Descripción
Observations with the Wide Field Cameras on BeppoSAX revealed seven type-I X-ray bursters that failed to exhibit significant levels of persistent emission. The constraints on the persistent luminosity simultaneous to the bursts are sometimes lower than what is commonly observed for type-I bursters. Therefore, a new class of objects is suggested. Chandra ACIS-S follow-up observations that were carried out on five of them showed a persistent emission level of 10^(32-33) erg/s. An observational overview of these sources is presented.

    Conceptual design of the infrared integral field spectropolarimeter for the European Solar Telescope
    The European Solar Telescope (EST) will be Europe's most ambitious ground-based infrastructure in solar physics. It will have a primary mirror with a diameter of 4.2m, which will make it the largest in Europe, and of identical aperture as the largest solar telescope available worldwide, namely the Daniel K. Inouye Telescope (DKIST) installed at the

    Detector upgrade in EMIR@GTC: on-sky performances
    EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. Since the beginning, the EMIR performances have been severely hampered by the many instabilities in the infrared detector, a 2048x2048 Hawaii2, built with the old original technology of the Teledyne Hawaii series. Despite of this, the instrument has proven to be powerful

    ANDES, the high-resolution spectrograph for the ELT: RIZ spectrograph preliminary design
    We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument. It is a fiber-fed high-resolution, high-stability spectrograph. Its design follows the guidelines of successful predecessors such as HARPS and ESPRESSO. In this paper we present the status of the spectrograph at the preliminary design
