ATCA and Spitzer Observations of the Binary Protostellar Systems CG 30 and BHR 71
We present interferometric observations with resolution of ∼ 3′′ of the isolated, low-mass protostellar double cores CG 30 and BHR 71 in the N2H + (1− 0) line and at 3 mm dust continuum, using the Australian Telescope Compact Array (ATCA). The results are complemented by infrared data from the Spitzer Space Telescope. In CG 30, the 3 mm dust continuum images resolve two compact sources with a s...
متن کاملIn Bhr 71 : a Binary Protostellar System ?
New Anglo-Australian Telescope near-infrared and Swedish-ESO Submillimetre Telescope CO obJ p 2 r 1 servations are combined with existing Infrared Space Observatory mid-infrared and Australia Telescope Compact Array centimeter radio continuum observations to examine the protostellar content of the Bok globule BHR 71. Together with observations of Herbig-Haro objects, these data show the followi...
متن کاملMolecular Line Observations of the Small Protostellar Group L1251B
We present molecular line observations of L1251B, a small group of preand protostellar objects, and its immediate environment in the dense CO core L1251E. These data are complementary to near-infrared, submillimeter and millimeter continuum observations reported by Lee et al. (2006, ApJ, 648, 491; Paper I). The single-dish data of L1251B described here show very complex kinematics including inf...
متن کاملSio Observations of the Ngc 1333 Iras 2a Protostellar Jet
We present 86.8 GHz SiO J=2-1 observations of the molecular outflow from the protostellar source NGC 1333 IRAS 2A. Silicon monoxide is a sensitive tracer of shocks in molecular gas, and the emission clearly traces terminal bow-shocks at the ends of the outflow lobes, as well as emission knots and a source coincident with the protostar. Our three-field mosaic from the BIMA interferometer covers ...
متن کاملHh 212: Sma Observations of a Remarkable Protostellar Jet
HH 212 is a nearby (460 pc) protostellar jet discovered in H2 powered by a Class 0 source, IRAS 05413-0104, in the L1630 cloud of Orion. It is highly collimated and symmetric with matched pairs of bow shocks on either side of the source. We have mapped it in 850 μm continuum, SiO (J = 8− 7), CO (J = 3−2), SO (NJ = 89−78), HCO + (J = 4−3), and HCO (J = 4−3) emission simultaneously at ∼ 1 resolut...
