Most if not all newly formed stars have protoplanetary disks of gas & dust circling around them. If you go to Wikipedia’s page on protoplanetary disks:

https://en.wikipedia.org/wiki/Protoplanetary_disk

… you’ll see the famous 2014 image of HL Tauri.

 

I remember the day it was made public. I said to myself “There it is! Planets have to be forming in the gaps.” There are at least 7 gaps there, so it’s going to be a nice solar system eventually.
