The Taurus-Auriga association, also known as the Taurus-Auriga molecular clouds (TAMC),[1] is a stellar association located at a distance of around 140 parsecs (420 ly) from Earth in the constellation of Taurus.[2] It is the nearest large star formation region (SFR) to Earth.[3] Despite the low and relatively diffused star formation rates of the association, the rate of star formation has been accelerating over the past few million years.[4]
It is adjacent to the Taurus-Auriga complex is the Perseus Molecular cloud.[2]
Stars
There has been 94 pre-main sequence stars which have been identified to be part of or probable members of the group.[5] The average star in the Taurus-Auriga association are around a million years old and include protostars to T Tauri stars.[3]
Some notable stars include HD 30171, V600 Auriga, 2MASS J04590305+3003004, V1298 Tauri and HD 281691. There are also two M-type stars that are accelerating from the association, 2MASS J04510713+1708468 and 2MASS J05240794+2542438.[6]
The association has no metal-rich stars, reinforcing the idea that old planet host stars form in the inner part of the galactic disk and migrate outward.[3] It also notably lacks stars of intermediate and high mass, but there might have been three B-type stars and two A-type stars detected. The B-type stars are HD 28929, HD 29763, and HD 28149, and the two A-type stars are HD 31305 and HD 26212.
