Robust temperatures and luminosities of cores in 1000 high-mass cluster-forming regions with ALMAGAL

Abstract: In this contribution, I will show the intricate picture at 50 au of the IRAS 4A2 protostar within the ALMA LP FAUST. This protostar hosts a compact (below 100 au) hot (above 100 K) dense (above 10$^7$ cm$^{-3}$) region rich in prebiotic complex organic molecules, and launches a large bipolar jet. The combination of high angular (scales of 50 au) and spectral resolution (below 0.5 km/s) observations with multiline radiative transfer analysis, revealed the various component of the inner regions of the system: a stratified chemical and physical structure and a wide disk wind.
