    Results of diffraction effects in segmented mirrors: co-phasing with integrated curvature signal
    In this paper, we study the ability of a curvature sensor (CS) to measure co-phasing errors in a segmented primary mirror. We study a new fast and low memory-consuming algorithm based on the definition of an integrated curvature signal. This signal results from the integration of the CS response in enclosures matching the shapes of the segments in

    Rayleigh guide star AO demonstrator for the 4.2m William Herschel Telescope
    An experimental Adaptive Optics system utilizing a low-altitude Rayleigh Laser Guide Star is presented. The current status of the project is described together with plans for future work, with the ultimate goal of providing demonstration Rayleigh LGS AO science on the 4.2m William Herschel Telescope. The implementation of the demonstration system

    Quantitative Spectral Analysis of Early B-Type Supergiants in the Sculptor Galaxy NGC 300
    The spectra of two early B-type supergiant stars in the Sculptor spiral galaxy NGC 300 are analyzed by means of non-LTE line-blanketed unified model atmospheres, aimed at determining their chemical composition and the fundamental stellar and wind parameters. For the first time, a detailed chemical abundance pattern (He, C, N, O, Mg, and Si) is

    Performance of the first-light adaptive optics system of LBT by means of CAOS simulations
    This presentation reports the numerical simulations we have done in order to evaluate the performance of the first-light AO system of LBT. The simulation tool used for this purpose is the Software Package CAOS, applicable for a wide range of AO systems and for which a brief recall of the main features is made. The whole process of atmospheric

    OSCA, an Optimized Stellar Coronagraph for Adaptive optics: Description and first light
    We describe a coronagraph facility built for use with the 4.2 metre William Herschel Telescope (WHT) and its adaptive optics system (NAOMI). The use of the NAOMI adaptive optics system gives an improved image resolution of ~0.15 arcsec at a wavelength of 2.2 microns. This enables our Optimised Stellar Coronagraph for Adaptive optics (OSCA) to null

    On the Origin of the Dispersion in the 7Li/6Li Ratio in the ISM
    Measurements of the 7Li/6Li ratio in the local interstellar medium (ISM) towards o Per and ζ Per by Knauth et al. (2000, AAA 073.131.129) show clouds with a range from near 2 (a value which points to GCR production by spallation or alpha + alpha to near 11 (the solar system value). These values can be very well accounted for within our model of
