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 …

We investigate the underlying distribution of orbital eccentricities for planets around early-to-
mid M dwarf host stars. We employ a sample of 163 planets around early-to mid-M dwarfs …

Compact nonresonant systems of sub-Jovian planets are the most common outcome of the
planet formation process. Despite exhibiting broad overall diversity, these planets also …

Super-Earths within the same close-in, compact planetary system tend to exhibit a striking
degree of uniformity in their radius, mass, and orbital spacing, and this" peas-in-a-pod" …

The high-multiplicity exoplanet systems are generally more tightly packed when compared
to the solar system. Such compact multiplanet systems are often susceptible to dynamical …

The Kepler spacecraft, whose single instrument was a 0.95 m diameter wide-field telescope,
operated in a heliocentric orbit for nearly a decade, returning a wealth of data that have …

It has been demonstrated that planets belonging to the same close-in, compact multiple-
planet system tend to exhibit a striking degree of uniformity in their sizes. A similar trend has …

The mutual inclination between planets orbiting the same star provides key information to
understand the formation and evolution of multiplanet systems. In this work, we investigate …

Although the architectures of compact multiple-planet systems are well characterized, there
has been little examination of their" outer edges," or the locations of their outermost planets …

Multiplanet systems face significant challenges to detection. For example, farther-orbiting
planets have a reduced signal-to-noise ratio in radial velocity detection methods, and small …
