    Misaligned spin-orbit in the XO-3 planetary system?
    The transiting extrasolar planet XO-3b is remarkable, with a high mass and eccentric orbit. These unusual characteristics make it interesting to test whether...

    Missing large-angle correlations versus even-odd point-parity imbalance in the cosmic microwave background
    Context. The existence of a maximum correlation angle (θ max ≳ 60°) in the two-point angular temperature correlations of cosmic microwave background (CMB)...

    Mixing by internal waves. III. Li and Be abundance dependence on spectral type, age and rotation
    In this paper we deal with the problem of the generation of internal waves at the bottom of convective zone in solar-type stars, and with the transport process...

    MOA-2022-BLG-033Lb, KMT-2023-BLG-0119Lb, and KMT-2023-BLG-1896Lb: Three low mass-ratio microlensing planets detected through dip signals
    Aims. We examined the anomalies in the light curves of the lensing events MOA-2022-BLG-033, KMT-2023-BLG-0119, and KMT- 2023-BLG-1896. These anomalies share...

    Mode visibilities in radial velocity and photometric Sun-as-a-star helioseismic observations
    We analyze more than 5000 days of high-quality Sun-as-a-star, radial velocity GOLF and photometric VIRGO/SPM helioseismic observations to extract precise...

    Model comparison for the density structure along solar prominence threads
    Context. Quiescent solar prominence fine structures are typically modelled as density enhancements, called threads, which occupy a fraction of a longer magnetic...

    Modeling dust emission in PN IC 418
    We investigated the infrared (IR) dust emission from PN IC 418, using a detailed model controlled by a previous determination of the stellar properties and the...

    Modeling LiI and KI sensitivity to Pleiades activity.
    We compare schematic modeling of spots and plage on the surface of cool dwarfs with Pleiades data to assess effects of magnetic activity on the strengths of the...
