Solar system and exoplanets
Solar system and exoplanet research at Gemini spans a wide range of topics from the chemical structure of bodies within the solar system to the possibility of life beyond it. Research activities aim to understand the formation of exoplanets and our own Solar System in the same context. The present day Trans-Neptunian population may be viewed as a highly evolved (and very local) circumstellar disk, with broad implications for the formation of planets in disks around other stars.

  • Stellar astrophysics
    Stellar Astrophysics research at Gemini encompasses many aspects of stars, "failed" stars and ex-stars in our Galaxy. The objects under study range from brown dwarfs that are sub-stellar in mass and have more in common with the Solar System giant planets than the stars, to very massive stars and clusters of stars, and also white dwarfs, which are the final evolutionary stage of 90% of all stars.

  • Galactic astronomy
    Galactic astronomy research at Gemini encompasses many aspects of galactic evolution including the role of stellar clusters and the interstellar medium in the evolution of the Galactic environment.  This research spans studies of the initial mass function, high mass clusters, stellar populations, infrared bubbles, molecular shocks, interstellar dust composition, and Galactic micro-quasar objects.

  • Extragalactic astronomy
    Extragalactic research at Gemini covers systems from the edge of the Galactic halo to high redshift. There is a strong contingent focusing on the nature of Active Galactic Nuclei (AGN). There is also extensive work on the evolution of galaxies and galaxy structures in environments ranging from the field, groups, and clusters over a wide range of look-back times.  Several of the staff are also studying the nature of extragalactic globular cluster systems and are using globular clusters to trace the mass distributions of the host galaxies.
