Planets form in dusty, gas-rich circumstellar disks around young stars, while at the same time, the planet formation process alters the physical and chemical structure of the disk itself. Embedded planets will locally heat the disk and sublimate volatile-rich ices, or in extreme cases, result in shocks that sputter heavy atoms such as silicon from dust grains. This should cause chemical asymmetries detectable in molecular gas observations. Using archival...
