| Abstract: | Protoplanetary disks are the most probable sites where planet formation takes place. According to theory, planet formation
in protoplanetary disks should show remarkable signatures, such as a gap/hole or a spiral structure. In fact, recent high-angular
and high-sensitivity observations in millimeter and submillimeter wavelengths, as well as optical/near-IR wavelengths, have
shown such structures in protoplanetary disks. Two particular examples of such disks around AB Aurigae and HD 142527 are discussed
here, with an emphasis on results obtained using the Submillimeter Array. These disks—and their probable planet formation—will
be very important future targets for ALMA to study the physical process of planet formation in detail. |
