Description
We present preliminary results of a brown dwarf (BD) detection in a ˜1000 star sample monitored with the ongoing PennState-Toruń Centre for Astronomy Planet Search. Contrary to most other projects, our sample contains a substantial fraction of evolved stars ranging from sub-giants up to bright giants, allowing us to study companions to stars more massive than ˜1.5 M⊙. For Main Sequence stars, this limit is set by effective temperature and rotation velocity. Our relatively long list of about a dozen candidates suggests that the BD frequency may rise with stellar mass as it does in the case of planets \citep{lm2007}.

    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
