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…
The Green Bank Ammonia Survey: Data Release 2
Jaime E. Pineda, Rachel K. Friesen, Erik Rosolowsky +22
We present an overview of the final data release (DR2) from the Green Bank Ammonia Survey (GAS). GAS is a Large Program at the Green Bank Telescope to map all Gould Belt star-formi…
Asymmetric accretion through a streamer onto the pre-stellar core H-MM1
Spandan Choudhury, Jongsoo Kim, Paola Caselli +2
CONTEXT: Dense cores are thought to be isolated from the surrounding cloud. However, observations of streamers and subsonic material outside core boundaries challenges this idea. A…
Evidence for Jet/Outflow Shocks Heating the Environment Around the Class I Protostellar Source Elias 29: FAUST XXI
Yoko Oya, Eri Saiga, Anna Miotello +1
We have observed the late Class I protostellar source Elias~29 at a spatial-resolution of 70~au with the Atacama~Large~Millimeter/submillimeter~Array (ALMA) as part of the FAUST La…
Infall of material onto the filaments in Barnard 5
Spandan Choudhury, Jaime E. Pineda, Paola Caselli +3
Aims. We aim to study the structure and kinematics of the two filaments inside the subsonic core Barnard 5 in Perseus using high-resolution ( 2400 au) NH3 data and a multi…
Flow of gas detected from beyond the filaments to protostellar scales in Barnard 5
M. T. Valdivia-Mena, J. E. Pineda, D. M. Segura-Cox +7
The infall of gas from outside natal cores has proven to feed protostars after the main accretion phase (Class 0). This changes our view of star formation to a picture that include…
FAUST VII. Detection of A Hot Corino in the Prototypical Warm Carbon-Chain Chemistry Source IRAS 15398-3359
Yuki Okoda, Yoko Oya, Logan Francis +16
We have observed the low-mass protostellar source, IRAS 153983359, at a resolution of 0.2-0.3, as part of the Atacama Large Millimeter/Submillimeter Array Large Program…
Velocity-Coherent Substructure in TMC-1: Inflow and Fragmentation
Simon E. T. Smith, Rachel Friesen, Antoine Marchal +11
Filamentary structures have been found nearly ubiquitously in molecular clouds and yet their formation and evolution is still poorly understood. We examine a segment of Taurus Mole…
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…
Are massive dense clumps truly sub-virial? A new analysis using Gould Belt ammonia data
Ayushi Singh, Christopher D. Matzner, Rachel K. Friesen +21
Dynamical studies of dense structures within molecular clouds often conclude that the most massive clumps contain too little kinetic energy for virial equilibrium, unless they are…
Transition from Coherent Cores to Surrounding Cloud in L1688
Spandan Choudhury, Jaime E. Pineda, Paola Caselli +8
Stars form in cold dense cores showing subsonic velocity dispersions. The parental molecular clouds display higher temperatures and supersonic velocity dispersions. The transition…
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,…
FAUST I. The hot corino at the heart of the prototypical Class I protostar L1551 IRS5
E. Bianchi, C. J. Chandler, C. Ceccarelli +63
The study of hot corinos in Solar-like protostars has been so far mostly limited to the Class 0 phase, hampering our understanding of their origin and evolution. In addition, recen…
Ubiquitous supersonic component in L1688 coherent cores
Spandan Choudhury, Jaime E. Pineda, Paola Caselli +15
Context : Star formation takes place in cold dense cores in molecular clouds. Earlier observations have found that dense cores exhibit subsonic non-thermal velocity dispersions. In…
Turbulence, Coherence and Collapse: Three Phases for Core Evolution
Stella S. R. Offner, Josh Taylor, Carleen Markey +6
We study the formation, evolution and collapse of dense cores by tracking structures in a magnetohydrodynamic simulation of a star-forming cloud. We identify cores using the dendro…
