Evidence for Sympathetic Flaring in TESS Data
The Astrophysical JournalMost flares on the Sun occur at random, but there is a small percentage of “sympathetic flaring”—the triggering of one flare by another. Previously there had been no widespread confirmation of sympathetic flares on other stars. In this work, we developed

Solar Neighborhood Flare Stars – a Review [PDF]
Symposium - International Astronomical Union, 1975 Since Gershberg's (1970a) very thorough review of the subject, numerous papers dealing with the collective properties of flare stars have appeared (Petit, 1970; Kunkel, 1970d, 1973; Ambartsumian and Mirzoyan, 1971; Gurzadyan, 1971; Oskanian and Terebizh, 1971a, b; Gershberg, 1972; Veeder, 1973).

The Primary Flare Following a Stellar Collision in a Galactic Nucleus
The Astrophysical Journal LettersHigh-velocity stellar collisions near supermassive black holes may result in a complete disruption of the stars. The initial disruption can have energies on par with supernovae and power a very fast transient.

Kepler super-flare stars: what are they?
, 2014 The Kepler mission has led to the serendipitous discovery of a significant number of `super flares' - white light flares with energies between 10^33 erg and 10^36 erg - on solar-type stars.

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.

New Approach to Superflare Energy Determination
The Astrophysical Journal LettersWe present a new method for estimating the total energy radiated by stellar flares in broadband continua, which assumes a constant emitting area but incorporates a time-dependent temperature evolution.

The Astronomical Journal, 1974 At least ten of the known UV Ceti-type flare stars in the solar neighborhood have old disk space motions. Five others have large space motions and are probably also members of the old disk population. The existence of flare stars with old disk space motions and also the existence of some flare stars below the main sequence complicates the picture of ...

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets
Advanced Materials Technologies, EarlyView.This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...
