JWST/NIRSpec Observations of Brown Dwarfs in the Orion Nebula Cluster

open access: yesThe Astrophysical Journal
We have used the multiobject mode of the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST) to obtain low-resolution 1–5 μ m spectra of 22 brown dwarf candidates in the Orion Nebula Cluster, which were selected with ...

PyEMILI: A New Generation Computer-aided Spectral-line Identifier. II. Emission-line Identification and Plasma Diagnostics of a Sample of Gaseous Nebulae

open access: yesThe Astrophysical Journal Supplement Series
In order to test the robustness and reliability of the new generation spectral-line identifier PyEMILI, as initially introduced in Paper I, in line identification and establish a reference/benchmark dataset for future spectroscopic studies, we run the ...

An observational survey of molecular emission ahead of Herbig-Haro objects

open access: yes, 2006
Context.A molecular survey recently performed ahead of HH 2 supports the idea that the observed molecular enhancement is due to UV radiation from the HH object.Aims.The aim of the present work is to determine whether all HH objects with enhanced HCO ...

Knot production in magnetized Herbig–Haro jets

open access: yes, 2002
We present the results of a simulation of an axisymmetric (2.5–dimensional), magnetized Herbig–Haro jet. The parameters are chosen for a typical collimated outflow from a young stellar low–mass object.

Emission line spectra of Herbig-Haro objects

open access: yesThe Astrophysical Journal Supplement Series, 1981
Spectrophotometric data have been obtained for 12 Herbig-Haro nebulae with the multichannel spectrometer on the Mt. Palomar 5.08 m telescope and with the image intensified dissector scanner on the Kitt Peak 2.13 m telescope. Optical emission line fluxes are presented for the following Herbig-Haro objects: H-H 1 (NW), H-H 1 (SE), H-H 2A, H-H 2G, H-H 2H,

IRAS sources associated with nebulosities resembling Herbig-Haro objects

open access: yes, 1988
The IRAS Survey has been used to search 22 nebulosities resembling Herbig-Haro objects for evidence of newly forming stars. Half the peculiar nebulae are found to have associated IRAS sources.

An extended catalogue of Herbig-Haro objects

open access: yes
We present an extended catalogue of 1193 Herbig-Haro (HH) objects, comprising 477 isolated HH objects and 716 HH knots, compiled through a meticulous review of the literature available through mid-2025. The catalogue provides comprehensive data for each entry, including celestial coordinates, distances, knot separations, exciting sources (with spectral
