Thermodynamic properties of the ionized gas 3He
In this article, we have calculated some thermodynamic properties for a system consisting of singy ionized 3He atoms and their corresponding removed electrons by employing the second quantization method at finite temperature. To perform the calculations, we have considered the kinetic term, and Coulomb interaction between the particles in our Hamiltonian. The calculated properties are free ener...
متن کاملAstronomy and Astrophysics Diffuse Ionized Gas toward Β Canis Majoris ⋆
This paper presents the study of the interstellar medium toward β CMa, a disk sight-line known for its low neutral gas density. This study uses high and medium resolution HST-GHRS spectra including lines from the following species : H i, D i, N i, O i, S ii, S iii, Si ii, Si iii, Si iv, Al ii, Al iii, Fe ii, Mg i, Mg ii, Mn ii, C ii and C iv. The line of sight to β CMa (153 pc) is dominated by ...
متن کاملLong slit spectroscopy of diffuse ionized gas in NGC 55 ⋆
Spectroscopic measurements of emission line ratios and velocities are presented for ionized gas across the central plane of NGC 55, a late-type galaxy in the Sculptor group. The low metallicity in NGC 55 leads to relatively low line ratios of [S ii]/Hα and [N ii]/Hα for H ii regions as well as the diffuse ionized gas. These are the first spectroscopical measurements of line ratios in ionized ga...

متن کاملRadiative feedback from ionized gas
H2 formation in metal-free gas occurs via the intermediate H − or H+2 ions. Destruction of these ions by photodissociation therefore serves to suppress H2 formation. In this paper, I highlight the fact that several processes that occur in ionized primordial gas produce photons energetic enough to photodissociate H− or H+2 and outline how to compute the photodissociation rates produced by a part...
