“…A compact system of six transiting planets (Kepler-11, Lissauer et al 2011), five of which were confirmed by their mutual gravitational interactions exhibited through transit timing variations (TTVs), has also been reported. These systems provide important data for understanding the dynamics, formation and evolution of planetary systems (Koch et al 1996;Agol et al 2005;Holman & Murray 2005;Fabrycky 2009;Ragozzine & Holman 2010).…”

About one-third of the ∼1200 transiting planet candidates detected in the first four months of Kepler data are members of multiple candidate systems. There are 115 target stars with two candidate transiting planets, 45 with three, 8 with four, and one each with five and six. We characterize the dynamical properties of these candidate multi-planet systems. The distribution of observed period ratios shows that the vast majority of candidate pairs are neither in nor near low-order mean motion resonances. Nonetheless, there are small but statistically significant excesses of candidate pairs both in resonance and spaced slightly too far apart to be in resonance, particularly near the 2:1 resonance. We find that virtually all candidate systems are stable, as tested by numerical integrations that assume a nominal mass-radius relationship. Several considerations strongly suggest that the vast majority of these multi-candidate systems are true planetary systems. Using the observed multiplicity frequencies, we find that a single population of planetary systems that matches the higher multiplicities underpredicts the number of singly-transiting systems. We provide constraints on the true multiplicity and mutual inclination distribution of the multi-candidate systems, revealing a population of systems with multiple super-Earth-size and Neptune-size planets with low to moderate mutual inclinations.

“…A network was organized to search for transit of extrasolar planets (the "TEP" network). Moreover, space missions have been proposed to conduct long and continuous observations of large samples of stars to exploit the method of transits (Koch et al 1996;Borucki et al 1997). One of the main programs of the satellite COROT, that will be launched in 2001, is to achieve this goal (Schneider et al 1997).…”

Abstract. We compute the detection probability of satellites of extrasolar planets with the method of transits, under the assumption that the duration of the observations is at least as long as the planet orbital period. We separate the cases when the parent planet does and does not also transit over the star. The possible satellites are assumed to have orbital radii between the Roche limit and the Hill radius. We find that if a satellite is extended enough to produce a detectable drop in the stellar lightcurve, the probability to detect it when the planet also transits over the star is nearly unity. If the planet does not transit, the probability to detect a Jupiter-like or terrestrial satellite is modest, but it can be comparable to that of detecting a planet if the satellite orbital radius is large. If a satellite is not extended enough to produce a detectable drop in the stellar lightcurve during a transit, it might still be detected through the time shift of planetary transits resulting from the rotation of the planet around the barycenter of the planet-satellite system.
