PRODIGE - envelope to disk with NOEMA: VII. (Complex) organic molecules in the NGC1333 IRAS4B1 outflow: A new laboratory for shock chemistry
Laura A. Busch, J. E. Pineda, P. Caselli +20
Shock chemistry is an excellent tool to shed light on the formation and destruction mechanisms of complex organic molecules (COMs). The L1157-mm outflow is the only low-mass protos…
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…
PRODIGE - envelope to disk with NOEMA: V. Low 12C/13C ratios for CH3OH and CH3CN in hot corinos
L. A. Busch, J. E. Pineda, O. Sipilä +15
The 12C/13C isotope ratio has been derived towards numerous cold clouds (20-50 K) and a couple protoplanetary disks and exoplanet atmospheres. However, direct measurements of this…
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 (…
