T Tau is only unsusual compared with most "T-Tauri stars" in that it has quite a high mass. Most "T-Tauri stars" are a solar mass or lower, and if found in young stellar clusters and associations with ages $<10$ Myr, you can see from the plot below that they would have higher luminosities than they end up with on the main sequence.

This review presents the main aspects of the body of knowledge on T Tauri variable stars, which are presumed to be young, gravitationally contracting low- mass 

A star start off as cloudsof dust and gas before something starts the process of turning that nebulainto a star. T Tauri stars take after their prototype T Tauri. This is a star that rests over 400 light years away and appears to sit in the Hyades star cluster in the constellation Taurus. T Tauri stars are named for the prototype of the class, T Tauri.

This newly released Hubble images shows the T Tauri star known as V1331 Cyg. With its helical appearance resembling a snail's shell, this reflection nebula 

They measured the temperature of the water vapor, which appeared to be 2000 K. T Tauri Star. [/caption] When a star is still in the earliest stages of formation, it doesn’t have enough temperature in its core to ignite fusion of hydrogen and helium. Instead, the star T Tauri stars are pre-main-sequence stars in the process of contracting to the main sequence along the Hayashi track, a luminosity-temperature relationship obeyed by infant stars of less than 3 solar masses in the pre-main-sequence phase of stellar evolution. T Tauri stars are the youngest visible F, G, K, M spectral type stars.

Named for the first of their type observed, T Tauri stars are variable stars which show both periodic and random fluctuations in their brightnesses. They are newly-formed (< 10 million years old) low to intermediate mass stars (< 3 solar masses ) with central temperatures too …

en T Tauri stars are Orion variables exhibiting characteristic fluorescent violet emission lines from singly ionized Iron (FeII) in their star spectra, and also emission from Lithium, a metal that usually is destroyed by the nuclear fusion in the stars.

T tauri star

An Interesting Neighborhood to Live In. The variable star T Tauri was discovered on an October night in 1852 by John Russell Hind. Hind, a noted asteroid hunter, is credited with having discovered 11 minor planets, as well as Nova Ophiuchi 1848 and R Leporis (also known as Hind's Crimson Star).

Weak-lined T Tauri stars are so named because we only see weak emission lines from them, and Naked T Tauri stars have little or no excess continuum or line emission at all. WTTS and NTTS are commonly observed in binary stars , so it was believed that perhaps the binary companions disrupt and dissipate each other's accretion disks. T Tauri stars are mostly between 10,000 and 10 million years in age; of low mass (0.5 to 3.0 M sol); surrounded by hot, dense envelopes; and losing mass via stellar winds with typical velocity of around 100 km/s. Many T Tauri stars are in binary systems.
