Keplers Astounding Haul of Multiple-Planet Systems David Latham Harvard-Smithsonian Center for Astrophysics latham@cfa.harvard.edu
Kepler has found 1,235 planetary candidates: 827 singles 408 multiples in 170 planetary systems
Flatter than our solar system deg Degrees Can only see multiple transiting planets if all are edge-on Kepler systems are coplanar to ~1 degree
827 Single Planet Systems Detected Candidates from the first 120 days of Kepler data Planets smaller than Neptune are more common
408 candidates in 170 multiple systems Hot Jupiters are rare in flat systems Large planets stir things up, disrupt the flatness. Systems of small planets have more sedate histories
408 candidates in 170 multiple systems Many systems show gravitational interactions (transit time variations), which can be used to constrain planet masses and bulk densities. A way to distinguish rocky planets from water worlds
