The Interstellar Medium and Protostars

2014
When we look up into the night sky we see stars, and not much else. So we get the impression that between the stars, space is empty. There doesn’t seem to be any sort of material that lies between one star and another. At the same time, we know intuitively that this cannot be true, for if space were empty, from what did stars form?

Modeling the Local Interstellar Medium

Astrophysics and Space Science, 2001
The state of our observational and theoretical knowledge of the local interstellar medium (LISM) is reviewed. The LISM stretches out from the local Cloud, surrounding the solar system to the boundary of the Local Bubble, which is a region of distinct anticorrelation between HI (NH <1020 cm-2) and 1/4 keV diffuse soft X-rays.

Ammonia in the interstellar medium

AIP Conference Proceedings, 1994
I discuss the astrophysical importance of ammonia in the interstellar medium with special reference to its’ use as a ‘‘thermometer’’. A very brief overview is given of the observations of interstellar ammonia in cold dark clouds and in hot star forming regions.

Local Interstellar Medium

1998
This report summarizes the issues discussed in Working Group VI concerning the accuracy of measurements of D/H and 3He/H in the local interstellar medium, possible systematic errors, and emerging trends in the results.

Sulfur Hydrides in the Interstellar Medium

2014
Whereas H2S was one of the first triatomic molecules detected in interstellar ▶molecular clouds (in 1972), the identification of SH (in 2011) and SH (in 2012) has been much more recent. Although H2S and SH + were observed using ground-based radio telescopes, radio astronomers used the SOFIA airborne observatory to detect SH (see▶Molecules in Space and ...
