Term: Classical T Tauri stars

A T Tauri star in which accretion from a circumstellar disk is responsible for ultraviolet and infrared excess emission and for a moderate to strong emission line spectrum superimposed on the photospheric spectrum. Classical T Tauri stars probably evolve into weak-line T Tauri stars when their disks are fully accreted by the stars.
