X-ray and ultraviolet (UV) observations of the outer solar atmosphere have been used for
many decades to measure the fundamental parameters of the solar plasma. This review …

Modern observatories have revealed the ubiquitous presence of magnetohydrodynamic
waves in the solar corona. The propagating waves (in contrast to the standing waves) are …

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 …

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 …

One of the most important early results from the Parker Solar Probe (PSP) is the ubiquitous
presence of magnetic switchbacks, whose origin is under debate. Using a three-dimensional …

Abstract During Parker Solar Probe's first orbit, the solar wind plasma was observed in situ
closer than ever before, the perihelion on 2018 November 6 revealing a flow that is …

Abstract The Parker Solar Probe (PSP) achieved its first orbit perihelion on 2018 November
6, reaching a heliocentric distance of about 0.165 au (35.55 R⊙). Here, we study the …

We present three-dimensional direct numerical simulations and an analytic model of
reflection-driven magnetohydrodynamic (MHD) turbulence in the solar wind. Our simulations …

We propose a turbulence-driven solar wind model for a fast solar wind flow in an open
coronal hole where the solar wind flow and the magnetic field are highly aligned. We …

Abstract Motivated by recent Parker Solar Probe (PSP) observations of" switchbacks"(abrupt,
large-amplitude reversals in the radial magnetic field, which exhibit Alfvénic correlations) …
