    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...

    The Intergalactic Stellar Population from Mergers of Elliptical Galaxies with Dark Matter Halos
    We present simulations of dry-merger encounters between pairs of elliptical galaxies with dark matter halos. The aim of these simulations is to study the...

    The Internal Proper Motion Kinematics of NGC 346: Past Formation and Future Evolution
    We investigate the internal kinematics of the young star-forming region NGC 346 in the Small Magellanic Cloud (SMC). We used two epochs of deep F555W and F814W...

    The intriguing H I gas in NGC 5253: an infall of a diffuse, low-metallicity H I cloud?
    We present new, deep H I line and 20-cm radio-continuum data of the very puzzling blue compact dwarf galaxy NGC 5253, obtained with the Australia Telescope...
