Formation and Detection of Habitable Exomoons

Presenter: Rene Heller, McMaster University
When: April 14, 2015 3PM PDT

While about 4,000 planets and planet candidates have been found outside the solar system, no moon around an exoplanet (or “exomoon”) has been found so far. New simulations indicate that moons similar in mass to planet Mars exist around the biggest planets outside the solar system, and recent advances in exomoon searching methods suggest that these large moons are observable with current and near-future technology. The detection of these moons would not only provide extremely valuable insights into planet formation and evolution, but could also reveal a recently predicted class of Mars-mass moons in the stellar habitable zones. These moons would be several times as massive as Ganymede, the most massive moon in the solar system, and they could be abundant extrasolar habitats with odd day-night cycles.
