The ortho and para fractions of molecular hydrogen in protostellar outflows and Herbig-Haro objects
Hydrogen molecules exist in two forms, according to the alignment of the nuclear spins. We present an accurate method for extracting the distributions of the two forms from three K-band infrared transitions. Images of the 1-0 S(0), S(1) and S(2) emission lines yield the ortho and para spatial distributions with negligible extinction and model dependence. The ortho-para ratio from individual poi...
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 کاملT Tauri Stars Associated with Herbig-haro Objects and Jets
We have obtained deep [S II] jj6716, 6731 and continuum images of the Ðve classical T Tauri stars (CTTSs) DP Tau, RW Aur, V536 Aql, LkHa 321, and V1331 Cyg. These CTTSs were selected for our imaging study because they either showed strong P Cygni absorptions in their spectra (LkHa 321, V1331 Cyg) or were known from long-slit spectroscopic studies to have bipolar jetlike outÑows (DP Tau, RW Aur,...
