Ice in the Pipe and beyond


  • Dr. Miwa GOTO

Primary authors


We observed the water ice toward the starless cores in the Pipe Nebula. The motivation is to look at the early phases of the ice accretion in the environment devoid of star formation. The water ice optical depth in the Pipe Nebula is about half as much as is expected by the canonical relation of the ice optical depth on A_V in Taurus. One of the explanations is the formation of the ice mantle is in progress, and the chemistry has not reached the steady state yet. We will present a plan how we could explore the building of the first layer of the ice on bare grains at the time of the JWST.
