PRODIGE -- envelope to disk with NOEMA VIII. Sulfur oxides trace a shock caused by a streamer in the inner envelope of a protostar
María 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…
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…

P. C. Cortes, J. E. Pineda, T. -H. Hsieh +22
We present the first results from the ALMA Perseus Polarization Survey (ALPPS), focusing on the magnetic field in the SVS13A circumbinary disk. The dataset includes full-Stokes dus…
Chemical segregation analysed with unsupervised clustering
K. Giers, S. Spezzano, Y. Lin +3
Molecular emission is a powerful tool for studying the physical and chemical structures of dense cores. The distribution and abundance of different molecules provide information on…
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…
Dense clumps survive in the vicinity of R136 in 30 Doradus
M. T. Valdivia-Mena, M. Rubio, V. M. Kalari +5
Context: The young massive cluster R136 at the center of 30 Doradus (30 Dor) in the Large Magellanic Cloud (LMC) generates a cavity in the surrounding molecular cloud. However, the…
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…
Resolved Gas Temperatures and 12C/13C ratios in SVS13A from ALMA Observations of CH3CN and CH3-13-CN
T. -H. Hsieh, J. E. Pineda, D. M. Segura-Cox +11
Context. Multiple systems are common in field stars, and the frequency is found to be higher in early evolutionary stages. Thus, the study of young multiple systems during the embe…
PRODIGE -- envelope to disk with NOEMA. IV. An infalling gas bridge surrounding two Class 0/I systems in L1448N
C. Gieser, J. E. Pineda, D. M. Segura-Cox +13
Context. The formation of stars has been subject to extensive studies in the past decades from molecular cloud to protoplanetary disk scales. It is still not fully understood how t…
Probing the Physics of Star-Formation (ProPStar) III. No evidence for dissipation of turbulence down to 20 mpc (4 000 au) scale
Jaime E. Pineda, Juan D. Soler, Stella Offner +14
Context. Turbulence is a key component of molecular cloud structure. It is usually described by a cascade of energy down to the dissipation scale. The power spectrum for subsonic i…
PRODIGE -- Planet-forming disks in Taurus with NOEMA
R. Franceschi, Th. Henning, G. V. Smirnov-Pinchukov +17
We aim to constrain the gas density and temperature distributions as well as gas masses in several T Tauri protoplanetary disks located in Taurus. We use the 12CO, 13CO, and C18O (…
Probing the Physics of Star-Formation (ProPStar): II. The first systematic search for streamers toward protostars
María Teresa Valdivia-Mena, Jaime E. Pineda, Paola Caselli +9
The detection of narrow channels of accretion toward protostellar disks, known as streamers, have increased in number in the last few years. However, it is unclear if streamers are…
PRODIGE -- Envelope to Disk with NOEMA III. The origin of complex organic molecule emission in SVS13A
T. -H. Hsieh, J. E. Pineda, D. M. Segura-Cox +18
Complex Organic Molecules (COMs) have been found toward low-mass protostars but the origins of the COM emission are still unclear. It can be associated with, for example, hot corin…
