Abstract:
We present a study of the relative sizes of planets within the
multiple-candidate systems discovered with the Kepler mission
(Burke+, 2014, J/ApJS/210/29). We have compared the size of each
planet to the size of every other planet within a given planetary
system after correcting the sample for detection and geometric biases.
We find that for planet pairs for which one or both objects are
approximately Neptune-sized or larger, the larger planet is most often
the planet with the longer period. No such size-location correlation
is seen for pairs of planets when both planets are smaller than
Neptune. Specifically, if at least one planet in a planet pair has a
radius of ≳3R⊕, 68%±6% of the planet pairs have the inner
planet smaller than the outer planet, while no preferred sequential
ordering of the planets is observed if both planets in a pair are
smaller than ≲3R⊕.

Note (1): Planets are labeled with roman numerals (I, II, III, IV, V, VI)
in the order of increasing orbital period. These do not necessarily
correspond to KOI fraction numbers (e.g.,.01,.02,...) nor do they
correspond to the confirmed planet letters (e.g., Kepler-11b,
Kepler-11c,...).
