[P-PS15] New developments of planetary sciences with ALMA

Sun. May 22, 2016 3:30 PM - 5:00 PM A02 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Munetake Momose(The College of Science, Ibaraki University), Satoshi Okuzumi(Graduate School of Science, Tokyo Institute of Technology), Hiroshi Kobayashi(Department of Physics, Nagoya University), Hideo Sagawa(Faculty of Science, Kyoto Sangyo University), Tetsuo Hasegawa(National Astronomical Observatory of Japan, National Institutes of Natural Sciences), Chair:Satoshi Okuzumi(Graduate School of Science, Tokyo Institute of Technology)

The Atacama Large Millimeter/Submillimeter Array (ALMA) starated its science operation in 2011. Thanks to its high sensitivity and mapping capability, ALMA has revealed detailed structure of nearby protoplanetary disks, providing us with new informations about the formation of a planetary system in general. There are also interesting publications about observations of HNC and HC3N in Titan atmosphere, HDO and SOx in Venus atmosphere, opening new frontiers in the planetary atmospheric sciences. In particular, long-baseline campaign observations made in 2014 brought us spectacular images. Ring-gap structure in the protoplanetary disk around the young star HL Tau is discovered with 4au resolution, while non-uniform brightness distribution and rotating motion of the asteroid Juno is mapped with 60km pixel-size in the image. These results demonstrate that ALMA will be a powerful tool for exploring disks around young stars and objects in the solar system. This session will accept not only the observational studies with ALMA but also any theoretical and experimental works that are closely related to the observations, and planetary sciences with ALMA will be discussed comprehensively.
