Active nests at solar maximum: How nested flux emergence dominated flaring activity and structured the heliosphere

Adam J. Finley, Allan Sacha Brun, Antoine Strugarek +5

Multi-viewpoint observations from near-Earth satellites and ESA's Solar Orbiter enable a global view of the Sun. This continuous coverage is essential for characterising active nes…

A prolific solar flare factory. Nearly continuous monitoring of an active region nest with Solar Orbiter

Adam J. Finley, Allan Sacha Brun, Antoine Strugarek +1

The properties of active region nests, which are locations on the Sun with recurring flux emergence, are poorly constrained by observations from Earth alone. ESA's Solar Orbiter no…

Magnetic connectivity from the Sun to the Earth with MHD models I. Impact of the magnetic modelling for connectivity validation

Silke Kennis, Barbara Perri, Stefaan Poedts

This article discusses the magnetic connectivity between the Sun and the Earth, which is essential for understanding solar wind and space weather events. Due to limited direct obse…

Impact of the solar activity on the propagation of ICMEs: Simulations of hydro, magnetic and median ICMEs at minimum and maximum of activity

Barbara Perri, Brigitte Schmieder, Pascal Démoulin +2

The propagation of Interplanetary Coronal Mass Ejections (ICMEs) in the heliosphere is influenced by many physical phenomena, related to the internal structure of the ICME and its…

COCONUT, a novel fast-converging MHD model for solar corona simulations: II. Assessing the impact of the input magnetic map on space-weather forecasting at minimum of activity

Barbara Perri, Blazej Kuzma, Michaela Brchnelova +5

This paper is dedicated to the new implicit unstructured coronal code COCONUT, which aims at providing fast and accurate inputs for space weather forecast as an alternative to empi…

To E or not to E: Numerical Nuances of Global Coronal Models

Michaela Brchnelova, Błażej Kuźma, Barbara Perri +2

In the recent years, global coronal models have experienced an ongoing increase in popularity as tools for forecasting solar weather. Within the domain of up to 21.5Rsun, magnetohy…
