Ultra-dense ionization of hydrogen around the CO region of high-speed gas
Abstract
The results of high-velocity 12CO (J=1-0) molecular radiation in 77 star-forming regions with interspecific water pulsating source and super dense ionization hydrogen region are given. The aim of this study is to investigate the effects of high-speed molecular outflow, interstellar H2O (F25μm / F12μm)> 0.57 and lg (F60μm / F12μm)> 1.3. The vast majority of the sources have high temperature of the gas. At the level of 1σ Ta*, almost 70% of the source's full width (FW) exceeds 15 km s-1, 15% of the source is more than 30 km s-1. This result greatly exceeds the low mass star. There is a clear correlation between the FW of the CO molecule, the full width at half maximum (FWHM) and the infrared light of the source, and the values of the two linewidths are proportional to the values of the infrared luminosity. The bright source can inject more energy into its surrounding matter to produce a stronger outflow that increases the linewidth of the CO molecule, and from the corresponding relationship between the peak velocity of the CO molecule and the water ripple, The gas near it exhibits a large blue shift, which may have been caused by the amplification of the background source by the unsaturated maser.
