Ethynyl Around the HII Regions S255 and S257
نویسندگان
چکیده
We present the results of ethynyl (C2H) emission line observations towards S255 and S257 HII regions molecular cloud between them. Radial profiles brightness, column density, abundance C2H are obtained. show that radial profile is almost flat drops by a factor two cloud. At same time, we find at maximum point sources in cloud—the stars with lines or emitting X-ray. Line consistent assumption both have front back neutral walls those move relative to each other.

Anatomy of the S255–S257 complex - triggered high-mass star formation
We present a multi-wavelength (NIR to radio) and multi-scale (1 AU to 10 pc) study of the S255–S257 complex of young high-mass (proto)stars. The complex consists of two evolved HII regions and a molecular gas filament in which new generations of high mass stars form. Four distinct regions are identified within this dusty filament: a young NIR/optical source cluster, a massive protostar binary, ...
متن کاملOn the structure of giant HII regions and HII galaxies
We review the structural properties of giant extragalactic HII regions and HII galaxies based on two dimensional hydrodynamic calculations, and propose an evolutionary sequence that accounts for their observed detailed structure. The model assumes a massive and young stellar cluster surrounded by a large collection of clouds. These are thus exposed to the most important star-formation feedback ...
متن کاملAnomalous emission from HII regions
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at ∼ 10 − 60 GHz. One of the best examples of spinning dust comes from a HII region in the Perseus molecular cloud. Observations of other HII regions also show tentative evidence for excess emission at frequencies ∼ 30 GHz, although at lower emissivity levels. A new detection of excess emission at...
متن کاملNarrowband CCD Photometry of Giant HII Regions
We have obtained accurate CCD narrow band Hβ and Hα photometry of Giant HII Regions in M 33, NGC 6822 and M 101. Comparison with previous determinations of emission line fluxes show large discrepancies; their probable origins are discussed. Combining our new photometric data with global velocity dispersion (σ) derived from emission line widths we have reviewed the L(Hβ)) − σ relation. A reanaly...
متن کاملHydrodynamics of Cometary Compact Hii Regions
We present numerical radiation-hydrodynamic simulations of cometary H II regions for a number of champagne flow and bowshock models. For the champagne flow models we study smooth density distributions with both steep and shallow gradients. We also consider cases where the ionizing star has a strong stellar wind, and cases in which the star additionally has a proper motion within the ambient den...
