Hh Jets Aligned Perpendicular to Elephant Trunks
نویسنده
چکیده
We consider a system of outflows ejected from low mass young stars embedded in the tips of elephant trunks. We assume that these outflows have axes which are intrinsically perpendicular to the axes of the host elephant trunks. We then derive the distribution function expected for the angle between the projections of the outflow and elephant trunk axes on the plane of the sky. These distribution functions are useful for interpreting the alignments (or lack thereof) observed between HH outflow and elephant trunk axes in photoionized regions.

The angular momentum of condensations within elephant trunks
Aims. The radiation from newly born stars photoevaporates their parental neutral cloud, leading to the formation of dense clumps that will eventually form stars. Methods. We present 3D simulations of the interaction of a neutral cloud with an external ionising radiation field, and compute the angular momenta of these collapsing clumps. Results. The angular momenta of these collapsing clumps sho...
متن کاملInfall and Outflow around the Hh 212 Protostellar System
HH 212 is a highly collimated jet discovered in H2 powered by a young Class 0 source, IRAS 054130104, in the L1630 cloud of Orion. We have mapped around it in 1.33 mm continuum, CO (J = 2−1), CO (J = 2 − 1), CO (J = 2 − 1), and SO (JK = 65 − 54) emission at ∼ 2.5 ′′ resolution with the Submillimeter Array. A dust core is seen in the continuum around the source. A flattened envelope is seen in C...
متن کاملA dichotomy in the orientation of dust and radio jets in nearby low - power radio galaxies ⋆
We examine the properties of central dust in nearby quiescent and active early-type galaxies. The active galaxies are low-power radio galaxies with Fanaroff & Riley Type I or I/II radio jets. We focus on (a) the comparison of the dust distributions in the active and quiescent galaxy samples and (b) the relation between the radio jet and dust orientations. Our main observational conclusions are:...
متن کاملThe Theory of Photoionized Jets
From a theoretical point of view, these HH jets present a new challenge, in which the interplay between the jet dynamics and the external photoionization has to be understood. Also, these objects offer the possibility of making substantial progress in the understanding of HH jets: while in the “standard”, quasi-neutral HH jets we only observe limited regions of the jet beam (which are excited b...
متن کاملThe Orientation of Jets Relative to Dust Disks in Radio Galaxies
We use HST broad band images, VLA and VLBI continuum data to study the three dimensional orientation of jets relative to nuclear dust disks in 20 radio galaxies. The comparison between the position angles of the jets with those of the dust disks major axes shows a wide distribution, suggesting that they are not aligned preferentially perpendicular to each other. We use a statistical technique t...
