Description
The central star of ETHOS 1 is known to be a post-common-envelope binary. Simultaneous modelling of newly-acquired light and radial velocity curves reveal the binary to comprise of a hot and massive pre-white dwarf with a low-mass main-sequence companion. Preliminary results indicate that the nebular progenitor is one of the most massive known amongst the population of binary central stars. As such, the central binary of ETHOS 1 could potentially be a type Ia supernova progenitor via the single-degenerate channel.

    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
