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…
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…
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.…
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…
