Outline of Final Research Achievements

Most stars form as multiples. Although the planet formation around a single star has been well proceeded, that around multiples remains many unexplained mysteries. Therefore, high resolution imaging observations of binary disks are conducted in order to gain better understanding of planet formation around multiples.
As one of the unique result, polarization imaging data of binary disks with non-axisymmetric features have been obtained. By comparisons with radio data including ALMA, origin of the non-axisymmetric features are analyzed.
