  • Preliminary analysis of the Hayabusa2 samples returned from C-type asteroid Ryugu

    C-type asteroids1 are considered to be primitive small Solar System bodies enriched in water and organics, providing clues to the origin and evolution of the Solar System and the building blocks of life. C-type asteroid 162173 Ryugu has been characterized by remote sensing2-7 and on-asteroid measurements8,9 with Hayabusa2 (ref. 10). However, the

  • Rapid contraction of giant planets orbiting the 20-million-year-old star V1298 Tau

    Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about several hundred million years1,2. These theoretical expectations remain untested so far as the detection and characterization of very young planets is extremely

  • 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 from the Transiting Exoplanet Survey Satellite photometric data, which we confirmed with ground-based photometric observations using the multiband imagers MuSCAT2 and MuSCAT3. Combining these

  • Detections of solar-like oscillations in dwarfs and subgiants with Kepler DR25 short-cadence data

    During the survey phase of the Kepler mission, several thousand stars were observed in short cadence, allowing for the detection of solar-like oscillations in more than 500 main-sequence and subgiant stars. These detections showed the power of asteroseismology in determining fundamental stellar parameters. However, the Kepler Science Office

  • First models of the s process in AGB stars of solar metallicity for the stellar evolutionary code ATON with a novel stable explicit numerical solver

    Aims: We describe the first s-process post-processing models for asymptotic giant branch (AGB) stars of masses 3, 4, and 5 M⊙ at solar metallicity (Z = 0.018) computed using the input from the stellar evolutionary code ATON. Methods: The models are computed with the new code SNUPPAT (S-process NUcleosynthesis Post-Processing code for ATON), which
