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

open access: yesThe 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.

Possible Evidence for the Presence of Volatiles on the Warm Super-Earth TOI-270 b

open access: yesThe Astronomical Journal
The search for atmospheres on rocky exoplanets is a crucial step in understanding the processes driving atmosphere formation, retention, and loss. Past studies have revealed the existence of planets interior to the radius valley with densities lower than

Precise Constraints on the Energy Budget of WASP-121 b from Its JWST NIRISS/SOSS Phase Curve

open access: yesThe Astronomical Journal
Ultra-hot Jupiters exhibit day-to-night temperature contrasts upwards of 1000 K due to competing effects of strong winds, short radiative timescales, magnetic drag, and H _2 dissociation/recombination. Spectroscopic phase curves provide critical insights

EUCLID : Dark Universe Probe and Microlensing planet Hunter

open access: yes, 2010
There is a remarkable synergy between requirements for Dark Energy probes by cosmic shear measurements and planet hunting by microlensing. Employing weak and strong gravitational lensing to trace and detect the distribution of matter on cosmic and ...

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

open access: yesThe 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

The Spin–Orbit Alignment of Eight Warm Gas Giant Systems

open access: yesThe 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
