Chemical Diversity in High-mass Star Formation
Massive star formation exhibits an extremely rich chemistry. However, not much evolutionary details are known yet, especially at high spatial resolution. Therefore, we synthesize previously published Submillimeter Array high-spatial-resolution spectral line observations toward four regions of highmass star formation that are in various evolutionary stages with a range of luminosities. Estimatin...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Star formation and mass assembly in high redshift galaxies
Aims. The goal of this work is to infer the star formation properties and the mass assembly process of high redshift (0.3 ≤ z < 2.5) galaxies from their IR emission using the 24 μm band of MIPS-Spitzer. Methods. We used an updated version of the GOODS-MUSIC catalog, which has multiwavelength coverage from 0.3 to 24 μm and either spectroscopic or accurate photometric redshifts. We describe how t...
متن کاملChemical differentiation in regions of high-mass star formation
Our goals are to compare the CS, N2H and dust distributions in a representative sample of high-mass star forming dense cores and to determine the physical and chemical properties of these cores. We compare the results of CS(5–4) and 1.2 mm continuum mapping of twelve dense cores from the southern hemisphere presented in this work, in combination with our previous N2H(1–0) and CS(2–1) data. We u...
متن کاملHot Molecular Cores and High-mass Star Formation
This review covers hot cores in the context of high-mass star formation. After giving an overview of chemical processes and diversity during high-mass star formation, it reviews the 'warm envelope' phase which probably precedes the formation of hot cores. Some recent deter-minations of the cosmic-ray ionization rate are discussed, as well as recent evidence for hot cores around low-mass stars. ...
