Figure 1. Stratified distribution of organic molecules at the planet-formation scale in the HH 212 disk atmosphere. Organic molecules including H2CO, CH3OH, NH2CHO, and HCOOH are sublimated into the gas phase from the ice mantle (cyan) on dust grains (gray) in the disk into the disk atmosphere. A molecule with a lower sublimation temperature starts to appear at a larger radius where the temperature is lower. Credit: Lee et al.
The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of the European Organization for Astronomical Research in the Southern Hemisphere (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile. ALMA is funded by ESO on behalf of its Member States, by NSF in cooperation with the National Research Council of Canada (NRC) and the Ministry of Science and Technology (MOST) and by NINS in cooperation with the Academia Sinica (AS) in Taiwan and the Korea Astronomy and Space Science Institute (KASI).
ALMA construction and operations are led by ESO on behalf of its Member States; by the National Radio Astronomy Observatory (NRAO), managed by Associated Universities, Inc. (AUI), on behalf of North America; and by the National Astronomical Observatory of Japan (NAOJ) on behalf of East Asia. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
This research was presented in a paper “Stratified Distribution of Organic Molecules at the Planet-formation Scale in the HH 212 Disk Atmosphere” by Lee et al. appeared in Astrophysical Journal.
