[PEM11-20] Searching for Exoplanets around M-type stars using JASMINE

Keywords:Transit, Habitable planets

JASMINE is a satellite mission of ISAS/JAXA that performs astrometry of the Galactic center and transit search around the habitable zone around mid M-type stars. JASMINE has a 36cm aperture, 1-1.6μm near-infrared astrometric and precision photometric instrument. We expect larger photon collecting capability than TESS for M-type stars and better photometric accuracy than ground telescopes, which will be used to search for Earth-like planets in the habitable zone around mid M-type stars (Teff ~ 3000K). This specification is advantageous for the search for terrestrial planets in the habitable zone (0.2-0.3% depth) around mid M-type stars. However, the field of view is too narrow for a blind survey, so pre-target selection is quite important for Pointing Individual Target (PIT)-type surveys. I would also like to discuss instrumental uniqueness, such as a flat correction lamp.
