"Massive star formation observed at high spatial resolution"

Abstract:
High-mass star formation is known to proceed in a clustered mode at
relatively large distances. Hence high spatial resolution, specifially at
(sub)mm wavelength tracing the cold gas and dust in these regions, is
essential to disentangle the various physical and chemical processes
taking place. I will present recent results obtained with several
interferometers (SMA, PdBI and ATCA) toward young massive
star-forming regions from Infrared Dark Clouds to Hot Molecular
Cores discussing properties like (potential) disk signatures, density
structures, spectral energy distributions, fragmentation and chemical
differences.
