Magnetohydrodynamic plasma turbulence is believed to play a vital role in the production of energetic electrons during solar flares, and the nonthermal broadening of spectral lines is a key sign of this turbulence. Here, we determine how flare turbulence evolves in time and space using spectral profiles of Fe xxiv, Fe xxiii, and Fe xvi, observed by the Hinode/EUV Imaging Spectrometer. Maps of nonthermal velocity are created for times covering the X-ray rise, peak, and decay. For the first time… 


Spatially inhomogeneous acceleration of electrons in solar flares
The imaging spectroscopy capabilities of the Reuven Ramaty high energy solar spectroscopic imager (RHESSI) enable the examination of the accelerated electron distribution throughout a solar flare
The development of lower-atmosphere turbulence early in a solar flare
The first observational study of the onset and evolution of solar flare turbulence in the lower solar atmosphere on an unprecedented time scale of 1.7 s is presented, suggesting that turbulence partly heats the lower atmosphere.
Non-gaussian velocity distributions in solar flares from extreme ultraviolet lines: a possible diagnostic of ion acceleration
In a solar flare, a large fraction of the magnetic energy released is converted rapidly to the kinetic energy of non-thermal particles and bulk plasma motion. This will likely result in
Non-LTE Radiating Acoustic Shocks and CA II K2V Bright Points
We present, for the first time, a self-consistent solution of the time-dependent 1D equations of non-LTE radiation hydrodynamics in solar chromospheric conditions. The vertical propagation of
A Mechanism for Bulk Energization in the Impulsive Phase of Solar Flares: MHD Turbulent Cascade
We propose that the large production rate (approximately 10(exp 36)/s) of energetic electrons (greater than or approximately equal to 25 keV) required to account for the impulsive-phase hard X-ray
Plasma motions and non-thermal line broadening in flaring twisted coronal loops
Observation of coronal EUV spectral lines sensitive to different temperatures offers an opportunity to evaluate the thermal structure and flows in flaring atmospheres. This can be used to estimate
High-temperature differential emission measure and altitude variations in the temperature and density of solar flare coronal X-ray sources
The detailed knowledge of plasma heating and acceleration region properties presents a major observational challenge in solar flare physics. Using the Ramaty High Energy Solar Spectroscopic Imager
Spectroscopic Observations of Current Sheet Formation and Evolution
We report on the structure and evolution of a current sheet that formed in the wake of an eruptive X8.3 flare observed at the west limb of the Sun on September 10, 2017. Using observations from the
First evidence of non-Gaussian solar flare EUV spectral line profiles and accelerated non-thermal ion motion
The properties of solar flare plasma can be determined from the observation of optically thin lines. The emitting ion distribution determines the shape of the line, with an isothermal Maxwellian ion
Element Abundances in Solar Energetic Particles and the Solar Corona
This is a study of abundances of the elements He, C, N, O, Ne, Mg, Si, S, Ar, Ca, and Fe in solar energetic particles (SEPs) in the 2 – 15 MeV amu−1 region measured on the Wind spacecraft during 54
