We propose high-contrast imaging exploration around two young stellar objects (YSOs; ∼1–10 Myr) in Taurus star forming region, which harbor close-in planets, using Subaru/SCExAO+CHARIS in broad-band mode. Previous high-contrast imaging set higher priority mainly on disks that may have induced by planet formation, but here we propose another selection criteria of inner planets, which means our proposed targets have already started planet formation. This high-contrast imaging enables us to find giant planets down to ∼1 M_J beyond a few 10 au around YSOs. A detection will be a great discovery of very young planet and multiple planetary system. Even if we do not detect any companion candidates, detection limits will be a direct and crucial constraint on migration mechanism of the inner planets. Therefore our proposed observation can be, if any results, published and will be useful for future target selection of high-contrast imaging from transit/radial velocity surveys such as TESS.
