We present near-infrared [Fe ii] images of four Class 0/I jets (HH 1/2, HH 34, HH 111, HH 46/47) observed with the Hubble Space Telescope (HST) Wide Field Camera 3. The unprecedented angular resolution allows us to measure proper motions, jet widths and trajectories, and extinction along the jets. In all cases, we detect the counterjet, which was barely visible or invisible at shorter wavelengths. We measure tangential velocities of a few hundred kilometers per second, consistent with previous…

The time-dependent ejection velocity histories of HH 34 and HH 111
The southern lobe of HH 34 and the western lobe of HH 111 show remarkable similarities. Both objects have a chain of well aligned knots, ending in well defined bow shocks (HH 34S and HH 11 IV,
We present Spitzer (IRAC) images and a VLT 2.1 μm image of the HH 212 outflow. We find that this outflow has a strong symmetry, with jet/counterjet knot pairs with ∆x < 1 00 position offsets. We
Spiral structures in an embedded protostellar disk driven by envelope accretion
Hydrodynamical simulations show that a pair of spiral arms can form in the disk around a rapidly growing young star and that the arms are crucial in transporting angular momentum as the disk accretes
Giant Herbig-Haro Flows
Recent observations with wide field-of-view CCDs have shown that over 20 Herbig-Haro flows extend for more than one parsec from their driving sources. We review the observed properties of these giant
The relationship between infrared, optical, and ultraviolet extinction
The parameterized extinction data of Fitzpatrick and Massa (1986, 1988) for the ultraviolet and various sources for the optical and near-infrared are used to derive a meaningful average extinction
1–2.5 $\mu$m spectra of jets from young stars: Strong $\ion{Fe}{ii}$ emission in HH111, HH240-241 and HH120
As part of a 1-2.5m spectroscopic survey of jets and molecular outflows, we present the spectra of three Herbig Haro chains (HH111, HH240/241, HH120) characterized by strong emission from several
Molecular hydrogen in the outflow from Cep E
We present images of the outflow from Cep E in the 1-0 S(1), the 2-1 S(1), and, for the first time in any outflow, the 3-2 S(3) line of molecular hydrogen. These are supplemented by [Fe II]1.64 I¼m
New, high‐resolution, near‐infrared observations of HH 1
We present new, high-resolution, near-infrared images of the HH 1 jet and bow shock. H2 and [Fe ii] images are combined to trace excitation changes along the jet and across the many shock features in
