Correlating Infall with Deuterium Fractionation in Dense Cores
Scott Schnee, Nathan Brunetti, James Di Francesco +4
We present a survey of HCO+ (3-2) observations pointed towards dense cores with previous measurements of N(N2D+)/N(N2H+). Of the 26 cores in this survey, five show the spectroscopi…
Abundant cyanopolyynes as a probe of infall in the Serpens South cluster-forming region
R. K. Friesen, L. Medeiros, S. Schnee +4
We have detected bright HC7N J = 21-20 emission toward multiple locations in the Serpens South cluster-forming region using the K-Band Focal Plane Array at the Robert C. Byrd Green…
Resolved Depletion Zones and Spatial Differentiation of N2H+ and N2D+
John J. Tobin, Edwin A. Bergin, Lee Hartmann +6
We present a study on the spatial distribution of N2D+ and N2H+ in thirteen protostellar systems. Eight of thirteen objects observed with the IRAM 30m telescope show relative offse…
