FAUST XXVI. The dust opacity spectral indices of protostellar envelopes bridge the gap between interstellar medium and disks
Luca Cacciapuoti, L. Testi, A. J. Maury +36
The sub-millimetre dust opacity spectral index is a critical observable to constrain dust properties, such as the maximum grain size of an observed dust population. It has been wid…

FAUST XX. The chemical structure and temperature profile of the IRAS 4A2 hot corino at 20-50 au
J. Frediani, M. De Simone, L. Testi +20
Young low-mass protostars often possess hot corinos, compact, hot and dense regions bright in interstellar Complex Organic Molecules (iCOMs). Besides of their prebiotic role, iCOMs…
