ScopeThe Atacama Large Millimeter/Submillimeter Array (ALMA) started its science operation in 2011, and long-baseline observations have been available since 2014. With its high sensitivity and spatial resolution, ALMA has provided us with transformational information on star and planet formation and our Solar System bodies. 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, scientific achievements which utilizing high capability of ALMA such as detections of new molecules on Titan and Pluto and derivation of 3-D structure of the gas giants with continuum observation have been reported. As of Cycle 4, Solar observations have become 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 broad field of planetary sciences. We also accept theoretical and experimental works that are closely related to the observations and discuss the impact on the planetary science community.
