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 Objects around Cg 30
In this work we study Herbig-Haro objects located in the region around the head of the cometary globule CG 30. Two sets of optical images are presented. The first set was obtained with the 3.5 m New Technology Telescope in 1995 in three emission lines: Hα, [S II]λλ6731,6716Å and [O II]λ3729Å. The second set is an Hα image of the CG 30/31/38 complex obtained in 2006 with the 8 m Subaru telescope...
متن کاملHerbig - Haro flows in L 1641 N ⋆ , ⋆ ⋆
Aims. To study the Herbig-Haro (HH) flows in L1641N, an active star formation region in the southern part of the Orion GMC and one of the most densely populated regions of HH objects in the entire sky. By mapping the velocities of these HH objects, combined with mid-IR observations of the young stars, the major flows in the region and the corresponding outflow sources can be revealed. Methods. ...
متن کاملIonization and density along the beams of Herbig-Haro jets
Physical properties of several well-known HerbigHaro jets are investigated using an improved version of the spectroscopic diagnostic technique originally developed by Bacciotti et al. (1995). The procedure allows one to derive in a model-independent way the hydrogen ionization fraction in regions of low excitation. The ionization fraction, the electron and gas density, and the average excitatio...
