Description
The study of protoplanetary disks provides invaluable insights into the processes governing planetary formation and the chemistry of the early solar systems. This talk will present new data on the detection of COMs in the disk around V883 Ori. Using high-resolution spectroscopy of Atacama Large Millimeter/submillimeter Array (ALMA) Band 7 observations, we explored the spatial distribution and chemical environment of several molecules. We detected 15 COMs and 10 other molecules (including isotopologues), with first detection of 6 molecules in this source, including some prebiotic molecules, which are considered the building blocks of life. We compared the abundances relative to methanol (CH3OH) with those in Class 0 protostars (IRAS 16293-2422 A, IRAS 16293-2422 B, B1-c), the Solar System comet 67P/Churyumov-Gerasimenko, Sgr B2 (N), and the protoplanetary disk of Oph-IRS 48. We report higher abundances compared to Class 0 protostars and similar abundances compared to the Sgr B2 (N) and 67P/C-G for the most of the molecules, and lower abundances compared to the protoplanetary disk Oph-IRS 48. Our findings underscore the significance of investigating the chemical complexity of protoplanetary disks and contribute to a broader understanding of the chemical evolution of protoplanetary disks.
