On the Possibility of Tidal Formation of Binary Planets Around Ordinary Stars
TL;DR: In this article, the formation of binary brown dwarfs was studied in the presence of a parent star and the potential for the capture of two planets, which leads to the creation of a binary brown dwarf in orbit about the parent star.

Abstract: The planet formation process and subsequent planet migration may lead to configurations resulting in strong dynamical interactions among the various planets Well-studied possible outcomes include collisions between planets, scattering events that eject one or more of the planets, and a collision of one or more of the planets with the parent star In this work we consider one other possibility that has seemingly been overlooked in the various scattering calculations presented in the literature: the tidal capture of two planets which leads to the formation of a binary planet (or binary brown dwarf) in orbit about the parent star We carry out extensive numerical simulations of such dynamical and tidal interactions to explore the parameter space for the formation of such binary planets We show that tidal formation of binary planets is possible for typical planet masses and distances from the host star The detection (or lack thereof) of planet-planet binaries can thus be used to constrain the properties of planetary systems, including their mutual spacing during formation, and the fraction of close planets in very eccentric orbits which are believed to form by a closely related process

TL;DR: In this article, the authors report on the discovery of stellar occultations, observed with Kepler, which recur periodically at 15.685 hr intervals, but which vary in depth from a maximum of 1.3% to a minimum that can be less than 0.2%.

The dynamical evolution of low-mass hydrogen-burning stars, brown dwarfs, and planetary-mass objects formed through disk fragmentation
TL;DR: In this paper, the authors study the dynamical evolution of very low-mass binaries, brown dwarfs, and planetary-mass objects (PMOs) via disk fragmentation, and predict observable properties of these objects, which can be used to distinguish between different formation scenarios.
Extrasolar Binary Planets II: Detectability by Transit Observations
TL;DR: In this paper, the authors discuss the detectability of gravitationally bound pairs of gas-giant planets in extrasolar planetary systems that are formed through orbital instability followed by planet?planet dynamical tides during their close encounters, based on the results of N-body simulations by Ochiai et al.
