Chemistry in protoplanetary disks

K Zhang - Reviews in Mineralogy and Geochemistry, 2024 - pubs.geoscienceworld.org
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 …
