Stellar Collisions in Young Clusters: Formation of (Very) Massive Stars?


In young star clusters, the density can be high enough and the velocity dispersion low enough for stars to collide and merge with a significant probability. This has been suggested as a possible way to build up the highmass portion of the stellar mass function and as a mechanism leading to the formation of one or two very massive stars (M∗ > 150M⊙) through… (More)
