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.

Evolution of Southern Star-Forming Regions

1998
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 ...

Carbon Dioxide in Star-forming Regions

The Astrophysical Journal, 2000
We consider the gas-phase chemistry of CO2 molecules in active regions. We show that CO2 molecules evaporated from dust in hot cores cannot be efficiently destroyed and are in fact copiously produced in cooler gas. When CO2-rich ices are sputtered in strong MHD shock waves, the increase in atomic hydrogen, due to H2 dissociation by ion-neutral ...

Masers in Star-Forming Regions [PDF]

, 1999
The subject of astronomical masers is now more than forty years old, and as a consequence, several good reviews have appeared in print. For the readers who want to enter the subject of astronomical masers in a serious way, we want to recommend two reviews (Elitzur 1982; Reid and Moran 1988) and a book (Elitzur 1992a).

Star-Forming Regions

2012
Satisfactory assessments of star forming regions in the Galaxy are essential for the understanding of early stellar evolution and today a vast amout of astronomical studies are available. Star-forming regions distinguish themselves from other regions in the Galaxy. Many different physical processes are displayed with high levels of variability, a large
