Chemistry in Protoplanetary Disks
arxiv(2024)
摘要
Planets are formed inside disks around young stars. The gas, dust, and ice in
these natal disks are the building materials of planets, and therefore their
compositions fundamentally shape the final chemical compositions of planets. In
this review, we summarize current observations of molecular lines in
protoplanetary disks, from near-infrared to millimeter wavelengths. We discuss
the basic types of chemical reactions in disks and the current development of
chemical modeling. In particular, we highlight the progress made in
understanding snowline locations, abundances of main carriers of carbon,
oxygen, and nitrogen, and complex organic molecules in disks. Finally, we
discuss efforts to trace planet formation history by combining the
understanding of disk chemistry and planet formation processes.
