    Context. Models of pure gas-phase chemistry in well-shielded regions of molecular clouds predict relatively high levels of molecular oxygen, O<SUB>2</SUB>, and water, H<SUB>2</SUB>O. These high abundances imply high cooling ...
  • Tracing pebble drift and trapping using radial carbon depletion profiles in protoplanetary disks
