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…

FAUST XIX. DCO in the outflow cavities of NGC\,1333 IRAS\,4A: recovering the physical structure of its original prestellar core

Layal Chahine, Cecilia Ceccarelli, Marta De Simone +25

Molecular deuteration is a powerful diagnostic tool for probing the physical conditions and chemical processes in astrophysical environments. In this work, we focus on formaldehyde…

Probing the physics of star formation (ProPStar): I. First resolved maps of the electron fraction and cosmic-ray ionization rate in NGC 1333

Jaime E. Pineda, Olli Sipilä, Dominique M. Segura-Cox +11

Electron fraction and cosmic-ray ionization rates (CRIR) in star-forming regions are important quantities in astrochemical modeling and are critical to the degree of coupling betwe…

An Interferometric View of H-MM1. I. Direct Observation of NH3 Depletion

Jaime E. Pineda, Jorma Harju, Paola Caselli +14

Spectral lines of ammonia, NH, are useful probes of the physical conditions in dense molecular cloud cores. In addition to advantages in spectroscopy, ammonia has also been sug…

FAUST III. Misaligned rotations of the envelope, outflow, and disks in the multiple protostellar system of VLA 16232417

Satoshi Ohashi, Claudio Codella, Nami Sakai +69

We report a study of the low-mass Class-0 multiple system VLA 1623AB in the Ophiuchus star-forming region, using HCO (), CS (), and CCH () lines as…

Dissecting the super-critical filaments embedded in the 0.5 pc subsonic region of Barnard 5

Anika Schmiedeke, Jaime E. Pineda, Paola Caselli +7

We characterize in detail the two ~0.3 pc long filamentary structures found within the subsonic region of Barnard 5. We use combined GBT and VLA observations of the molecular lines…

The CARMA-NRO Orion Survey: Filament Formation via Collision-Induced Magnetic Reconnection -- The Stick in Orion A

Shuo Kong, Volker Ossenkopf-Okada, Héctor G. Arce +13

A unique filament is identified in the {\it Herschel} maps of the Orion A giant molecular cloud. The filament, which, we name the Stick, is ruler-straight and at an early evolution…

A protostellar system fed by a streamer of 10,500 au length

Jaime E. Pineda, Dominique Segura-Cox, Paola Caselli +5

Binary formation is an important aspect of star formation. One possible route for close-in binary formation is disk fragmentation. Recent observations show small scale…
