A red dwarf is a type of star described in the conventions of stellar classification as a small and relatively cool type M red star classified as a dwarf. (ST reference: Star Charts)

Specifics

Two-thirds of all stars in the galaxy are M-type stars. (Last Unicorn RPG module: Star Trek: The Original Series Core Game Book, Decipher RPG module: Narrator's Guide)

The red dwarf type M0 V has an average brightness 0.01 that of Sol and mass 0.3 that of Sol. Its habitable zone ranges from 0.08 to 0.13 AU, and its gravitational influence reaches 3.6 AU. The red dwarf type M5 V has an average brightness 0.001 that of Sol and mass 0.2 that of Sol. Its habitable zone ranges from 0.0025 to 0.042 AU, and its influence reaches 1.6 AU. The age of these star types ranges from 8 to 24 billion years. (Decipher RPG module: Worlds)

Red dwarf stars remain unchanged for most of their existence, whereas brown dwarfs continually grow cooler. (TLE novel: The Buried Age)

They burn slower than other classes of stars. (Last Unicorn RPG module: Star Trek: The Next Generation Core Game Book, Decipher RPG module: Narrator's Guide)

Animals evolving on planets orbiting dim red dwarfs are more likely to develop a sense of infrared vision. (Star Trek Adventures RPG module: The Sciences Division)

History

In 2281, several Warrantors of Peace were abandoned by Romulans on a planetoid in a red dwarf binary star system. The binaries were responsible for producing Earth-normal gravity and double shadows. (TOS novel: Dwellers in the Crucible)

In 2376 in system SY-911, the Genesis Wave transformed a yellow giant into a red dwarf. (TNG - The Genesis Wave novel: Book 1)

In 2370, energy from star within the Jenolan Dyson Sphere was drained through subspace into the sphere, aging the star into a red dwarf. (TNG novel: Dyson Sphere)

Alternate realities

In July 2374 of the First Splinter timeline, while tracking Juliana Tainer's homing beacon aboard Archeus, Data investigated the fourth planet in an unnamed system consisting of a main sequence yellow star, a red dwarf, and six planets. It was located 416.2 light years from where he first picked up the signal, not far from Orion. (TNG - Cold Equations novel: The Persistence of Memory)

In 2380, the gas giant Gorsach V appeared to be collapsing into a red dwarf, but instead it was drawn into a quantum fissure and disappeared. (TNG novel: Q & A)
