    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 systematic bias in template-based radial velocity extraction algorithms
    Context. The radial velocity (RV) method plays a key role in modern-day astrophysics. One of the most common techniques for extracting precise RVs from state-of...

    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 multiplanet system in the 61 Myr old association Theia 116
    Observing and characterizing young planetary systems can aid in unveiling the evolutionary mechanisms that sculpt the mature exoplanet population. As an all-sky...

    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...

    A universal method for solar filament detection from Hα observations using semi-supervised deep learning
    Filaments are omnipresent features in the solar atmosphere. Their location, properties, and time evolution can provide important information about changes in...
