Statistical research into low-power solar flares. Main phase duration
Solar-Terrestrial Physics, 2017 This paper is a sequel to earlier papers on time parameters of solar flares in the Hα line. Using data from the International Flare Patrol, an electronic database of solar flares for the period 1972–2010 has been created.

Modeling Solar Energetic Neutral Atoms from Solar Flares and CME-driven Shocks
The Astrophysical Journal, 2023 We examine the production of energetic neutral atoms (ENAs) in solar flares and coronal mass ejection (CME)-driven shocks and their subsequent propagation to 1 au. Time profiles and fluence spectra of solar ENAs at 1 au are computed for two scenarios: (1)

No Evidence Supporting Flare Driven High-Frequency Global Oscillations
, 2012 The underlying physics that generates the excitations in the global low-frequency, < 5.3 mHz, solar acoustic power spectrum is a well known process that is attributed to solar convection; However, a definitive explanation as to what causes excitations in

COMPTEL gamma ray and neutron measurements of solar flares [PDF]
, 1993 COMPTEL on the Compton Gamma Ray Observatory has measured the flux of x‐rays and neutrons from several solar flares. These data have also been used to image the Sun in both forms of radiation.

A LARGE-SCALE SEARCH FOR EVIDENCE OF QUASI-PERIODIC PULSATIONS IN SOLAR FLARES [PDF]
, 2016 The nature of quasi-periodic pulsations (QPP) in solar flares is poorly constrained, and critically the general prevalence of such signals in solar flares is unknown.

A Parameter Study for Modeling Mg ii h and k Emission during Solar Flares [PDF]
, 2017 Solar flares show highly unusual spectra in which the thermodynamic conditions of the solar atmosphere are encoded. Current models are unable to fully reproduce the spectroscopic flare observations, especially the single-peaked spectral profiles of the ...

Three-dimensional magnetic reconnection and its application to solar flares [PDF]
Journal of Plasma Physics, 2016 Solar flares are powerful radiations occurring in the Sun’s atmosphere. They are powered by magnetic reconnection, a phenomenon that can convert magnetic energy into other forms of energy such as heat and kinetic energy, and which is believed to be ...

Two Types of Confined Solar Flares
Astrophysical Journal, 2019 With the aim of understanding the physical mechanisms of confined flares, we selected 18 confined flares during 2011–2017, and first classified them into two types based on their different dynamic properties and magnetic configurations. “Type I” confined

FlexMat, EarlyView.This paper presents a comprehensive review of radio frequency (RF)‐based wireless charging technologies for flexible electronics. In particular, we (i) provide an overview of wireless charging approaches, (ii) investigate the fundamental RF charging principles, covering rectenna design, impedance matching, RF‐to‐DC conversion, and power management, and
