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…
A new method for direct measurement of isotopologue ratios in protoplanetary disks: a case study of the CO/CO ratio in the TW Hya disk
Tomohiro C. Yoshida, Hideko Nomura, Kenji Furuya +2
Planetary systems are thought to be born in protoplanetary disks. Isotope ratios are a powerful tool for investigating the material origin and evolution from molecular clouds to pl…
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…
