Li production by stellar flares in young open clusters
, 2008 The correlation observed between the Li abundance and surface activity of young cool stars is not explained by current stellar evolution models. We study the possibility that this correlation arises from significant in situ production of Li by solar-like

Flares on active M-type stars observed with XMM-Newton and Chandra.
, 2007 M-type red dwarfs are among the most active stars. Their light curves display random variability of rapid increase and gradual decrease in emission.

Solar and stellar flares: implication on the similar physical mechanisms
, 2016 In this talk, we briefly reviewed and compared various aspects of solar and stellar flares. The results imply the similar physical mechanisms of the two phenomena.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Analyzing the Morphology of Late-phase Stellar Flares from G-, K-, and M-type Stars
The Astrophysical JournalStellar flares occasionally present a peak-bump light-curve morphology, consisting of an initial impulsive phase followed by a gradual late phase.

Multichannel spectrophotometry of stellar flares
The Astrophysical Journal, 1980 Stellar flares have been observed using the 32 channel spectrophotometer on the 5 m telescope. Net flare fluxes in the region 3200-7000 A are presented. A simple model of blackbody radiation and hydrogen recombination emission appears to fit the continuum points well.
