FAUST XXXII. Chemically layered structures and ionisation in the disk and envelope of NGC 1333 IRAS 4C
Shota Notsu, Nami Sakai, Yichen Zhang +71
Recent molecular line observations with high spatial resolutions have revealed vertical chemical stratification in Class I/II disks (i.e. chemical composition changing with height…
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…
Chemical and Physical Characterization of the Isolated Protostellar Source CB68: FAUST. IV
Muneaki Imai, Yoko Oya, Brian Svoboda +1
Chemical diversity of low-mass protostellar sources has so far been recognized, and environmental effects are invoked as its origin. In this context, observations of isolated proto…
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…
The young protostellar disk in IRAS16293-2422 B is hot and shows signatures of gravitational instability
Joaquin Zamponi, María José Maureira, Bo Zhao +4
Deeply embedded protostars are actively fed from their surrounding envelopes through their protostellar disk. The physical structure of such early disks might be different from tha…
FAUST II. Discovery of a Secondary Outflow in IRAS 15398-3359: Variability in Outflow Direction during the Earliest Stage of Star Formation?
Yuki Okoda, Yoko Oya, Logan Francis +66
We have observed the very low-mass Class 0 protostar IRAS 15398-3359 at scales ranging from 50 au to 1800 au, as part of the ALMA Large Program FAUST. We uncover a linear feature,…
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…
ALMA observations of envelopes around first hydrostatic core candidates
Maria Jose Maureira, Hector G. Arce, Michael M. Dunham +4
We present ALMA 3 mm molecular line and continuum observations with a resolution of ~3.5" towards five first hydrostatic core (FHSC) candidates (L1451-mm, Per-bolo 58, Per-bolo 45,…
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…
Orbital and mass constraints of the young binary system IRAS 16293-2422 A
