Description
This proposal is a resubmission of an accepted RXTE AO 11 proposal. Our aim is to test evolutionary and type I burst models with the observed type I X-ray burst behaviour of the bright ultra-compact binary system 4U 1820-30. The short orbital period suggests that the companion white dwarf is hydrogen deficient, with evolutionary models predicting a composition of either pure helium or a small amount of hydrogen (~5-35% by mass). We propose to compare observed type I burst properties with detailed X-ray burst models, constraining the composition of the donor star and testing evolutionary models.

    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

    ANDES, the high resolution spectrograph for the ELT: science goals, project overview, and future developments
    The first generation of ELT instruments includes an optical-infrared high resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion Echelle Spectrograph). ANDES consists of three fibre-fed spectrographs ([U]BV, RIZ, YJH) providing a spectral resolution of ∼100,000 with a minimum simultaneous wavelength

    An overview of the preliminary optical design of the European Solar Telescope (EST)
    The European Solar Telescope (EST) is a 4-m class-solar telescope that will become part of the next generation of groundbased facilities. Located at the "Observatorio del Roque de los Muchachos" in La Palma (Spain), it will be aimed to study the magnetic connectivity of the solar atmosphere with high spatial and temporal resolution.
