    Discovery of the polluting stars that form the second stellar generation in globular clusters
    Historically, globular clusters (GCs) have been used as laboratories for studying stellar evolution, because it was thought that all the stars in a globular...

    Dissecting light bridges: the stratification of their physical properties in geometric height
    Light bridges are elongated and bright structures protruding into the umbra of sunspots. The presence of light bridges has a significant role in the evolution...

    Dissecting the Spitzer color-magnitude diagrams of extreme LMC AGB stars.
    For the first time we use self-consistent evolutionary models of low-and intermediate-mass stars (1-8 solar masses) coupled with theoretical dust formation...

    Do we need a galactic disc to form stars?
    Early-type galaxies (ETGs) were historically considered as ‘boring’ objects by astronomers. This galaxy category encompasses lenticular and elliptical galaxies...

    Downflowing umbral flashes as evidence of standing waves in sunspot umbrae
    Umbral flashes are sudden brightenings commonly visible in the core of some chromospheric lines. Theoretical and numerical modeling suggests that they are...

    Dual dust chemistry around evolved stars of the Large Magellanic Cloud
    During the final stages of their lives, stars with masses between one and eight times the mass of the Sun evolve along the asymptotic giant branch (AGB). AGB...

    Dust in the central parsecs of unobscured AGN provides more challenges to the torus
    The black holes at the centres of galaxies are the most mysterious objects in the Universe, not only because of the huge quantities of material within them...

    Early evolution of disrupted asteroid P/2016 G1 (PANSTARRS)
    We present deep imaging observations of activated asteroid P/2016 G1 (PANSTARRS) using the 10.4m Gran Telescopio Canarias ( GTC)  from 2016 late April to early...

    Earth’s albedo variations 1998-2014 as measured from ground-based earthshine observations
    The Earth’s albedo is a fundamental climate parameter for understanding the radiation budget of the atmosphere. It has been traditionally measured from space...
