T Tauri stars therefore represent an intermediate stage between real protostars (e.g. YY Orionis stars) and low-mass main sequence (hydrogen burning) stars like the Sun. The nearest T Tauri stars to us are in the Taurus and ρ-Ophiuchus molecular clouds, both about 400 light years away. The prototypical T Tauri star – T Tauri itself – is part of a close binary system with a smaller, fainter companion. This is visible in the high resolution infrared image below.

The star has a mass of 1.16 solar masses and has grown to a size of 44.13 solar radii. With a surface temperature of 3,900 K, it shines with a luminosity 439 times that of the Sun, with a lot of its energy output being in the invisible infrared.
Based on the spectral type (K0IIIe) of the star, the star's colour is orange to red . The star can not be seen by the naked eye, you need a telescope to see T Tauri is a variable star in the constellation Taurus, the prototype of the T Tauri stars.It was discovered in October 1852 by John Russell Hind.T Tauri appears from Earth amongst the Hyades cluster, not far from ε Tauri; but it is actually 420 light years behind it and was not formed with the rest of them. T Tauri stars therefore represent an intermediate stage between real protostars (e.g.

They are not a particular star and can vary in size depending on the propagator star and the amount of matter around it. 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 low-mass main sequence star like the Sun. T Tauri stars are found only in nebulae or very young clusters, have low-temperature ( They range in mass from 15 to 90 solar masses and burn very brightly indeed, with a surface temperature reaching 52,000 K so appear very blue. They are very short lived with lifetimes of 1 - 10 million years, ending in supernova. Class O star systems rarely contain terrestrial bodies.
