Structure and chemistry of cluster forming regions

Séminaire IPAG de Peter Schilke (Köln University), jeudi 11 juillet 2019 à 11h00, salle Manuel Forestini

A significant fraction of stars, including our sun, have formed in clusters containing high-mass stars. Yet, the low-mass population in such clusters remain poorly studied. I will present an analysis of ALMA observations of two high-mass star containing cluster regions, and discuss statistical properties of the clusters, such as the clump mass function, distances and sub-clumping. Particular emphasis is put on the discussion of biases, which cause a considerable uncertainty in the shape of the CMF. I will also touch upon the outflow content of these two regions, and on the chemical diversity.
