T-Tauri and the pre-main-sequence
After my little journey around brown dwarfs I was able to capture a T-Tauri star last week. These stars are in the pre-main-sequence, as opposed to brown dwarfs who will never reach this phase.
This is V1331 Cygni, a “T Tauri” star in Cygnus, in the middle of dark nebula LDN981.
What makes this star special is the little nebulous ring surrounding it. This is believed to be a circumstellar accretion disk. Usually these young stars are hidden in a nebula but in this case we can clearly see the star thanks to a jet blowing away the dust that would otherwise block our view.
Circumstellar accretion disks are where planets and asteroids are born so we’re potentially witnessing the early days of a solar system.
