Abstract

We present a study of outflows driven by $\sim$30 protostars using CARMA 1.3 mm observations ($\sim$2.5$^{\prime\prime}$ resolution) of CO ({\it J} = 2 $\rightarrow$ 1) and SiO ({\it J} = 5 $\rightarrow$ 4). The sample is taken from the CARMA protostellar polarization survey. The polarization measurements revealed that the magnetic fields are either randomly oriented or preferentially oriented perpendicular to the molecular outflow axis. To probe the properties of the outflow itself, we calculate the mass, momentum, and kinetic energy of each outflow. To examine outflow evolution, we measure the opening angles of each outflow and examine how these vary with age determined from the bolometric temperature. When the protostellar targets are multiple systems, we attempt to disentangle the outflows originating from each component in order to study the system in detail. Observations of molecules such as CO and SiO are key to detecting outflows and determining their properties, which in turn helps constrain the details of the underlying physics driving outflows and how the outflows relate to their driving protostars.
