Oxygen in the Interstellar Medium
Reviews in Mineralogy and Geochemistry, 2008The oxygen that is observed in the Solar System today is a remnant of the interstellar oxygen that was in the dense molecular cloud that collapsed to form the Solar System. While the chemical evolution of the Galaxy has progressed since then, processes in the interstellar medium (ISM) that involve oxygen are relevant to the origins of oxygen in the ...

Although most of the mass of the Milky Way Galaxy is condensed into stars, interstellar space is not completely empty. It contains gas and dust, in the form both of individual clouds and of a diffuse medium. Interstellar space typically contains about one gas atom per cubic centimetre and 100 dust particles per cubic kilometre.

Except in particular situations, the behaviour of ordinary gases is adiabatic. In fact, due to the low values of the viscosity coefficients and thermal conductivity there is no thermal contact with the surrounding medium and the dissipation of energy by viscosity is negligible.

Small missions for energetic astrophysics, 1999
The study of the interstellar medium has been, and remains, a rich field for exploitation using small missions in the ultraviolet and X-ray spectral regions. I review the history of some such missions (of various sizes), and I also review the capabilities for study of the interstellar medium of “Hot Universe Background Explorer” (HUBE), as it was ...

Interstellar medium simulations
Astronomische Nachrichten, 2012AbstractIn this review we critically assess numerical simulations of the interstellar medium (ISM), and argue that 3D high resolution calculations are the most promising method to determine the structure of the interstellar gas and follow its evolution well into the nonlinear regime. Based on a Riemann solver adaptive mesh refinement code, we present a

Turbulence in the Interstellar Medium [PDF]
Astrophysics and Space Science, 2004 Interstellar turbulence is expected to dissipate quickly in the absence of continuous energy input. I examine the energy available for driving the turbulence from six likely mechanisms: magnetorotational instability, gravitational instability, protostellar outflows, H II region expansion, stellar winds, and supernovae.

Astrophysics of the Interstellar Medium
2021This book is based on a series of lectures for an Astrophysics of the Interstellar Medium (ISM) master’s degree in Astrophysics and Cosmology at Padova University. From the cold molecular phase in which stars and planetary systems form, to the very hot coronal gas that surrounds galaxies and galaxy clusters, the ISM is everywhere.

This chapter gives a brief introduction on the interstellar medium (ISM). It starts with an overview (Sect. 1.1) of the ISM properties including some worth-mentioning historical events that took place during its discovery and exploration. We then highlight the importance of the dust in ISM (Sect.

Chemistry in the Interstellar Medium
Annual Review of Physical Chemistry, 1995Over the past 25 years, astronomers have discovered a large number of gas-phase molecules in space, ranging in size up to more than 10 atoms. The molecules, which are mainly organic in nature and comprise both normal and abnormal species, are located between stars, in regions known as interstellar clouds, which contain both gaseous material and ...
