A parametric study of solar wind properties and composition using fluid and kinetic solar wind models
Paul Lomazzi, Alexis P. Rouillard, Michael A. Lavarra +7
The physical processes in the solar corona that shape the solar wind remain an active research topic. Modeling efforts have shown that energy and plasma exchanges near the transiti…
Variability of the slow solar wind: New insights from modelling and PSP-WISPR observations
Nicolas Poirier, Victor Réville, Alexis P. Rouillard +2
We analyse the signature and origin of transient structures embedded in the slow solar wind, and observed by the Wide-Field Imager for Parker Solar Probe (WISPR) during its first t…
HelioCast: heliospheric forecasting based on white-light observations of the solar corona. I. Solar minimum conditions
Victor Réville, Nicolas Poirier, Athanasios Kouloumvakos +8
We present a new 3D MHD heliospheric model for space-weather forecasting driven by boundary conditions defined from white-light observations of the solar corona. The model is based…
Confined plasma transition from the solar atmosphere to the interplanetary medium
Nicolas Poirier, Alexis Rouillard, Pierre-Louis Blelly
The last 60 years of space exploration have shown that the interplanetary medium is continually perturbed by a myriad of different solar winds and storms that transport solar mater…
Constraining Global Coronal Models with Multiple Independent Observables
Samuel T. Badman, David H. Brooks, Nicolas Poirier +13
Global coronal models seek to produce an accurate physical representation of the Sun's atmosphere which can be used, for example, to drive space weather models. Assessing their acc…
Flux ropes and dynamics of the heliospheric current sheet
V. Réville, N. Fargette, A. P. Rouillard +19
Context. Solar Orbiter and PSP jointly observed the solar wind for the first time in June 2020, capturing data from very different solar wind streams, calm and Alfvénic wind as wel…
Solar wind rotation rate and shear at coronal hole boundaries, possible consequences for magnetic field inversions
R. F. Pinto, N. Poirier, A. P. Rouillard +6
In-situ measurements by several spacecraft have revealed that the solar wind is frequently perturbed by transient structures (magnetic folds, jets, waves, flux-ropes) that propagat…
Source-dependent properties of two slow solar wind states
Léa Griton, Alexis P. Rouillard, Nicolas Poirier +3
Two states of the slow solar wind are identified from in-situ measurements by Parker Solar Probe (PSP) inside 50 solar radii from the Sun. At such distances the wind measured at PS…
Investigating the origin of the FIP effect with a shell turbulence model
Victor Réville, Alexis P. Rouillard, Marco Velli +4
The enrichment of coronal loops and the slow solar wind with elements that have low First Ionisation Potential, known as the FIP effect, has often been interpreted as the tracer of…
Coronal Bright Points as possible sources of density variations in the Solar Corona
Léa Griton, Rui F. Pinto, Nicolas Poirier +3
Recent analysis of high-cadence white-light images taken by the Solar-Terrestrial RElations Observatory (STEREO) near solar maximum has revealed that outflowing density structures…
Modeling the Early Evolution of a Slow Coronal Mass Ejection Imaged by the Parker Solar Probe
Alexis P. Rouillard, Nicolas Poirier, Michael Lavarra +9
During its first solar encounter, the Parker Solar Probe (PSP) acquired unprecedented up-close imaging of a small Coronal Mass Ejection (CME) propagating in the forming slow solar…
Relating streamer flows to density and magnetic structures at the Parker Solar Probe
Alexis P. Rouillard, Athanasios Kouloumvakos, Angelos Vourlidas +34
The physical mechanisms that produce the slow solar wind are still highly debated. Parker Solar Probe's (PSP's) second solar encounter provided a new opportunity to relate in situ…
Detailed imaging of coronal rays with the Parker Solar Probe
Nicolas Poirier, Athanasios Kouloumvakos, Alexis P. Rouillard +13
The Wide-field Imager for Solar PRobe (WISPR) obtained the first high-resolution images of coronal rays at heights below 15 R when the Parker Solar Probe (PSP) was located…
