Origins of Compact Mean-motion Resonances: Evidence for Long-range Migration and the Case of Kepler-36

The Astrophysical Journal
The observed census of resonant extrasolar planets spans a tantalizing display of orbital architectures, ranging from familiar 2:1 and 3:2 mean-motion commensurabilities to nearly coorbital configurations characterized by period ratios close to unity ...

The influence of hypothetical exomoons on planetary thermal phase curves

Astronomy & Astrophysics
Context. More than 200 moons exist in our Solar System, yet no exomoon has been confirmed to date. While the innermost two planets of the Solar System lack natural satellites and most studies favour the existence of exomoons around long-period planets ...

The Wanderer: Charting WASP-77A b’s Formation and Migration Using a System-wide Inventory of Carbon and Oxygen Abundances

The Astrophysical Journal
The elemental and isotopic abundances of volatiles like carbon, oxygen, and nitrogen may trace a planet’s formation location relative to H _2 O, CO _2 , CO, NH _3 , and N _2 “snowlines,” or the distance from the star at which these volatile elements ...

EUCLID : Dark Universe Probe and Microlensing planet Hunter

, 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 OATMEAL Survey. II. The 3D Spin–Orbit Obliquity of an Eccentric Transiting Brown Dwarf in the Ruprecht 147 Open Cluster

The Astronomical Journal
We present a new analysis of the CWW 89 system as part of the Orbital Architectures of Transiting Massive Exoplanets And Low-mass stars (OATMEAL) survey. The CWW 89 system is a member of the 2.8 Gyr old Ruprecht 147 (NGC 6774) cluster and consists of two

An Analytical Model for the Eccentricity Cascade: Hot Jupiter Formation via S-type Instability

The Astrophysical Journal
A widely explored pathway for hot Jupiter (HJ) formation is high-eccentricity migration driven by von Zeipel–Lidov–Kozai cycles induced by an exterior companion.
