Descripción
An RXTE observation of 4U 1636-536 taken on March 10th, 2009, revealed two type I X-ray bursts from this well studied neutron star low-mass X- ray binary (NS-LMXB). The recurrence time (wait time) between the two events, 5.4 minutes, is the shortest observed in any NS-LMXB. The average spectrum exhibited by both bursts was thermal. We performed time- resolved spectroscopy along the bursts, using a black body model and an absorbing column density of 0.3e22 cm-2 (Fiocchi et al.

    Local seeing analysis for the European Solar Telescope
    The European Solar Telescope (EST) will be built at the Observatorio del Roque de los Muchachos, a site known for its excellent atmospheric seeing conditions. The fundamental design of EST lies on two premises to improve the local seeing: placing the primary mirror as far as possible from the ground layer and using an open-air configuration. In

    First on-sky tests of LQG control for a 10m-class telescope: prelude on the Gran Telescopio Canarias adaptive optics system
    The Gran Telescopio Canarias (GTC) is being equipped with an Adaptive Optics (AO) system, developed by the Instituto de Astrofísica de Canarias (IAC). The Institut d'Optique Graduate School-Laboratoire Charles Fabry (IOGS-LCF), through a collaboration with the IAC, integrated some high performance control solutions. In this proceeding, we present
