AbstractWe present a BIMA molecular line study of the class 0 source Barnard 1-c in the Perseus molecular cloud. As followup to the detection of an atypical polarization pattern in this young stellar object by Matthews & Wilson (2002), we have obtained high resolution data in CO, C¹⁸O, ¹³CO, HCO⁺, and N₂H⁺ from BIMA, plus N₂H⁺ data from FCRAO. N₂H⁺ is destroyed in the core centre and along the jet axis due to the high abundance of CO. The N₂H⁺ data demonstrate that this core is rotating (see Figure 1) with its rotation axis aligned with the observed molecular outflow. We have used high spectral resolution data of N₂H⁺ to measure the velocity and linewidths across the core. In addition, we present models of the SED (using BIMA, JCMT, IRAS and Spitzer data) generated with DUSTY in order to estimate the size scale of the evaporated region. We compare the morphology and kinematics of the B1-c core and jet to those of NGC 1333 IRAS 2 and IRAM 04191+1522, another very young class 0 source.>
