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…
Deuteration of Organic Molecules as a Probe of Starless Core and Filament Evolution in Barnard 10
Hanga Andras-Letanovszky, Yancy L. Shirley, Lucille J. Steffes +4
The deuterium fractionation of molecules in starless cores is sensitive to their dynamical histories, which recent magnetohydrodynamical simulations have shown to be extremely vari…
CMZoom IV. Incipient High-Mass Star Formation Throughout the Central Molecular Zone
H Perry Hatchfield, Cara Battersby, Ashley T. Barnes +15
In this work, we constrain the star-forming properties of all possible sites of incipient high-mass star formation in the Milky Way's Galactic Center. We identify dense structures…
Evidence of a Cloud-Cloud Collision from Overshooting Gas in the Galactic Center
Savannah R. Gramze, Adam Ginsburg, David S. Meier +4
The Milky Way is a barred spiral galaxy with "bar lanes" that bring gas towards the Galactic Center. Gas flowing along these bar lanes often overshoots, and instead of accreting on…
3D Radiative Transfer Modelling and Virial Analysis of Starless Cores in the B10 Region of the Taurus Molecular Cloud
Samantha Scibelli, Yancy Shirley, Anika Schmiedeke +4
Low-mass stars like our Sun begin their evolution within cold (10 K) and dense ( cm) cores of gas and dust. The physical structure of starless cores is best probe…
Tracking the ice mantle history in the Solar-type Protostars of NGC 1333 IRAS 4
Marta De Simone, Cecilia Ceccarelli, Claudio Codella +13
To understand the origin of the diversity observed in exoplanetary systems, it is crucial to characterize the early stages of their formation, represented by Solar-type protostars.…
FAUST VI. VLA 1623--2417 B: a new laboratory for astrochemistry around protostars on 50 au scale
C. Codella, A. López-Sepulcre, S. Ohashi +25
The ALMA interferometer, with its unprecedented combination of high-sensitivity and high-angular resolution, allows for (sub-)mm wavelength mapping of protostellar systems at Solar…
Hot methanol in the [BHB2007] 11 protobinary system: hot corino versus shock origin? : FAUST V
C. Vastel, F. Alves, C. Ceccarelli +63
Methanol is a ubiquitous species commonly found in the molecular interstellar medium. It is also a crucial seed species for the building-up of the chemical complexity in star formi…
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…
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…
ALMA-IMF I -- Investigating the origin of stellar masses: Introduction to the Large Program and first results
F. Motte, S. Bontemps, T. Csengeri +61
The ALMA-IMF Large Program imaged a total noncontiguous area of 53pc2, covering 15 extreme, nearby protoclusters of the Milky Way. They were selected to span relevant early protocl…
ALMA-IMF II -- investigating the origin of stellar masses: Continuum Images and Data Processing
A. Ginsburg, T. Csengeri, R. Galván-Madrid +49
We present the first data release of the ALMA-IMF Large Program, which covers the 12m-array continuum calibration and imaging. The ALMA-IMF Large Program is a survey of fifteen den…
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…
Hot Corinos Chemical Diversity: Myth or Reality?
Marta De Simone, Cecilia Ceccarelli, Claudio Codella +14
After almost 20 years of hunting, only about a dozen hot corinos, hot regions enriched in interstellar complex organic molecules (iCOMs), are known. Of them, many are binary system…
