title: TMT/MICHI observations of disks and planets authors: M. Honda, C. Packham, Y. K. Okamoto, H. Kataza, and the MICHI team abstract: We are proposing a mid-infrared instrument MICHI (Mid-IR Camera, High-disperser, & IFU Spectrograph) for the TMT (Thirty Meter Telescope). In this poster, we will show the current MICHI concepts and the proposed science cases of disks and exoplanets. We strongly welcome your inputs.
