Direct Imaging of DM Tau in NIR Band
Circumstellar disks are often observed to be surrounding young stars, especially T Tauri stars. The composition and structure of circumstellar disks have essential effect in the formation of planets. Therefore, investigation of such disks is quite beneficial for us to understand the formation process of the planetary system. In this presentation, I will show the near infrared observation of DM Tau from HiCIAO instrument mounted on Subaru Telescope. This T Tauri star is located in Taurus star formation region which is one of the nearest star formation regions from the Solar System. Hence it is easy to resolve the detailed structure of its disk. I believe this research is quite helpful to figure out the scenario of disk evolution and the ongoing planet formation in that disk.
