The JASMINE mission

Professor Daisuke Kawata , University College London
The Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a selected ISAS/JAXA science space mission. JASMINE has two main science goals. One is Galactic archaeology with a Galactic Centre survey, which aims to reveal the Milky Way’s central core (Rgc<~200 pc) structure and formation history from Gaia-level (?25 ?as) astrometry in the near-infrared (NIR) Hw-band (1.0–1.6?m). The other is an exoplanet survey, which aims to discover transiting Earth-like exoplanets in the habitable zone from NIR time-series photometry of M dwarfs when the Galactic Centre is not accessible. JASMINE will be the first dedicated NIR astrometry space mission and provide precise astrometric information on the stars in the Galactic Centre, taking advantage of the significantly lower extinction in the NIR. The precise astrometry is obtained by taking many short-exposure images. Hence, the JASMINE Galactic Centre survey data will be valuable for studies of exoplanet transits, asteroseismology, variable stars, and microlensing studies, including discovery of (intermediate-mass) black holes. We introduce the mission and review the science prospects of JASMINE. Those unable to attend the colloquium in person are invited to participate online through Zoom (Meeting ID: 942 0262 2849, passcode 792771) using the link: https://eu02web.zoom-x.de/j/94202622849?pwd=dGlPQXBiUytzY1M2UE5oUDRhbzNOZz09 During his visit to Heidelberg, Professor Kawata will be available for meetings by arrangement with his host, Michael Biermann (biermann@ari.uni-heidelberg.de).
