    Nodal precession of a hot Jupiter transiting the edge of a late A-type star TOI-1518
    TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b ~ 0...

    The K2-ESPRINT project. VI. K2-105 b, a hot Neptune around a metal-rich G-dwarf
    We report on the confirmation that the candidate transits observed for the star EPIC 211525389 are due to a short-period Neptune-sized planet. The host star...

    TOI-2285b: A 1.7 Earth-radius planet near the habitable zone around a nearby M dwarf
    We report the discovery of TOI-2285b, a sub-Neptune-sized planet transiting a nearby (42 pc) M dwarf with a period of 27.3 d. We identified the transit signal...
