    Evidence for transit-timing variations of the 11 Myr exoplanet TOI-1227 b
    TOI-1227 b is an 11 Myr old validated transiting planet in the middle of its contraction phase, with a current radius of 0.85 R j. It orbits a low-mass pre-main...

    Evidence of intra-binary shock emission from the redback pulsar PSR J1048+2339
    We present simultaneous multiwavelength observations of the 4.66 ms redback pulsar PSR J1048+2339. We performed phase-resolved spectroscopy with the Very Large...

    Examining the orbital decay targets KELT-9 b, KELT-16 b, and WASP-4b, and the transit-timing variations of HD 97658 b
    Context. Tidal orbital decay is suspected to occur for hot Jupiters in particular, with the only observationally confirmed case of this being WASP-12b. By...

    Exceptional outburst of the blazar CTA 102 in 2012: the GASP-WEBT campaign and its extension
    After several years of quiescence, the blazar CTA 102 underwent an exceptional outburst in 2012 September-October. The flare was tracked from γ-ray to near...

    Exploring the lower mass function in the young open cluster IC 4665
    We present a study of the young (30-100 Myr) open cluster IC 4665 with the aim to determine the shape of the mass function well into the brown dwarf regime. We...
