Neutral Hydrogen and the Diffuse Interstellar Medium,entric radius 8 kpc (Blitz et al. 1983). Unlike H., HI is not concentrated in a small number of giant clouds. Estimates of the “filling factor”, the fraction of the Galactic interstellar space occupied by hydrogen, range from 20% to 90%. These factors establish the preeminence of atomic hydrogen in the dynamics and evolution of the ISM.作者: 過(guò)去分詞 時(shí)間: 2025-3-23 18:38 作者: 離開(kāi)就切除 時(shí)間: 2025-3-23 23:36

Supernova Remnants,ynthesize heavy elements, and inject energy into the interstellar medium which can maintain turbulent cloud motions, heat a large fraction of the volume of the galaxy, and accelerate particles.
