Cluster-Formation Conditions and Star Formation Relations

Genevieve Parmentier , ARI

In this contribution, the connections between cluster-formation conditions, star formation relations and star cluster evolution are investigated. Star formation relations present a diversity of slopes whose physical interpretation requires a careful understanding of the data they represent. From the quadratic star formation relation of molecular clouds of the Solar neighbourhood to the linear star formation relation of distant molecular clumps of the Galactic disc, I shall discuss what these relations tell us and, also, what they do not tell us. With the local quadratic star formation relation supporting the hypothesis that star clusters form in centrally-concentrated molecular clumps with a constant star formation efficiency per free-fall time, we shall see what the consequences for cluster-formation conditions are, and how cluster-formation conditions propagate through star cluster evolution.
