Abstract A study of the structure of the dense core in the dark cloud Barnard 5 (B5) and the circumstellar environment of B5 IRS 1 is presented. CO-18 and CS observations show a dense core of about 50 solar masses with a velocity gradient around the NH3 core in B5. A map of the CO outflow from IRS 1 shows the outflow to extend in a direction nearly perpendicular to this velocity gradient. Observations of HCN with the Hat Creek Millimeter interferometer reveal three dense clumps each with mass of about 0.1 solar mass near the young star B5 IRS 1. Two of these clumps form an elongated structure which is both perpendicular to the CO outlfow from IRS 1 and parallel to the direction of the velocity gradient seen in the core material.
