Question

Quizplus · Accepted Answer

A T Tauri wind is a rapid expulsion of the tenuous outer layers of a young star. This wind is formed when the young star's strong magnetic fields interact with the surrounding protoplanetary disk, launching material away from the star. It is an important process in the early stages of star formation, as it can help clear away the disk material and slow down the rate of accretion onto the star.
