Molecular and Atomic Gas Associated with the Gamma Ray Supernova Remnant RCW 103
H. Inoue, Y. Asano, R. G. Bhuvana +15
We present a study of the interstellar molecular and atomic gas associated with the gamma-ray supernova remnant (SNR) RCW 103 using the Mopra CO( = 1-0), Atacama Large Mi…
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…
A framework for incorporating binding energy distribution in gas-ice astrochemical models
Kenji Furuya
One of the most serious limitations of current astrochemical models with the rate equation (RE) approach is that only a single type of binding site is considered in grain surface c…
Outflow Driven by a Protoplanet Embedded in the TW Hya Disk
Tomohiro C. Yoshida, Hideko Nomura, Charles J. Law +4
Gas giant planets are formed by gas accretion onto planetary cores in protoplanetary disks. However, direct evidence of this process is still lacking, limiting our understanding of…
Carbon Isotope Fractionation of Complex Organic Molecules in Star-Forming Cores
Ryota Ichimura, Hideko Nomura, Kenji Furuya
Recent high-resolution and sensitivity ALMA observations have unveiled the carbon isotope ratios (C/C) of Complex Organic Molecules (COMs) in a low-mass protostellar…
Deep Search for Phosphine in a Prestellar Core
Kenji Furuya, Takashi Shimonishi
Understanding in which chemical forms phosphorus exists in star- and planet-forming regions and how phosphorus is delivered to planets are of great interest from the viewpoint of t…
Effect of time-varying X-ray emission from stellar flares on the ionization of protoplanetary disks
Haruka Washinoue, Shinsuke Takasao, Kenji Furuya
X-rays have significant impacts on cold, weakly ionized protoplanetary disks by increasing the ionization rate and driving chemical reactions. Stellar flares are explosions that em…
Carbon isotope chemistry in protoplanetary disks: Effects of C/O ratios
Seokho Lee, Hideko Nomura, Kenji Furuya
Carbon isotope fractionation of CO has been reported in the disk around TW Hya,where elemental carbon is more abundant than elemental oxygen ([C/O]> 1). We investigate…
The First Spatially-resolved Detection of CN in a Protoplanetary Disk and Evidence for Complex Carbon Isotope Fractionation
Tomohiro C. Yoshida, Hideko Nomura, Kenji Furuya +7
Recent measurements of carbon isotope ratios in both protoplanetary disks and exoplanet atmospheres have suggested a possible transfer of significant carbon isotope fractionation f…
ALMA Observations of Supernova Remnant N49 in the Large Magellanic Cloud. II. Non-LTE Analysis of Shock-heated Molecular Clouds
H. Sano, Y. Yamane, J. Th. van Loon +28
We present the first compelling evidence of shock-heated molecular clouds associated with the supernova remnant (SNR) N49 in the Large Magellanic Cloud (LMC). Using CO( =…
