Isotopomer-Specific Carbon Isotope Ratio of Complex Organic Molecules in Star-Forming Cores
Ryota Ichimura, Hideko Nomura, Kenji Furuya +2
The recent observation of complex organic molecules (COMs) in interstellar ices by the James Webb Space Telescope (JWST), along with previous gas-phase detections, underscores the…
Pristine ices in a planet-forming disk revealed by heavy water
Margot Leemker, John J. Tobin, Stefano Facchini +4
Water is essential to our understanding of the planet-formation process and habitability on Earth. Although trace amounts of water are seen across all phases of star and planet for…
Winding Motion of Spirals in a Gravitationally Unstable Protoplanetary Disk
Tomohiro C. Yoshida, Hideko Nomura, Kiyoaki Doi +5
The discovery of wide-orbit giant exoplanets has posed a challenge to our conventional understanding of planet formation by coagulation of dust grains and planetesimals, and subseq…
Binding energy distributions of alcohols, thiols, and their precursors on interstellar water ice surfaces
Arghyadeb Roy, Ankan Das, Milan Sil +4
Binding energy (BE) is a critical parameter in astrochemical modeling, governing the retention of species on interstellar dust grains and their subsequent chemical evolution. Howev…
CO Adsorption Sites on Interstellar Water Ices Explored with Machine Learning Potentials. Binding energy distributions and snowline
Giulia M. Bovolenta, Germán Molpeceres, Kenji Furuya +2
Context. Carbon monoxide (CO) is arguably the most important molecule for interstellar organic chemistry. Its binding to amorphous solid water (ASW) ice regulates both diffusion an…
Dust Scattering Albedo at Millimeter-Wavelengths in the TW Hya Disk
Tomohiro C. Yoshida, Hideko Nomura, Takashi Tsukagoshi +3
Planetary bodies are formed by coagulation of solid dust grains in protoplanetary disks. Therefore, it is crucial to constrain the physical and chemical properties of the dust grai…
