Warm HCN, C2H2, and CO in the disk of GV Tau.

Abstract (from CDS):

We present the first high-resolution, ground-based observations of HCN and C2H2 toward the T Tauri binary star system GV Tau. We detected strong absorption due to HCN ν3 and weak C2H23and ν2+(ν45)0+] absorption toward the primary (GV Tau S) but not the infrared companion. We also report CO column densities and rotational temperatures, and present abundances relative to CO of HCN/CO∼0.6% and C2H/CO∼1.2% and an upper limit for CH4/CO<0.37% toward GV Tau S. Neither HCN nor C2H2 were detected toward the infrared companion, and results suggest that abundances may differ between the two sources.
