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 کاملIonized Gas in the Smith Cloud
We present Wisconsin Hα Mapper observations of ionized gas in the Smith Cloud, a high velocity cloud which Lockman et al. have recently suggested is interacting with the Galactic disk. Our Hα map shows the brightest Hα emission, 0.43± 0.04 R, coincident with the brightest H I, while slightly fainter Hα emission (0.25 ± 0.02 R) is observed in a region with H I intensities < 0.1 times as bright a...
متن کاملIonized Gas in Spheroids: The SAURON Survey
Early results are reported from the SAURON survey of the kinematics and stellar populations of nearby cluster and field E, S0, and Sa galaxies. We present maps of the Hβ and [OIII] emission-line distribution and kinematics for NGC 5813 and NGC 7742.

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...
