[P-CG24] New Developments of Planetary Sciences with ALMA

Wed. May 29, 2019 10:45 AM - 12:15 PM 105 (1F)

The Atacama Large Millimeter/Submillimeter Array (ALMA) starated its science operation in 2011, and long-baseline observations have become available since 2014. With its high sensitivity and resolution, ALMA has provided us with qualitatively new information on star and planet formation and small bodies in our Solar System. For example, in the observations of protoplanetary disks, ring-like structures have been commonly found and the structures with the scale of several-AU are discovered in several systems. In our solar system, 60km pixel-scale non-uniform brightness distribution and the rotation of the asteroid Juno are detected. Spatially-resolved thermal mapping of Europa icy surface enables us to search for thermal anomaly in possible plume source regions. As of Cycle 4, Solar observations are available, enabling us, for example, to determine the physical parameters of plasmoid quantitatively. In this session, we overview the latest results of ALMA observations in the field of planetary sciences. We also accept any theoretical and experimental works that are closely related to the observations and discuss the impact on the planetary science community.
