FAUST. XXVIII. High-Resolution ALMA Observations of Class 0/I Disks: Structure, Optical Depths, and Temperatures
M. J. Maureira, J. E. Pineda, H. B. Liu +22
We present high-resolution (~7.5 au) ALMA observations at 1.3 and 3 mm of 16 disks around Class 0/I protostars across multiple star-forming regions and a variety of multiplicities,…
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 XXIV. Large dust grains in the protostellar outflow cavity walls of the Class I binary L1551 IRS5
G. Sabatini, E. Bianchi, C. J. Chandler +19
Planet formation around young stars requires the growth of interstellar dust grains from mm-sized particles to km-sized planetesimals. Numerical simulations have shown that large (…
FAUST XXV. A potential new molecular outflow in [BHB2007] 11
A. MartÃnez-Henares, I. Jiménez-Serra, C. Vastel +26
During the early stages of star formation, accretion processes such as infall from the envelope and molecular streamers, and ejection of matter through winds and jets take place si…
FAUST-XXII. Deuteration in the VLA1623-2417 protostellar hot-corinos, cavities, and streamers
S. Mercimek, C. Codella, L. Podio +13
The study of deuterium fractionation is a valuable tool for reconstructing our chemical history from the early prestellar stages to the formation of planets. In the context of the…
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…
