Title:CONSTRAINING SULFUR ISOTOPE ABUNDANCES IN MOLECULAR CLOUDS: A METEORITIC PERSPECTIVE
Author(s):Bernal, Jacob

Subject(s):Astronomy
Abstract:Carbonaceous chondrite class meteorites exhibit isotopic enrichments in deuterium, $^{13}$C, $^{15}$N, and possibly $^{33}$S, implying interstellar origins. To study possible sulfur enrichments, we have been conducting observations of SO in molecular clouds to determine abundance ratios between $^{32}$S, $^{34}$S, and $^{33}$S. The N=2-1 3mm transitions of SO have been measured towards W51M, DR21, G34.3, W3(OH), and NGC7538 using the ARO 12m telescope. The sulfur isotope ratios are currently being calculated and will be compared to meteoritic samples (Bose et al. 2017). The results presented will help to determine the connection between molecular cloud and meteoritic materials.
