Water in star‐forming regions with Herschel

Astronomische Nachrichten, 2011
AbstractThe Herschel Space Observatory is well suited to address several important questions in star‐ and planet formation, as is evident from its first year of operation. This paper focuses on observations of water, a key molecule in the physics and chemistry of star‐formation.

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 ...

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.

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 ...

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 ...

The star-forming region in Orion KL

Astronomy Letters, 2003
We have studied the fine structure of the active H2O supermaser emission region in Orion KL with an angular resolution of 0.1 mas. We found central features suggestive of a bipolar outflow, bullets, and an envelope which correspond to the earliest stage of low-mass star formation.
