red dwarf
Let an agent describe red dwarfs by designation, mass, activity, planets and habitability claims, 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 red dwarfs by designation, mass, activity, planets and habitability claims, with sourced data.
A small, cool, low-mass main-sequence star of spectral type M (and late K), the most common type of star in the Milky Way, with very long lifetimes; Proxima Centauri is an example.
What it is for: The most common stars, hosts of many exoplanets.
It can be look up nearby red dwarfs; study flares and activity; search for planets; assess habitability carefully.
Distinguishing features
Low mass and cool
Most common star type
Lifetimes of trillions of years
Often flare-active
What it looks like
Faint reddish stars, mostly invisible to the naked eye.
Physical character
mass: about 0.08-0.6 solar masses
surface temperature: about 2300-3900 K
How it is recognised
Spectral type M dwarfs
Nearby examples such as Proxima Centauri
Red giants are very different
