T-Tauri stars are young stars, not much older than about 10 million years old. Their mass is usually less than three solar masses. Not all stars will become T-Tauri stars, it is possible our star was once a T-Tauri star as it is conceivable that our star was once a T-Tauri star before becoming a Main Sequence star. T Tauri variable stars are pre main-sequence stars less than 10 million years.Music by Pixabay.com 2016-06-13 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.

This is a star that rests over 400 light years away and appears to sit in the Hyades star cluster in the constellation Taurus. This star type is variable in nature: we say that a star is variable when we observe changes in its luminosity – which is either caused by the star itself or when an object appears to eclipse it. 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. From a study of lithium abundances in 53 T Tauri stars, it has been found that lithium depletion varies strongly with size, suggesting that "lithium burning" by the P-P chain during the last highly convective and unstable stages during the later pre–main sequence phase of the Hayashi contraction may be one of the main sources of energy for T Tauri stars. Much of the work on disk timescales has been done on T Tauri stars, which are < 2 solar mass pre-main-sequence stars. They typically are < 5 Ma in age, accrete at ~ 10 –7 –10 –9 solar masses per year, and have disk masses of about 5 × 10 –3 solar masses and median disk/star mass ratios of 0.5% ( Mamajek, 2009 ), that is, about half that estimated for our own minimum mass solar nebula.

It is the prototype of the T Tauri stars. These young stars have surface temperatures similar to those of main-sequence stars of the same mass, but they are significantly more luminous because their radii are larger. 2021-04-09 · T Tauri stars are now generally recognized as young -- less than a few million years old -- sun-like stars still in the early stages of formation. To further complicate the picture, infrared observations indicate that T Tauri itself is part of a multiple star system. Surprisingly, due to a close gravitational pass near one of these stars, T Theoretical models and spectroscopic observations of newborn stars suggest that protoplantary disks have an inner “wall” at a distance set by the disk interaction with the star. Around T Tauri stars, the size of this disk hole is expected to be on a 0.1 au scale that is unresolved by current adaptive optics imaging, though some model-dependent constraints have been obtained by near-infrared interferometry.

Arwen Undómiel Their spectra show a higher lithium abundance than the Sun and other main-sequence stars because lithium is destroyed at temperatures above 2,500,000 K. From a study of lithium abundances in 53 T Tauri stars, it has been found that lithium depletion varies strongly with size, suggesting that "lithium burning" by the P-P chain during the last highly convective and unstable stages during the T Tauri Radius has been calculated as being 8.29 times bigger than the Sun.
