On the Origin of the sudden Heliospheric Open Magnetic Flux Enhancement during the 2014 Pole Reversal
Stephan G. Heinemann, Mathew J. Owens, Manuela Temmer +12
Coronal holes are recognized as the primary sources of heliospheric open magnetic flux (OMF). However, a noticeable gap exists between in-situ measured OMF and that derived from re…
Slow Solar Wind Connection Science during Solar Orbiter's First Close Perihelion Passage
Stephanie L. Yardley, Christopher J. Owen, David M. Long +76
The Slow Solar Wind Connection Solar Orbiter Observing Plan (Slow Wind SOOP) was developed to utilise the extensive suite of remote sensing and in situ instruments on board the ESA…
Unifying the Validation of Ambient Solar Wind Models
Martin A. Reiss, Karin Muglach, Richard Mullinix +18
Progress in space weather research and awareness needs community-wide strategies and procedures to evaluate our modeling assets. Here we present the activities of the Ambient Solar…
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…
Implementing the MULTI-VP coronal model in EUHFORIA: test case results and comparisons with the WSA coronal model
Evangelia Samara, Rui F. Pinto, Jasmina Magdalenic +6
In this study, we focus on improving EUHFORIA (European Heliospheric Forecasting Information Asset), a recently developed 3D MHD space weather prediction tool. EUHFORIA consists of…
Combining MHD and kinetic modelling of solar flares
M. Gordovskyy, P. K. Browning, R. F. Pinto
Solar flares are explosive events in the solar corona, representing fast conversion of magnetic energy into thermal and kinetic energy, and hence radiation, due to magnetic reconne…
The influence of the magnetic topology on the braking of sun-like stars
Victor Réville, Allan Sacha Brun, Sean Matt +2
Stellar winds are thought to be the main process responsible for the spin down of main-sequence stars. The extraction of angular momentum by a magnetized wind has been studied for…
Flux emergence in a magnetized convection zone
R. F. Pinto, A. S. Brun
We study the influence of a dynamo magnetic field on the buoyant rise and emergence of twisted magnetic flux-ropes, and their influence on the global external magnetic field. We ra…
Coupling the solar surface and the corona: coronal rotation, Alfvén wave-driven polar plumes
R. F. Pinto, R. Grappin, M. Velli +1
The dynamical response of the solar corona to surface and sub-surface perturbations depends on the chromospheric stratification, and specifically on how efficiently these layers re…
On the origin of the 1/f spectrum in the solar wind magnetic field
A. Verdini, R. Grappin, R. Pinto +1
We present a mechanism for the formation of the low frequency 1/f magnetic spectrum based on numerical solutions of a shell reduced-MHD model of the turbulent dynamics inside the s…
Coronal Inflows and Giant Polar Plumes
R. Pinto, R. Grappin, J. Leorat
We present the first results of simulations of giant polar plumes and coronal flows. We use a 2.5D axisymmetric MHD numerical model of an isothermal corona and slow solar wind. A p…
