Description
The intensity distribution of the penumbra at different stages of evolution has been analyzed. The results have been different for both evolved and primitive penumbras. While the former present almost symmetrical, single-peaked histograms, the same does not occur for the latter, their distributions being, preferentially, asymmetrical or double-peaked. These results are interpreted in terms of bright and dark elements. Thus, an evolutionary process has been proposed to explain the diverse characteristics found at the different stages.

    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
