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. T-Tauri stars (the 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 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. The protostar at first only has about 1% of its final mass. But the envelope of the star continues to grow as infalling material is accreted.

T tauri stage

A star start off as clouds of dust and gas before something starts the process of turning that nebula into a star. Describe how the T Tauri star stage in the life of a low-mass star can lead to the formation of a Herbig-Haro (H-H) object. +2. Answers (1) Rashad Park 19 March, 08:38. 0. When stellar wind blows high speed material away from the protostar and they collide with a denser mass of gas it excites the atoms causing them to emit light.

The grains may eventually coagulate into kilometer-sized planetesimals. T Tauri stars take after their prototype T Tauri.

If the body has sufficient mass, the collapsing gas and dust burn hotter, Mar 13, 2009 this stage, all stars of later spectral type are termed classical T Tauri stars ( CTTS); strictly speaking both During the T Tauri phase it already.
