Dark cloud chemistry in initially H-rich regions
The chemistry in dark regions of dense cores is explored as a function of the initial abundance ratio of H to H2, on the assumption that some cores form on a timescale and are younger than the time required for the H:H2 ratio to attain its equilibrium value. Observational diagnostics of non-equilibrium values of the initial H:H2 ratio are identified. In initially H-rich material, the abundances...
متن کاملConsequences of Dust in Metal-Rich H II Regions
Dust and associated depletion of heavy elements from the gas phase can modify the thermal properties of H II regions from the dust-free case, with significant consequences for the emergent optical spectrum. We present the results of theoretical calculations illustrating the effects of grains on the spectra of giant, extragalactic H II regions, with emphasis on high metallicity systems (Z > ∼ Z⊙...
متن کاملAbundances of Metal-rich H Ii Regions in M51 1
We have obtained multi-object spectroscopy of H II regions in the spiral galaxy M51 with the Keck I telescope and the Low Resolution Imaging Spectrometer. For ten objects we have detected the auroral line [N II]λ5755, while [S III]λ6312 has been measured in seven of these. This has allowed us to measure the electron temperature of the gas and to derive oxygen, sulfur and nitrogen abundances for...
متن کاملMeasuring Chemical Abundances in Extragalactic Metal-Rich H II Regions
The analysis of metal-rich H ii regions has a profound impact on the calibration of abundance diagnostics widely used to measure the chemical content of star-forming galaxies, both locally and at high redshift. I review the main difficulties that affect direct abundance determinations from temperature-sensitive collisionally excited lines, and briefly discuss strong-line methods, in particular ...
متن کاملCloud Chemistry
Tbe term cloud chemistry is considered bere to comprise both cloud composition and reactions that take place in clouds. Clouds are a very special subset of tbe atmosphere because they present substantial amounts of condensed-phase water (liquid or solid) that can dissolve gases that would otherwise be present in the gas phase, and, as a consequence of condensed-phase reactions, pennit reactions...
