title: Infrared Stars: The interaction between stars and interstellar clouds produces "infrared stars" of two different kinds.
abstract: Our searches for very cool stars have revealed three kinds of objects: very cool Mira stars, perhaps cooler than any of this type previously known; extremely dense interstellar clouds, more dense than any known heretofore; and, probably, cool circumstellar clouds that may be planetary systems in an early stage of formation.
