Dust Filaments and Star Formation in OMC-2 and OMC-3
We have mapped the 1300 μm dust emission of a 6' × 16' field in the OMC-2 and -3 region and detected an extended filamentary structure with at least 11 embedded condensations in OMC-2 and 10 inExpand
HERBIG-HARO FLOWS: Probes of Early Stellar Evolution
▪ Abstract Outflow activity is associated with all stages of early stellar evolution, from deeply embedded protostellar objects to visible young stars. Herbig-Haro (HH) objects are the opticalExpand
Visual Binaries in the Orion Nebula Cluster
We have carried out a major survey for visual binaries toward the Orion Nebula Cluster, using images obtained with the Advanced Camera for Surveys on the Hubble Space Telescope through an Hα filter.Expand
Radio Continuum Maps of Deeply Embedded Protostars: Thermal Jets, Multiplicity, and Variability
We have carried out a deep, 3.6 cm radio continuum survey of young outflow sources using the Very Large Array in its A configuration providing subarcsecond resolution. The seven regions observed areExpand
VLA Detection of Protostars in OMC-2/3
The OMC-2/3 molecular clouds contain one of the highest concentrations of protostars known in nearby molecular clouds. We have observed an area of about 6' × 15' (0.8 pc × 2 pc) covering the OMC-2/3Expand
Mm/Submm images of Herbig-Haro energy sources and candidate protostars
We present 450, 850 m and 1300 m images of regions with embedded candidate protostars. Some of them are associated with HH objects (HH 7-11, HH 1-2, HH 147, HH 111, HH 108) and have been previouslyExpand
The Formation of Brown Dwarfs as Ejected Stellar Embryos
We conjecture that brown dwarfs are substellar objects because they have been ejected from small newborn multiple systems that have decayed in dynamical interactions. In this view, brown dwarfs areExpand
H emission in pre-main sequence stars. I. An atlas of line profiles
We present an atlas of very high resolution ( R ~ 50000) H α line profiles of 63 pre-main sequence stars, divided among 43 T Tauri stars, 18 Herbig Ae/Be stars, and 2 FU Orionis objects. H α emissionExpand
X-Rays from the Vicinity of the Protostar L1551 IRS 5: Reflection or Fast Shocks?
We present new Chandra X-Ray Observatory observations of the L1551 molecular cloud in Taurus. We find a compact, but slightly resolved, X-ray source, displaced westward from the IRS 5 binaryExpand
