Precision Analysis of ${}^{12}\mathrm{C}{/}^{13}\mathrm{C}$ Ratios in Orion IRc2 Acetylene Isotopologues via $\ddot{I}{‡}^2$ Fitting

Minkyu Lee, Jubin Park, Sehoon Oh +2

We present a detailed analysis of acetylene (C${}_2$H${}_2$) and its isotopologues in the Orion IRc2 region, focusing on the determination of ${}^{12}$C/${}^{13}$C isotopic ratios using hi…
