Origins of complex organic molecules in L1551 IRS 5: Interplay of thermal heating and accretion shocks
Ji-hyun Kang, Jeong-Eun Lee, Seokho Lee +1
Complex organic molecules (COMs) are typically observed in the warm inner envelopes of Class 0 protostars. In more evolved Class I sources, COM emission is confined to the compact…

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…
