    The Impact of Enhanced He and CNONa Abundances on Globular Cluster Relative Age-Dating Methods
    The impact that unrecognized differences in the chemical patterns of Galactic globular clusters (GGCs) have on their relative age determinations is studied. The...

    The impact of strong recombination on temperature determination in planetary nebulae
    The long-standing difference in chemical abundances determined from optical recombination lines and collisionally excited lines raises questions about our...
  • Publication
    The impact of two massive early accretion events in a Milky Way-like galaxy: repercussions for the buildup of the stellar disc and halo
    We identify and characterize a Milky Way-like realization from the Auriga simulations with two consecutive massive mergers $\sim 2$ Gyr apart at high redshift...

    The Influence of 10 Unique Chemical Elements in Shaping the Distribution of Kepler Planets
    The chemical abundances of planet-hosting stars offer a glimpse into the composition of planet-forming environments. To further understand this connection, we...

    The Infrared Eye of the Wide-Field Camera 3 on the Hubble Space Telescope Reveals Multiple Main Sequences of Very Low Mass Stars in NGC 2808
    We use images taken with the infrared channel of the Wide Field Camera 3 on the Hubble Space Telescope to study the multiple main sequences (MSs) of NGC 2808...

    The initial mass function of a massive relic galaxy
    Massive relic galaxies formed the bulk of their stellar component before z ˜ 2 and have remained unaltered since then. Therefore, they represent a unique...

    The intense production of silicates during the final AGB phases of intermediate mass stars
    Context. The formation of silicates in circumstellar envelopes of stars evolving through the asymptotic giant branch (AGB) is still highly debated given the...

    The Interaction of Asymptotic Giant Branch Stars with the Interstellar Medium
    We study the hydrodynamical behavior of the gas expelled by moving asymptotic giant branch stars interacting with the interstellar medium (ISM). Our models...

    The interaction of the halo around the butterfly planetary nebula NGC 650-1 with the interstellar medium
    With its bright and wide equatorial waist seen almost edge-on (`the butterfly body') and the faint and broad bipolar extensions (`the butterfly wings'), NGC 650...
