| Outline of Final Research Achievements |
A rocky planet acquires mass through multiple giant impact events. We consider silica, which is produced only under a high temperature and high pressure condition, as a tracer of the giant impacts and investigate the impact events by observing a shape and time variation of silica feature in 10 microns radiated from young exo-planets with the mid-infrared instrument MIMIZUKU. MIMIZUKU can obtain spectra in the 10-micron band with high accuracy by a field stacker unit. In this study, we have developed sensor units, opto-mechanical units, and the field stacker unit of MIMIZUKU and successfully completed integrated tests after assembling them into a vacuum dewar and an optical system. We also have planned spectroscopic monitoring observations with MIMIZUKU on the Subaru telescope.
