Validation of computed extreme ultraviolet emission spectra during solar flares [PDF]

open access: yesEarth, Planets and Space, 2021
X-rays and extreme ultraviolet (EUV) emissions from solar flares rapidly change the physical composition of the Earth’s thermosphere and ionosphere, thereby causing space weather phenomena such as communication failures.

Determination of Differential Emission Measure from Solar Extreme Ultraviolet Images [PDF]

open access: yesThe Astrophysical Journal Letters, 2018
Abstract The Atmospheric Imaging Assembly (AIA) on board the Solar Dynamic Observatory (SDO) has been providing high-cadence, high-resolution, full-disk UV-visible/extreme ultraviolet (EUV) images since 2010, with the best time coverage among all the solar missions.

First Detection of Solar Flare Emission in Mid-ultraviolet Balmer Continuum [PDF]

open access: yesThe Astrophysical Journal Letters, 2018
Abstract We present the first detection of solar flare emission at mid-ultraviolet wavelengths around 2000 Å by the channel 2 of the Large-Yield RAdiometer (LYRA) on board the PRoject for OnBoard Autonomy 2 mission. The flare (SOL20170906) was also observed in the channel 1 of LYRA centered at the H i Lyα line at 1216 Å, showing a clear ...

Solar-blind field-emission diamond ultraviolet detector [PDF]

open access: yesApplied Physics Letters, 2015
We report our studies on the responsivity of sulfur-doped diamond films to ultraviolet radiation using two types of device configurations: the planar configuration with electrodes directly on the diamond surface, and the electron field emission configuration with a bias electrode suspended above the diamond surface.

On the Doppler Shifts of Solar Ultraviolet Emission Lines

open access: yesThe Astrophysical Journal, 1999
We examine emission-line profiles observed with the Solar Ultraviolet Measurement of Emitted Radiation (SUMER) instrument during the roll of the SOHO spacecraft on 1997 March 20. SUMER data were acquired in selected wavelength bands including lines from the low chromosphere to the corona.

Extreme-ultraviolet and X-Ray Emission of Turbulent Solar Flare Loops [PDF]

open access: yesThe Astrophysical Journal Letters, 2019
Abstract Turbulence has been observed in flare loops and is believed to be crucial for the acceleration of particles and in the emission of X-ray photons in flares, but how the turbulence is produced is still an open question. A scenario proposed by Fang et al.

Self-powered mechanoluminescent elastomer for solar-blind ultraviolet emission [PDF]

open access: yesLight: Science & Applications
Flexible mechanoluminescence (ML) elastomers show significant potential for next-generation wearable electronics, artificial skin, advanced sensing, and human-machine interaction. However, their broader application has been hindered by challenges such as
