| 内容記述 | Circumstellar disks have been thoroughly studied with MIR wavelengths because MIR traces the critical components of disks, such as life habitable zone of protoplanetary disks and debris disk. As a result, many characteristics of the disk evolution have been revealed e.g., disk lifetime, dust growth, transitional disk. However, previous studies are only in the solar neighborhood (D less than or equal to 2 kpc). Whether protoplanetary disks throughout the Galaxy evolve similarly to those in the solar neighborhood is of great interest. As the next step, I propose studies of circumstellar disks in the Galactic scale. Due to low sensitivities of previous MIR instruments, studies beyond the solar neighborhood have not been possible. With the high sensitivity of SPICA MCS, approximately 1 μJy at 10 and 20 μm, excess of circumstellar disks can be fully characterized and disk lifetime can be precisely estimated. Very wide field of view (approximately 5′ × 5′) is also a great advantage compared to the other future instruments, such as JWST MIRI and TMT MICHI. Protoplanetary disks of sub-solar mass stars and even debris disks of intermediate-mass stars can be detected. Eventually, these kind of studies will be connected to the search of life throughout the Galaxy. | |||||||||
