ALMA Spectral Survey of An eruptive Young star, V883 Ori (ASSAY): II. Freshly Sublimated Complex Organic Molecules (COMs) in the Keplerian Disk
Jae-Hong Jeong, Jeong-Eun Lee, Seonjae Lee +9
We present an investigation of Complex Organic Molecules (COMs) in the spatially resolved Keplerian disk around V883 Ori, an eruptive young star, based on a spectral survey carried…

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…
