Abstract

Our ALMA Cycle 0 and 2 observations in Band 6 provide tracers of the disk (C¹⁸O, ¹³CO), the envelope (¹³CO, DCO⁺) and the outflow and its cavity (¹²CO, ¹³CO, c-C₃H₂) towards VLA1623, a triple non-coeval system in ρ Ophiuchus (d∼120 pc). The observations are combined with simple chemical and physical models. We find differing circumstellar envelope and outflows. VLA1623 appears to not be as chemically rich as other deeply embedded sources.
