High-Energy Particles and Radiation in Star-Forming Regions

Space Science Reviews, 2020
Non-thermal particles and high-energy radiation can play a role in the dynamical processes in star-forming regions and provide an important piece of the multiwavelength observational picture of their structure and components.

Evolution of Southern Star-Forming Regions

Astrophysics and Space Science, 1997
We present ISO observations of bright, high-mass southern star-forming regions with the Short Wavelength Spectrometer (SWS) and Long Wavelength Spectrometer (LWS). The selected targets show a range of pre-main sequence evolutionary phases. Whereas some objects still show interstellar ice features, the most evolved objects are coincident with ...

Star forming regions

Vistas in Astronomy, 1988
With recent improvements in the mm-wave, IR and high-sensitivity optical observations various new features of star formation embedded in dark clouds have been revealed. These are expanding shock fronts due to newly formed massive stars, gaseous disks surrounding proto stars, the energetic bipolar molecular flows, and the weRlcollimat'ed ionized jets ...

Chemistry of Star-Forming Regions

The Journal of Physical Chemistry A, 2005
The space between stars is not empty but contains gas-phase and particulate matter under varying conditions. Neutral matter is found mainly in large regions of the interstellar medium known as "clouds", the largest of which, termed "giant molecular clouds", are essentially molecular in nature.

Clumpiness in Star Forming Regions

Astrophysics and Space Science, 2003
In this article, some aspects of the clumpy nature of molecular clouds are reviewed. In particular the observational evidence for small-scale structures both in low and high mass star forming regions will be discussed. I will review some examples of `clumpiness' such as: i) the molecular clumps ahead of HH objects and how the study of the physical and ...
