Description
We present in this contribution a review of recent results of parameters of massive OB stars in the Milky Way, the Magellanic Clouds and nearby spirals. The review is timely because of the strong lowering of the temperature scale of Galactic OB stars produced by the new model atmospheres, including sphericity, blanketing and mass-loss, that are also discussed, and because of the boost suffered by extragalactic stellar physics in the last years. The effects on the determination of mass-loss and the Modified Wind Momentum-Luminosity Relationship are discussed, and a comparison with evolutionary models is provided. We finally present a comparison of abundances from OB stars and H II regions in Orion and M 33.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    MAAT: an IFU for GTC optimized using spectrograph wavefront measurements and superoptimization
    The Mirror-slicer Array for Astronomical Transients (MAAT) is an IFU now being manufactured for the OSIRIS spectrograph on the 10.4-m GRANTECAN (GTC) telescope at La Palma. It is based on the Advanced Image Slicer (AIS) concept as are MUSE and KMOS on the VLT (among many others). Very significant changes to the design had to be made due in part to

    JWST observations of Chiron: A unique active Centaur beyond 18 AU
    Chiron is the second-largest Centaur, with an effective diameter of 210 km, and is among the most well-studied minor bodies in the middle and outer Solar System. Notably, Chiron belongs to the enigmatic subpopulation of active Centaurs and has displayed cometary activity several times since its discovery. In March 2021, Chiron underwent an outburst
