The corona is a layer of hot plasma that surrounds the Sun, traces out its complex magnetic
field, and ultimately expands into interplanetary space as the supersonic solar wind …

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 …

Particles are accelerated to very high, non-thermal energies in solar and space plasma
environments. While energy spectra of accelerated electrons often exhibit a power law, it …

Quasi‐thermal noise spectroscopy is an efficient tool for measuring in situ macroscopic
plasma properties in space, using a passive wave receiver at the ports of an electric …

In this work, we combined AWSoM's nonequilibrium ionization (NEI) calculations from
Szente et al. with the synthetic spectral computations of SPECTRUM to predict …

Collisionless and weakly collisional plasmas often exhibit non-thermal quasi-equilibria.
Among these quasi-equilibria, distributions with power-law tails are ubiquitous. It is shown …

The observation of the high-temperature (≳ 10 MK) Fe xxi 1354.1 Å line with the Interface
Region Imaging Spectrograph has provided significant insights into the chromospheric …

Abstract The Solar X-ray Monitor (abbreviated as XSM) on board India's Chandrayaan-2
mission is designed to carry out broadband spectroscopy of the Sun from lunar orbit. It …

Abstract The Ecliptic poles Stellar Survey (EclipSS; 2018–2019) collected Hubble Space
Telescope/Cosmic Origins Spectrograph (COS) 1150–1420 Å spectra of 49 FGK dwarfs at …

Solar flares are 3D phenomena, but modeling a flare in 3D, including many of the important
processes in the chromosphere, is a computational challenge. Accurately modeling the …
