Kepler-discovered Multiple-planet Systems near Period Ratios Suggestive of Mean-motion Resonances Are Young

The Astronomical Journal
Before the launch of the Kepler Space Telescope, models of low-mass planet formation predicted that convergent type I migration would often produce systems of low-mass planets in low-order mean-motion resonances.

The Spin–Orbit Alignment of Eight Warm Gas Giant Systems

The Astronomical Journal
Essential information about the formation and evolution of planetary systems can be found in their architectures—in particular, in stellar obliquity ( ψ )—as they serve as a signature of their dynamical evolution. Here we present ESPRESSO observations of

The K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet

The Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due

Keck and Hubble Observations Show that MOA-2008-BLG-379Lb is a Super-Jupiter Orbiting an M Dwarf

The Astronomical Journal
We present high angular resolution imaging that detects the MOA-2008-BLG-379L exoplanet host star using Keck adaptive optics and the Hubble Space Telescope.
