A star cluster is a large group of coeval stars formed from the same molecular cloud.


Working:

A group of stars nearby which appear to be coeval.


I work with massive stars and feedback observational, and thus unavoidably work with stellar clusters a lot

Clusters are one of the oldest structures, understanding them helps us understand galaxy formation

I think that a star cluster would be either a group of stars that are gravitationally bound and/or participating in significant feedback with each other.
