Description

Although great progress has been made the last years on the shape of
the Stellar Mass Function and the dynamics of stellar clusters in more
evolved clusters, less is known on the earliest stages of star
formation. Here we present recent JWST observations in conjunction
with previous HST and VLT observations of a still forming star
cluster, identified by a large molecular infall. The sensitivity of JWST allows determining the IMF deep into the brown dwarf region and the long baseline available in combination with previous HST observations allows determination of the velocity dispersion down to a km/s. We discuss the
clustering, the velocity dispersion, and the Mass Function to low
masses in the cluster and the implications for massive star formation
and cluster formation.
