T Tauri stars are thought to be young protostars. They are of spectral class G (or more generally F to M) and have about the same mass of the Sun - thus they are protostars that eventually become yellow dwarf main sequence stars. The Sun may well have begun life as a T Tauri star.

T Tauri star (plural T Tauri stars) Any of a class of young visible stars having optical variability; they are often surrounded by a protoplanetary disc. Related terms . T Tauri T Tauri stars comprise the youngest visible F, G, K and M spectral type stars (<2 M ☉). Their surface temperatures are similar to those of main-sequence stars of the same mass, but they are significantly more luminous because their radii are larger.

T-Tauri stars are pre-main sequence stars that are named after the first star to be discovered T-Tauri in the constellation of Taurus. They are a young star and one that is a variable star as it can vary its size over time. T Tauri stars are less than 10 million years old. A star begins its life as a protostar still enveloped in its molecular cloud. Over the years the newborn st Long-term homogeneous photometry for 35 classical T Tauri stars (CTTS) in the Taurus–Auriga star-forming region has been analyzed. Reliable effective temperatures, interstellar extinctions T Tauri stars (TTS) are a class of variable stars that are less than about ten million years old.
