    K2-31B, a Grazing Transiting Hot Jupiter on a 1.26-day Orbit around a Bright G7V Star
    We report the discovery of K2-31b, the first confirmed transiting hot Jupiter detected by the K2 space mission. We combined K2 photometry with FastCam lucky...

    K2-399 b is not a planet: The Saturn that wandered through the Neptune desert is actually a hierarchical eclipsing binary
    Context. The transit technique has been very efficient over the past decades in detecting planet-candidate signals. The so-called statistical validation...

    K2-99: a subgiant hosting a transiting warm Jupiter in an eccentric orbit and a long-period companion
    We report the discovery from K2 of a transiting planet in an 18.25-d, eccentric (0.19 ± 0.04) orbit around K2-99, an 11th magnitude subgiant in Virgo. We...
