Description
U,B,V,R,I and simultaneous near infrared J,H,K light curves of the RS CVn system ER Vul are presented. A study of the mean levels compared to other years indicates that the system is highly variable, giving evidence that important changes occur over one month. Colours show an ultraviolet and infrared excess. There seems to be a contribution from a hot plasma in the observed fluxes, with temperatures between 104 - 5×104K.

    The TESS TTV Follow-up Program: Revealing Volatile-Rich Terrestrial Planets Around M Stars
    Models predict that water-rich planets may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Recent JWST observations of sub-Neptune sized planets orbiting nearby M dwarfs found atmospheres enriched in CH4, CO2 and H2O, but the enrichment mechanism is debated. To answer this question

    The instrumentation plan of the 10.4m GTC telescope
    The 10.4m Gran Telescopio Canarias (GTC) was designed to be a versatile telescope, able to serve a wide scientific community. To this aim, various focal stations have been equipped, including a Cassegrain, two Nasmyth foci, and four folded-Cassegrain stations. This allows an ambitious instrumentation plan to be developed. We present the latest

    Design and fabrication of fold mirror (M3) system for New Robotic Telescope
    The New Robotic Telescope (NRT) is an autonomous telescope that can operate multiple instruments at the Cassegrain focal station and the straight-through port. The optical beam is directed to the ports by a fold mirror subsystem in the focal station assembly. The fold mirror is elliptical in shape, manufactured by Instituto Nazionale di Astrofisica
