Imaging of HH80-81 Jet in the Near-infrared Shock Tracers H2 and [Fe ii]
The Astrophysical Journal, 2023 The HH80-81 system is one of the most powerful jets driven by a massive protostar. We present new near-infrared (NIR) line imaging observations of the HH80-81 jet in the H _2 (2.122 μ m) and [Fe ii ] (1.644 μ m) lines.

The HH 24 Complex: Jets, Multiple Star Formation, and Orphaned Protostars
The Astronomical Journal, 2023 The HH 24 complex harbors five collimated jets emanating from a small protostellar multiple system. We have carried out a multiwavelength study of the jets, their driving sources, and the cloud core hosting the embedded stellar system, based on data from

A jet model of Herbig-Haro objects [PDF]
Symposium - International Astronomical Union, 1987 We present results of steady jet calculations in which the cooling and compression behind internal shocks leads to optical emission with an intensity pattern similar to the regular well-aligned emission knots characteristic of stellar jets.

ALMA Observations of the Extraordinary Carina Pillars: A Complementary Sample
The Astrophysical Journal, 2023 We present a study of six dusty and gaseous pillars (containing the Herbig–Haro (HH) objects HH 1004 and HH 1010) and globules (that contain the HH 666, HH 900, HH 1006, and HH 1066 objects) localized in the Carina Nebula using sensitive and high-angular-

Bow shock models of Herbig-Haro objects [PDF]
Symposium - International Astronomical Union, 1987 It has recently been found that models of a radiating bow shock can explain qualitatively the strange emission line profiles observed in some Herbig-Haro (H-H) objects. It is also possible to compare directly the emission line intensity maps predicted from these models with CCD images of H-H objects.

International Astronomical Union Colloquium, 1977 AbstractAfter a brief introductory discussion of the statistics of known Herbig-Haro (HH) objects we present a survey of recent spectroscopic results in the ultraviolet, the optical and the near infrared range (the latter mostly in connection with H2 observations).

The Discovery of Herbig–Haro Objects in LDN 673 [PDF]
The Astrophysical Journal, 2017 Abstract We report the discovery of 12 faint Herbig–Haro (HH) objects in LDN 673 found using a novel color-composite imaging method that reveals faint Hα emission in complex environments. Follow-up observations in [S ii] confirmed their classification as HH objects.

Theoretical models of Herbig-Haro objects [PDF]
Symposium - International Astronomical Union, 1987 A brief overview of the observational characteristics of HH objects is given. Current models for their production by the interaction of stellar winds and jets with interstellar gas are critically discussed. Models for two specific systems of HH objects, namely, the Orion HH objects and the HH46-47 system are described with reference to the general ...
