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

Our understanding of the formation and evolution of the corona and the heliosphere is linked
to our capability of properly interpret the data from remote sensing and in-situ observations …

Context. The Solar Orbiter spacecraft will be equipped with a wide range of remote-sensing
(RS) and in situ (IS) instruments to record novel and unprecedented measurements of the …

Context. A complex and long-lasting solar eruption on 17 April 2021 produced a widespread
solar energetic particle (SEP) event that was observed by five longitudinally well-separated …

Aims. The Spectral Imaging of the Coronal Environment (SPICE) instrument is a high-

The main scientific goal of Solar Orbiter is to address the central question of
heliophysics:'how does the Sun create and control the heliosphere?'To achieve this goal …

Coronal loop oscillations are common phenomena in the solar corona, which are often
classified as decaying and decayless oscillations. Using the high-resolution observation …
