(IAAC) Isserstedt stellar rings

Hi all,
I am actually reviewing an article written by a fellow amateur for Ciel
Extreme dedicated to this stellar groups: ring of stars thought to have an
origin in supernovae explosions.
If someone knows where I could find the list (that I suspect to be short)
of this potential rings, I would be happy to have it.
Any info and/or comments about the reality of such groupings are also
welcome. Thanks in advance,
Carpe noctem, Yann.
