The rotation of a star and the revolutions of its planets are not necessarily aligned. This
article reviews the measurement techniques, key findings, and theoretical interpretations …

The basic geometry of the Solar System—the shapes, spacings, and orientations of the
planetary orbits—has long been a subject of fascination as well as inspiration for planet …

The distribution of planet sizes encodes details of planet formation and evolution. We
present the most precise planet size distribution to date based on Gaia parallaxes, Kepler …

Thousands of exoplanets have now been discovered with a huge range of masses, sizes
and orbits: from rocky Earth-like planets to large gas giants grazing the surface of their host …

Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an
ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and …

The original Kepler mission achieved high photometric precision thanks to ultrastable
pointing enabled by use of four reaction wheels. The loss of two of these reaction wheels …

We carried out a Bayesian homogeneous determination of the orbital parameters of 231
transiting giant planets (TGPs) that are alone or have distant companions; we employed …

Exoplanet discoveries of recent years have provided a great deal of new data for studying
the bulk compositions of giant planets. Here we identify 47 transiting giant planets (20 M⊕< …

The determination of exoplanet properties and occurrence rates using Kepler data critically
depends on our knowledge of the fundamental properties (such as temperature, radius, and …

Kepler provides light curves of 156,000 stars with unprecedented precision. However, the
raw data as they come from the spacecraft contain significant systematic and stochastic …
