6 A photoionized Herbig - Haro object in the Orion nebula
The spectra of Herbig Haro objects are usually characteristic of ionization and excitation in shock-heated gas, whether an internal shock in an unsteady outflow or a bow shock interface with the interstellar medium. We examine the eastern-most shock – the leading optically visible shock – of a Herbig Haro outflow (HH 529) seen projected on the face of the Orion Nebula, using deep optical echell...
متن کاملWide Field Surveys of Herbig-Haro Objects
We report our new results from wide-field surveys of Herbig-Haro (HH) objects in the nearby star forming regions. The surveys covered approximately 56 deg in Perseus, Taurus, Orion, Monoceros, and other regions. Using refined techniques, we discovered in total 68 HH objects, of which 32 were in Perseus, 4 in Taurus, 13 in Orion, 18 in Monoceros, and 1 in S287 regions. The newly discovered HH ob...
متن کاملHerbig - Haro Jets in the Orion Nebula and near Ngc 1333
We report the discovery of a dozen Herbig-Haro jets illuminated by the Lyman continuum (λ < 912Å) and/or softer far-ultraviolet (912Å < λ < 2000Å) radiation fields of nearby high mass stars. Five irradiated outflows lie in the outer parts of the Orion Nebula (HH 502 through HH 506) and seven lie near the reflection nebula NGC 1333 in the Perseus molecular cloud (HH 333 through HH 336, and HH 49...
متن کاملNew Herbig–Haro Objects and Giant Outflows in Orion
We present the results of a photographic and CCD imaging survey for Herbig–Haro (HH) objects in the L1630 and L1641 giant molecular clouds in Orion. The new HH flows were initially identified from a deep Hα film from the recently commissioned AAO/UKST Hα Survey of the southern sky. Our scanned Hα and broad band R images highlight both the improved resolution of the Hα survey and the excellent c...
متن کاملStar Formation in IC 348
A review of work on the small, compact, nearby young cluster IC 348 is given. This region is particularly important because it is well surveyed at a variety of wavelengths and intermediate in nature between dense clusters and loose associations. Its earliest type star is B5 and it contains a few hundred stellar members as well as some brown dwarfs, protostars, Herbig-Haro objects and starless s...
