In the past few years, significant advances have been made in understanding the
distributions of exoplanet populations and the architecture of planetary systems. We review …

We determine the orbital eccentricities of individual small Kepler planets, through a
combination of asteroseismology and transit light-curve analysis. We are able to constrain …

ABSTRACT π Men hosts a transiting super Earth (P≈ 6.27 d, m≈ 4.82 M⊕, R≈ 2.04 R⊕)
discovered by TESS and a cold Jupiter (P≈ 2093 d, m sin I≈ 10.02 M Jup, e≈ 0.64) …

The recent characterization of transiting close-in planets has revealed an intriguing
population of sub-Neptunes with highly tilted and even polar orbits relative to their host star's …

Transiting exoplanets in multi-planet systems have non-Keplerian orbits which can cause
the times and durations of transits to vary. The theory and observations of transit timing …

Early analyses of exoplanet statistics from the Kepler mission revealed that a model
population of multiplanet systems with low mutual inclinations (∼ 1–2) adequately describes …

Context. Measuring the geometry of multi-planet extrasolar systems can provide insight into
their dynamical history and the processes of planetary formation. These types of …

We study how close-in systems such as those detected by Kepler are affected by the
dynamics of bodies in the outer system. We consider two scenarios: outer systems of giant …

Because of the diversity of stellar masses and orbital sizes of binary systems and the
complex interaction between star–star, star–planet, and planet–planet, it has been difficult to …

We present a detailed characterization of the Kepler-411 system (KOI 1781). This system
was previously known to host two transiting planets: one with a period of 3 days (R= 2.4 R⊕; …
