Chemistry and Star Formation
Edwin A. Bergin University of Michigan, Ann Arbor, USA | |
| Chemistry plays a major role in the early stages of stellar birth. I will review how the chemical composition begins with the initial atomic state and develops increasing molecular complexity as the cloud forms and the dense core condenses. A key aspect of the latter stages is the interaction of molecules with grain surfaces. I will review the chemistry and physics of this interaction and the various methods that star formation dynamics and chemistry have been coupled. I will show how understanding the chemical evolution can provide evolutionary signposts to selectively isolate and study specific stages. Furthermore detailed chemical models can provide important constraints on the uncertain timescales of star formation. As possible reference will be given to Herschel results on key species such as water. | |
