    Searching for hot water world candidates with CHEOPS: Refining the radii and analysing the internal structures and atmospheric lifetimes of TOI-238 b and TOI-1685 b
    Studying the composition of exoplanets is one of the most promising approaches to observationally constrain planet formation and evolution processes. However...

    Searching for the orbital period of the ultraluminous X-ray source NGC 1313 X-2
    We analysed the longest phase-connected photometric data set available for NGC 1313 X-2, looking for the ˜6-day modulation reported by Liu et al.. The folded B...

    Shape and spin determination of Barbarian asteroids
    Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are...
  • Publication
    Shape and spin-state model of tumbling asteroid (319) Leona
    Context. Stellar occultations by asteroids observed from several stations are routinely used to reconstruct the asteroid's sky-plane projections. Together with...

    Short-term variability of the transitional pulsar candidate CXOU J110926.4‑650224 from X-rays to infrared
    CXOU J110926.4‑650224 is a candidate transitional millisecond pulsar (tMSP) with X-ray and radio emission properties reminiscent of those observed in confirmed...

    Signal detection for spectroscopy and polarimetry
    The analysis of high spectral resolution spectroscopic and spectropolarimetric observations constitutes a very powerful way of inferring the dynamical...

    Silicon in the dayside atmospheres of two ultra-hot Jupiters
    Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two...
