The FIP and inverse FIP effects in solar and stellar coronae
We review our state of knowledge of coronal element abundance anomalies in the Sun and
stars. We concentrate on the first ionization potential (FIP) effect observed in the solar …

Origins of the ambient solar wind: implications for space weather
The Sun's outer atmosphere is heated to temperatures of millions of degrees, and solar
plasma flows out into interplanetary space at supersonic speeds. This paper reviews our …

Multi-source connectivity as the driver of solar wind variability in the heliosphere
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 …

Observation of a magnetic switchback in the solar corona
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 …

Solar UV and X-ray spectral diagnostics
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 …

Probing the physics of the solar atmosphere with the Multi-slit Solar Explorer (MUSE). I. Coronal heating
Abstract The Multi-slit Solar Explorer (MUSE) is a proposed mission composed of a multislit
extreme ultraviolet (EUV) spectrograph (in three spectral bands around 171 Å, 284 Å, and …

Turbulent generation of magnetic switchbacks in the Alfvénic solar wind
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 …

Persistent Doppler shift oscillations observed with Hinode/EIS in the solar corona: spectroscopic signatures of Alfvénic waves and recurring upflows
Using data obtained by the EUV Imaging Spectrometer on board Hinode, we have
performed a survey of obvious and persistent (without significant dam**) Doppler shift …

Observational evidence of S-web source of the slow solar wind
Abstract From 2022 March 18 to 21, NOAA Active Region (AR) 12967 was tracked
simultaneously by Solar Orbiter at 0.35 au and Hinode/EIS at Earth. During this period …

Full-Sun observations for identifying the source of the slow solar wind
Abstract Fast (> 700 km s− 1) and slow (~ 400 km s− 1) winds stream from the Sun,
permeate the heliosphere and influence the near-Earth environment. While the fast wind is …
