PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
MarÃa Teresa Valdivia-Mena, Jaime E. Pineda, Caroline Gieser +24
(Abridged) Recently, streamers have been observed causing shocks at the outer edge of protoplanetary disks. The study of sulfur-bearing species can help us to understand the physic…
FAUST XXIX. OCS line emission: a new method for measuring the luminosity of embedded protostars in binary systems
Guillaume Saury, Vittorio Bariosco, Cecilia Ceccarelli +19
The luminosity of embedded protostars is commonly measured via observations of the dust continuum spectral energy distribution from millimetre to infrared wavelengths. However, thi…
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,…
ANTIHEROES-PRODIGE: Quantifying the connection from envelope to disk with the IRAM 30m telescope and NOEMA I. Attack of the streamers: L1448N's fight for order in the chaos
C. Gieser, P. Caselli, D. M. Segura-Cox +19
Star formation is a hierarchical process ranging from molecular clouds down to individual protostars. In particular how infalling asymmetric structures, called streamers, deliverin…
PRODIGE VI -- Envelope to Disk with NOEMA: VI. The Missing Sulfur Problem
J. J. Miranzo-Pastor, A. Fuente, D. Navarro-Almaida +17
Determining the amount of sulfur in volatiles and refractories in the ISM remains one of the main problems in astrochemistry. The detection of HS ices, which are thought to be…
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…
