DG Tauri System

Exoplanetary Scratchpad [SysBP Img]

DG Tauri is the first star found to have the pebbles thought to form terrestrial planets. A 2.5 MYO star 450 ly away with parsec scale jets coming from its poles, indicating its young age. The pebbles appear in a belt at Jupiter like distances.

My Reaction

So, we finally see some pebbles. They must not stick around for very long. The scale of its jets are astounding. I'm not sure why it was called DG Tauri B in the 1999 articles, and the 2015 ones drop the B.
