2021-04-09 · T Tauri star, any of a class of very young stars having a mass of the same order as that of the Sun. So called after a prototype identified in a bright region of gas and dust known as the Hind’s variable nebula, the T Tauri stars are characterized by erratic changes in brightness.

Sep 9, 2015 T Tauri stars are pre-main sequence stars in the process of contracting to the main sequence along the Hayashi track, a luminosity-temperature

T Tauri stars are named for the prototype of the class, T Tauri. These objects are pre-main sequence stars and have recently emerged from the opaque envelope of stellar formation. Having recently coalesced from their dusty and gaseous surroundings, these stars now become visible at optical wavelengths. A T Tauri star is a very young, lightweight star, less than 10 million years old and under 3 solar masses, that it still undergoing gravitational contraction; it represents an intermediate stage between a protostar and a mid-mass main sequence star like the Sun. T Tauri stars are found only in nebulas or very young clusters, have low-temperature (G to M type) spectra with strong emission lines As the protostar moves beyond stage 4, it becomes a T Tauri star, moving toward the main sequence. This path from stage 4 to 6 is known as the Hayashi track. Characterized by violent surface activity and strong protostellar winds.

So called after a prototype identified in a bright region of gas and dust known as the Hind’s variable nebula, the T Tauri stars are characterized by erratic changes in brightness. They represent an early stage in stellar evolution, having only recently been formed by the rapid gravitational condensation of interstellar gas and dust. The T Tauri wind — so named because of the young star currently in this stage—is a phenomenon indicative of the phase of stellar development between the accretion of material from the slowing rotating material of a solar nebula and the ignition of the hydrogen that has agglomerated into the protostar. Slowly, stellar winds and radiation blow away the surrounding shell of gas and dust, and the third stage, when the surrounding envelope has cleared, is called the T-Tauri phase.
