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 …

Waves and oscillations have been observed in the Sun's atmosphere for over half a century.
While such phenomena have readily been observed across the entire electromagnetic …

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 …

Switchbacks are sudden, large radial deflections of the solar wind magnetic field, widely
revealed in interplanetary space by the Parker Solar Probe. The switchbacks' formation …

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 solar wind consists of continuous streams of charged particles that escape into the
heliosphere from the Sun, and is split into fast and slow components, with the fast wind …

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 …

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 …

In this work, we present an investigation of the wind in the solar corona that has been
initiated by observations of the resonantly scattered ultraviolet emission of the coronal …
