On the 3D time evolution of the dust size distribution in protostellar envelopes
Maxime Lombart, Ugo Lebreuilly, Anaëlle Maury
Dust plays a fundamental role during protostellar collapse, disk and planet formation. Recent observations suggest that efficient dust growth may begin early, in the protostellar e…
Dissecting the dust distribution and polarization around two B213 young stellar objects with ALMA
Asako Sato, Anaëlle Maury, Josep M. Girart +4
The earliest stages of disk formation and dust evolution during the protostellar phase remain poorly constrained. Millimeter dust emission and its polarization provide key insights…
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…
Signatures of magnetic braking in Class 0 protostars ? Exploring the gas kinematics in magnetized models of low-mass star formation
N. Añez-Lopez, U. Lebreuilly, A. Maury +1
Only indirect evidence of the role of magnetic braking in regulating gravitational collapse and the formation of circumstellar disks was found from observational work, such as comp…
Multiple Outflows around a Single Protostar IRAS 153983359
Jinshi Sai, Hsi-Wei Yen, Masahiro N. Machida +4
We present the results of our mosaic observations of a single Class 0 protostar IRAS 153983359 with Atacama Compact Array (ACA) in the CO $J=2\mbox{-}1$ line. The new observatio…
Synthetic populations of protoplanetary disks. Impact of magnetic fields and radiative transfer
U. Lebreuilly, P. Hennebelle, T. Colman +10
Protostellar disks are the product of angular momentum conservation during the protostellar collapse. Understanding their formation is crucial because they are the birthplace of pl…
