The importance of binary stars
Stars are mostly found in binary and multiple systems, as at least 50% of all solar-like stars have companions - a fraction that goes up to 100% for the most...
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...
