    A super-Earth on a close-in orbit around the M1V star GJ 740. A HADES and CARMENES collaboration
    Context. M-dwarfs have proven to be ideal targets for planetary radial velocity (RV) searches due to their higher planet-star mass contrast, which favors the...

    A super-Earth orbiting near the inner edge of the habitable zone around the M4.5 dwarf Ross 508
    We report the near-infrared radial velocity (RV) discovery of a super-Earth planet on a 10.77 d orbit around the M4.5 dwarf Ross 508 (J mag = 9.1). Using...

    A super-Earth orbiting the nearby M dwarf GJ 536
    We report the discovery of a super-Earth orbiting the star GJ 536 based on the analysis of the radial-velocity time series from the HARPS and HARPS-N...

    A system of three transiting super-Earths in a cool dwarf star
    We present the detection of three super-Earths transiting the cool star LP415-17, monitored by K2 mission in its 13th campaign. High-resolution spectra obtained...

    A temperature inversion with atomic iron in the ultra-hot dayside atmosphere of WASP-189b
    Temperature inversion layers are predicted to be present in ultra-hot giant planet atmospheres. Although such inversion layers have recently been observed in...

    A tentative detection of He I in the atmosphere of GJ 1214 b
    The He I λ10833 Å triplet is a powerful tool for characterising the upper atmosphere of exoplanets and tracing possible mass loss. Here, we analysed one transit...

    A transit timing variation observed for the long-period extremely low-density exoplanet HIP 41378 f
    HIP 41378 f is a temperate 9.2 ± 0.1 R ⊕ planet with period of 542.08 d and an extremely low density of 0.09 ± 0.02 g cm -3. It transits the bright star HIP...

    A transiting super-Earth close to the inner edge of the habitable zone of an M0 dwarf star
    We present a super-Earth orbiting close to the inner edge of the habitable zone of the cool dwarf star K2-286 (EPIC 249889081), detected with data from the K2...

    A transmission spectrum of the planet candidate WD 1856+534 b and a lower limit to its mass
    The cool white dwarf WD 1856+534 was found to be transited by a Jupiter-sized object with a mass at or below 14 M Jup. We used the GTC telescope to obtain and...
