flare star
Let an agent describe flare stars by star, flare properties, magnetic activity and implications for exoplanet habitability, with sourced data.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent describe flare stars by star, flare properties, magnetic activity and implications for exoplanet habitability, with sourced data.
A variable star, usually a red dwarf, that shows sudden, unpredictable increases in brightness due to magnetic flares, lasting minutes to hours; also called UV Ceti variables, with Proxima Centauri as a well-known example.
What it is for: Studying stellar magnetism and planetary environments.
It can be identify flare stars; describe flare energies and frequencies; relate flares to exoplanet habitability; find monitoring data.
Distinguishing features
Sudden magnetic flares
Mostly red dwarfs
Frequent activity when young
Relevant to planet habitability
What it looks like
Faint red stars that brighten suddenly, especially in ultraviolet and blue light.
How it is recognised
Rapid brightening and slower decay
Red dwarf spectral types
Novae are much larger explosions
