Descripción
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 imaging and FIES and HARPS high-resolution spectroscopy to confirm the planetary nature of the transiting object and derived the system parameters. K2-31b is a 1.8-Jupiter-mass planet on a 1.26-day orbit around a G7 V star ({M}\star =0.91 M ⊙, {R}\star =0.78 R ⊙). The planetary radius is poorly constrained (0.7 < R p < 1.4 R Jup),15 owing to the grazing transit and the low sampling rate of the K2 photometry.16

    A giant planet transiting a 3-Myr protostar with a misaligned disk
    Astronomers have found more than a dozen planets transiting stars that are 10–40 million years old 1, but younger transiting planets have remained elusive. The lack of such discoveries may be because planets have not fully formed at this age or because our view is blocked by the protoplanetary disk. However, we now know that many outer disks are

    WEAVE First Light Observations: Origin and Dynamics of the Shock Front in Stephan's Quintet
    We present a detailed study of the large-scale shock front in Stephan's Quintet, a by-product of past and ongoing interactions. Using integral-field spectroscopy from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), recent 144 MHz observations from the LOFAR Two-metre Sky Survey, and archival data from the Very Large
