Chemistry of Protoplanetary Disks
In a later stage of low-mass star formation, a protoplanetary disk is formed around a newly born star, and it evolves into a planetary system. Chemical compositions of protoplanetary disks have been studied by radio and infrared observations. In this chapter, chemistry of protoplanetary disks is outlined after an overview of their physical conditions. Chemical compositions are discussed for four representative parts of a disk, disk midplane, disk surface, molecular zone, and inner disk. Molecules found in comets are briefly introduced in relation to disk chemistry.
