the Parker Solar Probe and Solar Orbiter

Deep-space exploration of the inner heliosphere is in an unprecedented golden age, with the recent and forthcoming launches of the Parker Solar Probe (PSP) and Solar Orbiter (SolO) missions, respectively. In order to both predict and understand the prospective observations by PSP and SolO, we perform forward MHD modeling of the 3D inner heliosphere at solar minimum, and synthesize the white-light (WL) emission that would result from Thomson scattering of sunlight from the coronal and heliospheric plasmas. Both solar rotat ...

Simulated Encounters of the Parker Solar Probe with a Coronal-hole Jet

Solar coronal jets are small, transient, collimated ejections most easily observed in coronal holes (CHs). The upcoming Parker Solar Probe (PSP) mission provides the first opportunity to encounter CH jets in situ near the Sun and examine their internal structure and dynamics. Using projected mission orbital parameters, we have simulated PSP encounters with a fully three-dimensional magnetohydrodynamic (MHD) model of a CH jet. We find that three internal jet regions, featuring different wave modes and levels of compressibi ...

Selection of Critical Design Parameters for MMOD Protection in Interplanetary Missions

This paper presents a methodology for the selection of critical design-parameters for the design of Micro Meteoroid and Orbital Debris (MMOD) spacecraft protection based on a modified implementation of the concept of the Probability of No Impact (PNI). The PNI methodology, based on Poisson s discrete statistics, has been widely used to determine critical particle sizes for the design of protection systems. However, it does not provide guidelines for the selection of the design impact speed, especially when the impact speed h ...

Short wavelength electromagnetic perturbations excited near the Solar Probe Plus spacecraft in the inner heliosphere: 2.5D hybrid modeling

A 2.5D numerical plasma model of the interaction of the solar wind (SW) with the Solar Probe Plus spacecraft (SPPSC) is presented. These results should be interpreted as a basic plasma model derived from the SW interaction with the spacecraft (SC), which could have consequences for both plasma wave and electron plasma measurements on board the SC in the inner heliosphere. Compression waves and electric field jumps with amplitudes of about 1.5 V/m and (12-18) V/m were also observed. A strong polarization electric field was ...
