" mm and submm interferometric observations of protoplanetary disks "

Nagayoshi Ohashi

(Subaru Telescope)


Protoplanetary disks, which are formed as by-products of star formation, are the most probable site of planet formation. In fact, more exoplanets have been discovered, urging us toward detailed studies of protoplanetary disks. Because these disks are very compact with a typical size of 100 AU, high angular resolution observations, such as those using mm and submm interferometers are the key to study them in detail. In my talk, I will present recent observations of protoplanetary disks around protostars as well as pre-main-sequence stars.


Seminars are also held at JAC, CFHT, and IfA.
