Planet Hunters Talk

Mooned planet and planetary ring.

  • firejuggler by firejuggler

    So, we have found Light curevs wich could indicate planet with rings. But are we able to detect a planet with a moon orbiting it (especially a not tidally locked one)?
    Like, something ressembling our situation , a moon with a radius of a third to a fourth of its hosting planet? ( essentially on rocky planet)

    As far as I know, no moons around exoplanets have been confirmed yet, but it is surely only a matter of time. This wikipedia page lists five potential candidates

    Well that seems like progress, so just a matter of time. Here is another exomoon article although one from last year (and @firejuggler just search the internet for more):

    Abstract

    The co-planarity of solar system planets led Kant to suggest that they formed from an accretion disk, and the discovery of hundreds of such disks around young stars as well as hundreds of co-planar planetary systems by the Kepler satellite demonstrate that this formation mechanism is extremely widespread. Many moons in the solar system, such as the Galilean moons of Jupiter, also formed out of the accretion disks that coalesced into the giant planets. Here we report the discovery of an intermediate system, OGLE-2013-BLG-0723LB/Bb, composed of a Venus-mass planet orbiting a brown dwarf, which may be viewed either as a scaled-down version of a planet plus a star or as a scaled-up version of a moon plus a planet orbiting a star. The latter analogy can be further extended since they orbit in the potential of a larger, stellar body. For ice-rock companions formed in the outer parts of accretion disks, like Uranus and Callisto, the scaled masses and separations of the three types of systems are similar, leading us to suggest that the formation processes of companions within accretion disks around stars, brown dwarfs, and planets are similar.
