What happens during the T Tauri phase?
It begins life as a protostar still enshrouded in its natal molecular cloud, accreting new material and developing a proto-planetary disc. 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.
Why are T Tauri stars variable?
The random variations (with time-scales from minutes to years) may be caused by instabilities in the accretion disk (which also produce the ‘bullets’ of material seen in the jet of HH-30 above), flares on the stellar surface, or simple obscuration by nearby dust and gas clouds.
What happened to the sun when it went through the T Tauri stage?
A T Tauri stage for the Solar System would be one means by which the angular momentum of the contracting Sun was transferred to the protoplanetary disc and hence, eventually to the planets.
What is a characteristic of T Tauri stars?
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.
What is the color of T Tauri?
T Tauri Facts T Tauri is not part of the Taurus constellation outline but is within the borders of the constellation. Based on the spectral type (K0IIIe) of the star, the T Tauri colour is orange to red . T Tauri is a Binary or Multiple star system.
How hot is Tauri?
4,646 KT Tauri / Surface temperature
What is at Tauri star quizlet?
T Tauri stars are a class of variable stars named after their prototype – T Tauri. They are found near molecular clouds and identified by their optical variability and strong chromospheric lines. T tauri wind.
Was the Sun a T Tauri?
T Tauri stars are a class of variable stars, named for their prototype T Tauri, discovered in 1852. T Tauri stars have been known for decades as relatively normal, medium-sized, extremely young main-sequence stars. At one point, some 4.5 billion years ago, our Sun was a T Tauri star.
