The Densities of Planets in Multiple Stellar Systems [PDF]

, 2017
We analyze the effect of companion stars on the bulk density of 29 planets orbiting 15 stars in the Kepler field. These stars have at least one stellar companion within 2", and the planets have measured masses and radii, allowing an estimate of their ...

Planet–planet scattering alone cannot explain the free-floating planet population [PDF]

Monthly Notices of the Royal Astronomical Society: Letters, 2012
ABSTRACT Recent gravitational microlensing observations predict a vast population of free-floating giant planets that outnumbers main-sequence stars almost twofold. A frequently invoked mechanism for generating this population is a dynamical instability that incites planet–planet scattering and the ejection of one or more planets in ...
