The evolution of inverted magnetic fields through the inner heliosphereABSTRACT

Local inversions are often observed in the heliospheric magnetic field (HMF), but their origins and evolution are not yet fully understood. Parker Solar Probe has recently observed rapid, Alfv\ enic, HMF inversions in the inner heliosphere, known as \textquoterightswitchbacks\textquoteright, which have been interpreted as the possible remnants of coronal jets. It has also been suggested that inverted HMF may be produced by near-Sun interchange reconnection; a key process in mechanisms proposed for slow solar wind release. ...

On the Origin of Ortho-Gardenhose Heliospheric Flux

Parker-spiral theory predicts that the heliospheric magnetic field (HMF) will have components of opposite polarity radially toward the Sun and tangentially antiparallel to the solar rotation direction (i.e., in Geocentric Solar Ecliptic (GSE) coordinates, with BX/BY<0). This theory explains the average orientation of the HMF very well indeed but does not predict the so-called ortho-gardenhose (hereafter OGH) flux with which is frequently observed. We here study the occurrence and structure of OGH flux, as seen in near-Earth ...

Generation of Inverted Heliospheric Magnetic Flux by Coronal Loop Opening and Slow Solar Wind Release

In situ spacecraft observations provide much-needed constraints on theories of solar wind formation and release, particularly the highly variable slow solar wind, which dominates near-Earth space. Previous studies have shown an association between local inversions in the heliospheric magnetic field (HMF) and solar wind released from the vicinity of magnetically closed coronal structures. We here show that in situ properties of inverted HMF are consistent with the same hot coronal source regions as the slow solar wind. We ...

The Solar Probe Plus Mission: Humanity\textquoterights First Visit to Our Star

Solar Probe Plus (SPP) will be the first spacecraft to fly into the low solar corona. SPP\textquoterights main science goal is to determine the structure and dynamics of the Sun\textquoterights coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what processes accelerate energetic particles. Understanding these fundamental phenomena has been a top-priority science goal for over five decades, dating back to the 1958 Simpson Committee Report. The scale and concept of su ...

The Solar Probe Plus (SPP) spacecraft will orbit as closely as 9.5 solar radii from the sun; so close that its thermal protection shield (TPS) will reach a peak temperature of 1,400C. To work in this environment, the solar array will use pressurized water cooling and operate in the penumbra formed by the TPS at a 68 degrees angle of incidence. Even with these mitigations, the array will be subject to extremely high intensity and temperature. This paper will summarize the array s environment, present a preliminary design, out ...
