概要 | Abstract
We report on an Atacama Large Millimeter/submillimeter Array study of the Class I or II intermediate-mass protostar DK Cha in the Chamaeleon II region. The 12CO(J = 2-1) images have an angular resolution of ~1 (~250 au) and show high-velocity blueshifted (>=70 km s-1) and redshifted (>=50 km s-1) emissions, which have 3000 au scale crescent-shaped structures around the protostellar disk traced in the 1.3 mm continuum. Because the high-velocity components of the CO emission are associated with the protostar, we concluded that the emission traces the pole-on outflow. |
