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…
Structure of crystalline water ice formed through neon matrix sublimation under cryogenic and vacuum conditions
Reo Sato, So Taniguchi, Naoki Numadate +1
Ice I has three forms depending on the stacking arrangements of its layers: hexagonal ice Ih, cubic ice Ic, and stacking disordered ice Isd. Below ~60 K, amorphous water becomes me…
Multiple chemical tracers finally unveil the intricate NGC\,1333 IRAS\,4A outflow system. FAUST XVI
Layal Chahine, Cecilia Ceccarelli, Marta De Simone +54
The exploration of outflows in protobinary systems presents a challenging yet crucial endeavour, offering valuable insights into the dynamic interplay between protostars and their…
Direct Observation and Quantitative Measurement of OH Radical Desorption During the Ultraviolet Photolysis of Liquid Nonanoic Acid
Naoki Numadate, Shota Saito, Yuki Nojima +3
Ultraviolet (UV) photolysis of fatty acid surfactants which cover the surfaces of atmospheric liquid aerosols and are found in the oceans such as nonanoic acid (NA) has recently be…
Diffusion activation energy and desorption activation energy for astrochemically relevant species on water ice show no clear relation
Kenji Furuya, Tetsuya Hama, Yasuhiro Oba +3
The activation energy for desorption (Edes) and that for surface diffusion (Esd) of adsorbed molecules on dust grains are two of the most important parameters for the chemistry in…
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…
Infrared multiple-angle incidence resolution spectrometry for vapor-deposited amorphous water
Takumi Nagasawa, Naoki Numadate, Tetsuya Hama
Infrared (IR) multiple-angle incidence resolution spectrometry (IR-MAIRS) is a recently developed spectroscopic technique that combines oblique incidence transmission measurements…
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…
Transmission Electron Microscopy Study of the Morphology of Ices Composed of H2O, CO2, and CO on Refractory Grains
Akira Kouchi, Masashi Tsuge, Tetsuya Hama +15
It has been implicitly assumed that ices on grains in molecular clouds and proto planetary disks are formed by homogeneous layers regardless of their composition or crystallinity.…
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…
Interactions of Atomic and Molecular Hydrogen with a Diamond-like Carbon Surface: H2 Formation and Desorption
Masashi Tsuge, Tetsuya Hama, Yuki Kimura +2
The interactions of atomic and molecular hydrogen with bare interstellar dust grain surfaces are important for understanding H2 formation at relatively high temperatures (>20 K). W…
H ortho-para spin conversion on inhomogeneous grain surfaces
Kenji Furuya, Yuri Aikawa, Tetsuya Hama +1
We investigate the evolution of the ortho-to-para ratio of overall (gas + ice) H via the nuclear spin conversion on grain surfaces coated with water ice under physical conditio…
Adsorption energies of carbon, nitrogen, and oxygen atoms on the low-temperature amorphous water ice: A systematic estimation from quantum chemistry calculations
Takashi Shimonishi, Naoki Nakatani, Kenji Furuya +1
We propose a new simple computational model to estimate adsorption energies of atoms and molecules to low-temperature amorphous water ice, and we present the adsorption energies of…
Water Formation through a Quantum Tunneling Surface Reaction, OH + H2, at 10 K
Y. Oba, N. Watanabe, T. Hama +3
The present study experimentally demonstrated that solid H2O is formed through the surface reaction OH + H2 at 10 K. This is the first experimental evidence of solid H2O formation…
