The origin of the protostellar jet GGD 34 ?
GGD 34 is a protostellar jet with wiggles which are accompanied by “sine-like” variations in the radial velocity of the emitting material by as much as 60 km s−1. Thus GGD 34 is an interesting object to understand the physical mechanisms involved in the generation of wiggles in protostellar jets. In this work we present high resolution images obtained with the Canada-France-Hawaii Telescope (CF...
متن کاملProtostellar Outflow Evolution in Turbulent Environments
The link between turbulence in star formatting environments and protostellar jets remains controversial. To explore issues of turbulence and fossil cavities driven by young stellar outflows we present a series of numerical simulations tracking the evolution of transient protostellar jets driven into a turbulent medium. Our simulations show both the effect of turbulence on outflow structures and...
متن کاملCluster Formation in Protostellar Outflow-Driven Turbulence
Most, perhaps all, stars go through a phase of vigorous outflow during formation. We examine, through 3D MHD simulation, the effects of protostellar outflows on cluster formation. We find that the initial turbulence in the clusterforming region is quickly replaced by motions generated by outflows. The protostellar outflow-driven turbulence (“protostellar turbulence” for short) can keep the regi...
متن کاملGgd 27: X-rays from a Massive Protostar with an Outflow
We report the discovery of a cluster of Class I protostars in GGD 27. One of these protostars is the previously known, centrally located, GGD 27-ILL, which powers a massive bipolar outflow. We show that GGD 27-ILL, which is known to be the bright infrared (IR) source, IRAS 18162–2048, and a compact radio continuum source, is also the newly discovered hard X-ray source, GGD 27-X. The observation...
متن کاملA highly-collimated SiO jet in the HH212 protostellar outflow
We mapped the inner 40 ′′ of the HH212 Class 0 outflow in SiO(2–1), SiO(5–4) and continuum using the Plateau de Bure interferometer in its extended configurations. The unprecedented angular resolution (down to 0. 34) allows accurate comparison with a new, deep H2 image obtained at the VLT. The SiO emission is confined to a highly-collimated bipolar jet (width ∼ 0. 35) along the outflow axis. Th...
