Abstract: We introduce our project of simultaneous Subaru/MAGNUM observations of extrasolar planetary transits, designed for (i) transmission spectroscopy in order to search for absorption features due to planetary exospheres, and (ii) precise radial velocity measurements in order to measure the Rossiter-McLaughlin effect. Our observing strategy of extrasolar planetary transits is to conduct simultaneous spectroscopic/photometric (optical+IR) observations, using the HDS of the Subaru 8.2-m telescope at Mauna Kea and the MAGNUM 2-m telescope at Haleakala, both in Hawaii. The simultaneous photometric monitoring will eliminate any uncertainty due to orbital ephemeris in our results, and it will also allow an independent determination of the transit depth and the limb-darkening parameters. In this manuscript, we detail our ability of observations to characterize transiting extrasolar planets, and also introduce previous studies, current status and prospects of the project.
