An observational approach to interstellar gas dynamics

Bulletin astronomique, 1967
Les propriétés cinématiques des étoiles B0V -B2V diffèrent systématiquement de celles des étoiles B3V -B8V. En particulier les étoiles B0V -B2V ont des vitesses v systématiquement plus petites et des vitesses u systématiquement plus grandes que les étoiles B3V -B8V Cette conclusion vient d'une étude des vitesses radiales des étoiles situées entre 300 ...

Chemistry and Dynamics in the Interstellar Medium

2017
We present a brief introduction to interstellar chemistry, stressing its importance to modern astronomy as a diagnostic tool that can be used to interpret the present condition and evolutionary status of gas in the Milky Way and other galaxies. A short description of the main chemical pathways in the interstellar medium is given; these include gas ...

Dynamics and Energetics of the Interstellar Medium

1983
Some basic tools for the modeling of the dynamical properties of the diffuse interstellar medium are reviewed. First, an overview of fluid mechanics is given. Then, basic phenomena are presented: radiative losses, shocks, ionization fronts, and electron thermal conduction.

Dynamics and Equilibrium in the Interstellar Medium

2012
This chapter outlines some of the main dynamical processes occurring in the interstellar medium such as the expansion of H II regions, interstellar shock waves, stellar winds, and supernova remnants. The chapter ends with a discussion of the equilibrium of the different phases of the interstellar gas and star formation.

Exploiting orbital dynamics for interstellar separated spacecraft interferometry

Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999
Due to the much improved angular resolution achievable with an interferometer, a number of future NASA missions have resorted to using such an imaging system in an attempt to answer fundamental questions posed in the Origins Program. In this paper, the orbit designs of a Sun-synchronous separated spacecraft interferometer operating in the visible ...
