Description
ESPRESSO, the Echelle SPectrograph for Rocky Exoplanets and Stable Spectroscopic Observations, will combine the efficiency of modern echelle spectrograph design with extreme radial-velocity precision. It will be installed on ESO's VLT in order to achieve a gain of two magnitudes with respect to its predecessor HARPS, and the instrumental radialvelocity precision will be improved to reach cm/s level. Thanks to its characteristics and the ability of combining incoherently the light of 4 large telescopes, ESPRESSO will offer new possibilities in various fields of astronomy. The main scientific objectives will be the search and characterization of rocky exoplanets in the habitable zone of quiet, nearby G to M-dwarfs, and the analysis of the variability of fundamental physical constants. We will present the ambitious scientific objectives, the capabilities of ESPRESSO, and the technical solutions of this challenging project.

    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
