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 …

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

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 …

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 …

Abstract Parker Solar Probe (PSP) data recorded within a heliocentric radial distance of 0.3
au have revealed a magnetic field dominated by Alfvénic structures that undergo large local …

Aims. This paper describes the Polarimetric and Helioseismic Imager on the Solar Orbiter
mission (SO/PHI), the first magnetograph and helioseismology instrument to observe the …

Drawing connections between heliospheric spacecraft and solar wind sources is a vital step
in understanding the evolution of the solar corona into the solar wind and contextualizing in …

Context. Solar wind backmap** is a technique employed to connect in situ measurements
of heliospheric plasma structures to their origin near the Sun. The most widely used method …
