Chemistry in Protoplanetary Disks

Publisher: arXiv 2013
Number of pages: 84
This comprehensive review summarizes our current understanding of the evolution of gas, solids and molecular ices in protoplanetary disks. Key findings related to disk physics and chemistry, both observationally and theoretically, are highlighted. We discuss which molecular probes are used to derive gas temperature, density, ionization state, kinematics, deuterium fractionation, and study organic matter in protoplanetary disks.

The main purpose of this volume is to reproduce and make available for study, the larger and more interesting nebulae and clusters, sixty-eight in number. James Edward Keeler was the director of the Lick observatory 1898 - 1900.

We review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the observations.

Flattened disks of cool dust and gas are found around almost all low mass stars shortly after their birth. This review addresses observations of the outer parts of protoplanetary disks with a focus on recent infrared and (sub-)millimeter results.

The formalism of the simple model of galactic chemical evolution (GCE) and its main ingredients are presented. It is stressed that GCE is not an astrophysical theory, but it provides a framework in which the large body of data may be interpreted.
