Different degrees of nitrogen and carbon depletion in the warm molecular layers of protoplanetary disks
Kenji Furuya, Seokho Lee, Hideko Nomura
Observations have revealed that the elemental abundances of carbon and oxygen in the warm molecular layers of some protoplanetary disks are depleted compared to those is the inters…
Discovery of Line Pressure Broadening and Direct Constraint on Gas Surface Density in a Protoplanetary Disk
Tomohiro C. Yoshida, Hideko Nomura, Takashi Tsukagoshi +2
The gas surface density profile of protoplanetary disks is one of the most fundamental physical properties to understand planet formation. However, it is challenging to determine t…
Detection of HC18O+ in a protoplanetary disk: exploring oxygen isotope fractionation of CO
Kenji Furuya, Takashi Tsukagoshi, Chunhua Qi +4
The oxygen isotope fractionation scenario, which has been developed to explain the oxygen isotope anomaly in the solar system materials, predicts that CO gas is depleted in 18O in…
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.…
Chemical complexity of phosphorous bearing species in various regions of the Interstellar medium
Milan Sil, Satyam Srivastav, Bratati Bhat +10
Phosphorus related species are not known to be as omnipresent in space as hydrogen, carbon, nitrogen, oxygen, and sulfur-bearing species. Astronomers spotted very few P-bearing mol…
Modeling chemistry during star formation: Water deuteration in dynamic star-forming regions
S. S. Jensen, J. K. Jørgensen, K. Furuya +2
Recent observations of the HDO/HO ratio toward protostars in isolated and clustered environments show an apparent dichotomy, where isolated sources show higher D/H ratios than…
