One characteristic trait of space plasmas is the multi-scale dynamics resulting from non-
linear transfers and conversions of various forms of energy. Routinely evidenced in a range …

Aims. The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter is a hard X-ray
imaging spectrometer, which covers the energy range from 4 to 150 keV. STIX observes …

Aims. Solar Orbiter, the first mission of ESA's Cosmic Vision 2015–2025 programme and a
mission of international collaboration between ESA and NASA, will explore the Sun and …

A clear understanding of the nature of the pre-eruptive magnetic field configurations of
Coronal Mass Ejections (CMEs) is required for understanding and eventually predicting …

After decades of observations of solar energetic particles from space-based observatories,
relevant questions on particle injection, transport, and acceleration remain open. To address …

Coronal holes are areas on the Sun with open magnetic field lines. They are a source region
of the solar wind, but how the wind emerges from coronal holes is not known. We observed …

Context. The Extreme Ultraviolet Imager (EUI) is part of the remote sensing instrument
package of the ESA/NASA Solar Orbiter mission that will explore the inner heliosphere and …

The ambient solar wind that fills the heliosphere originates from multiple sources in the solar
corona and is highly structured. It is often described as high-speed, relatively homogeneous …

Aims. The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-
resolution imaging spectrometer operating at extreme ultraviolet wavelengths. In this paper …

The Solar Orbiter mission seeks to make connections between the physical processes
occurring at the Sun or in the solar corona and the nature of the solar wind created by those …
