This star was T-Tauri. Nearby the star is the Hind Nebula, NGC 1555 whose brightness is linked to the variability of the T Tauri star. (A.A.V.S.O.) T-Tauri stars can rotate rapidly such as a day.

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. They represent an early stage in stellar evolution, having only recently been formed by the rapid gravitational condensation of interstellar gas and dust.

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. Analogs of T Tauri stars in the higher mass range (2–8 solar masses )—A and B spectral type pre–main-sequence stars , are called Herbig Ae/Be-type stars .

T tauri stage

This early stage lasts about 100 million years before nuclear fusion kicks in and it becomes a true star. As you might know, stars start out as vast Find out information about T-Tauri stage. A star, with mass from 0.5 to 2.5 solar masses, in an early stage of formation at which interaction with its associated nebulosity, as well as possible Explanation of T-Tauri stage T Tauri är en eruptiv variabel av T Tauri-typ i stjärnbilden Oxen. Stjärnan varierar oförutsägbart mellan magnitud +9,3 och 13,5 med en period av 2,81 dygn och är ett stjärnsystem som består av åtminstone tre stjärnor.

T tauri stage

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.
