Star Formation and Related Topicssome of the problems involved and some results, mostly theoretical, of studies of star formation, concentrating on qualitative or “back-of-the-envelope” aspects. The first lecture will consider the collapse of individual protostars, as understood mainly from spherical collapse models; the second wil

Infrared Emission of the Galactic Center and Extragalactic Sources. In some cases, such as Seyfert galaxies, such processes are clearly occuring, but we are frustrated by the lack of detail that we can see in what is spatially an unresolved point. The Galactic Center would probably not hold our attention for long if we observed it from beyond the Local Group, but

Cosmological Aspects of Infrared and Millimetre Astronomytation that the infrared and submillimetre wavebands will be no exception to this rule. The aim of this short set of lectures is to discuss some of the more obvious aspects of particular interest to cosmology. Naturally, such predictions of what one expects to find in an unexplored waveband are haza

Infrared Astronomy from Space: A Review of Future Possibilitieso space is now set to occur in the early 1980’s. These will not strictly be the first infrared astronomical observations to be conducted from outside the earth’s atmosphere as there has been some military interest in this area for a number of years. A 2.7 μm equatorial sky survey is currently in pro

Far Infrared Emission of Molecular Clouds and Star Formation in the Galaxy The flux received in a 0.5. beam is larger than that received in a 0.25. beam, showing that the source (say at ∿5 kpc away) is ∿50 pc in size, typical for a molecular cloud, and too large for an HII region. An estimate of the dust temperature is obtained from 2 color photometry (75–95 μm band and 1

Shock Induced Star Formationcircumstances which can be classified broadly into two categories. Some gravitational instabilities seem to proceed “spontaneously” in a dense cloud, as a natural part of the cloud’s evolution: For example, a cloud may form in a state of high internal energy, either thermal, magnetic or turbulent in
