Conclusions

  • Upper limit placed on moon masses in extrasolar planetary systems
  • .
  • HD209458b unlikely to have any prograde primordial satellites over 1e-6 Earth masses (or ~100km diameter)
  • .
  • We can place no limits on satellite masses for planets beyond ~.4AU from their central star
  • .
  • A discovery could reveal information about planet's tidal Q


  • Thanks for sticking around until Saturday afternoon
