T Tauri stars are young, low-mass stars that are still in the process of contracting and reaching the main sequence. They typically have strong stellar winds and are often associated with dusty disks of gas and dust, which may eventually form planets. These stars are named after the prototype star, T Tauri, located in the constellation Taurus.

What are T Tauri stars?

T Tauri stars are young, pre-main sequence stars that are typically less than a few million years old. They are characterized by their variability in brightness and are often surrounded by protoplanetary disks, which can lead to the formation of planets. These stars have not yet reached the stable hydrogen-burning phase of their life cycle and are still contracting and heating up. T Tauri stars provide valuable insights into the early stages of stellar and planetary formation.


When do stars become stars?

The dividing line is usually considered to be when the accretion process stops and the T tauri wind begins. This is probably approximately coincident with the beginning of lithium fusion (a T tauri star is not yet hot and dense enough for hydrogen fusion to start).


How big is T Tauri?

T Tauri is a variable star in the constellation Taurus.Unfortunately, there is no data at the moment as to it's size, probably because of the amount of stellar material still orbiting it.


What is the difference between stars and shooting stars?

First off, shooting stars aren`t actually stars. They`re actually pieces of space rock called meteors. When meteors enter Earth`s atmosphere, they burn up, producing bright lights as they move through the sky. That is, if it`s night. If it`s day, then you can`t see them light up. Meteors are so fast that people say they`re faster than a speeding bullet, hence the name ''shooting'' star.


What spectral class of stars are less common?

O, B, and A spectral class stars are less common than G, K, and M spectral class stars. These earlier spectral class stars are larger, hotter, and more massive, leading them to have shorter lifespans and therefore be less abundant in the galaxy.
