High Time Resolution Photometry of Red Dwarf Flare Stars III. The Most Rapid and Faintest Observed Stellar Flares; their Physics and Statistics [PDF]
AbstractHigh time resolution monitoring of the UV Cet type flare stars has enabled as to detect flares with total duration of a few seconds and with energy output comparable to solar subflares. We find that the time scales of decay for such flares correspond to recombination times of optically thin gas or to cooling times of optically thick gas heated ...

An abundance study of red-giant-branch stars in the Hercules dwarf spheroidal galaxy [PDF]
Context. Dwarf spheroidal galaxies are some of the most metal-poor, and least luminous objects known. Detailed elemental abundance analysis of stars in these faint objects is key to our understanding of star formation and chemical enrichment in the early

Story2Board: A Training‐Free Approach for Expressive Visual Storytelling
Abstract We present Story2Board, a training‐free framework for expressive storyboard generation from natural language. Existing methods narrowly focus on subject identity, overlooking key aspects of visual storytelling such as spatial composition, background evolution, and narrative pacing.

ABSTRACT Examination and sequencing of Psychidae specimens from Australia confirm that the genus Amatissa Walker, 1862 is present in this region, extending its known distribution. The first multispecies phylogeny of Amatissa is presented based on mitochondrial sequence data.

‘A simple outgrowth of the democracy’: Women's Suffrage, Democracy, and the Third Reform Act
Abstract The 1884 Reform Act was a landmark in the history of British democracy, creating almost three million voters and bringing farm labourers, miners, and shipworkers cascading onto the register. Yet 1884 was also a moment of democratic exclusion.

Flare stars across the H-R diagram [PDF]
Flare stars appear to be as common among the hottest stars as among the coolest. Starspots, which are closely associated with flares, are likewise common among stars of all spectral types.

Acoustic waves, hydromagnetic effect, and convective instability due to molecular dissociation are considered as mechanisms for flare activity in M dwarf stars. The first mechanism does not appear to be significant.
