| Outline of Final Research Achievements |
We made high-resolution mid-infrared imaging observations of the protoplanetary disks around Herbig Ae/Be stars mainly using mid-IR instruments COMICS on Subaru Telescope. Based on our continuous observational studies, we established a new interpretation that the disks around the group I Herbig Ae/Be stars are actually transitional disks. In addition, we found that the misalignment of the inner and outer disks affects the mid-infrared disk morphology significantly.
Furthermore, we have been developping an internal cold chopper system for the future
next-generation ground-based mid-IR facility/instrument. A first test model was designed and fabricated for detailed analysis and trouble shooting. We found some problems on the first test model, but also noticed that even this model can be used for the chopping observations. We are now making a second test model and also planning an on-sky test observing with these new cold chopper.
