Research Field

  • Cool stars, our Galaxy, astronomical instruments, and exoplanet searches

Brief Introduction of Research

  • I am interested in the origin, time-dependence, and morphology of winds from cool stars.
    I work at UV, optical, far-infrared, and radio wavelengths for the studies.
    I am also interested in the structure and kinematics of our Milky Way Galalxy.
    I employ infrared and radio observations for the studies.
    I also work on astronomical instrumentation. I have been involved in an optical high resolution spectrograph for the 188-cm telescope at Okayama Astrophysical Observatory. As a consequence, I am engaged in some searches for exoplanets using the telescope and the spectrograph.
