A T association is a stellar association (a loose group of stars of similar spectral class) that includes a lot of T-Tauri stars (TTSs). Some also include OB stars, and some are near molecular clouds that appear to be their source. An example T association is the Taurus-Auriga T association, which is the nearest to us, about 140 parsecs, thus of interest for observation.
