Abstract

Near-IR observations of CO isotopologues taken at high spectral resolution toward young stellar objects (YSOs) enable valuable comparisons between YSOs and solar system material, as well as robust evaluation of early protoplanetry chemical reservoirs. Recent observations toward low-mass, solar-type YSOs revealed signatures consistent with CO self-shielding, as well as significant heterogeneity in [^(12)C^(16)O]/[^(13)C^(16)O]Gas, which may in part be due to interplay between CO ice and gas. Toward expanding this investigation of early protostellar phenomena to include a range of environments, we present new observations toward massive, luminous YSOs with varying CO ice abundances along a single line-of-sight. These data are part of our ongoing study of carbon reservoirs beyond our solar neighborhood (R_(GC) ~ 8 kpc).
