Thermally Regulated Viscoelastic Tidal Migration of Eccentric Planets

The Astrophysical Journal Letters
A growing population of short-period Neptune-like planets has nonzero eccentricities and, in some cases, large stellar obliquities, suggestive of high-eccentricity migration. Modeling this evolution requires a prescription for tidal dissipation, which in

A Perfect Tidal Storm: HD 104067 Planetary Architecture Creating an Incandescent World

The Astronomical Journal
The discovery of planetary systems beyond the solar system has revealed a diversity of architectures, most of which differ significantly from our system.

Three-dimensional Orbital Architectures and Detectability of Adjacent Companions to Hot Jupiters

The Astrophysical Journal
The orbital properties of the (as yet) small population of hot Jupiters with nearby planetary companions provide valuable constraints on the past migration processes of these systems.

Evidence for a Peak at ∼0.3 in the Eccentricity Distribution of Typical Super-Jovian Exoplanets

The Astrophysical Journal Letters
In this study, we compute completeness-corrected occurrence rates of giant exoplanets as a function of mass, semimajor axis, and eccentricity, using the approximately uniform California Legacy Survey sample of radial velocity-discovered planets published

Free Floating or Merely Detached?

The Astrophysical Journal
Microlensing surveys suggest the presence of a surprisingly large population of free-floating planets, with a rate of about two Neptunes per star.

Transit timing analysis of the exoplanet TrES-5 b. Possible existence of the exoplanet TrES-5 c [PDF]

, 2018
In this work, we present transit timing variations detected for the exoplanet TrES-5b. To obtain the necessary amount of photometric data for this exoplanet, we have organized an international campaign to search for exoplanets based on the Transit Timing

A Comprehensive Analysis of Spitzer 4.5 μm Phase Curves of Hot Jupiters

The Astronomical Journal
Although exoplanetary science was not initially projected to be a substantial part of the Spitzer mission, its exoplanet observations set the stage for current and future surveys with JWST and Ariel.

A Direct Comparison between the Use of Double Gray and Multiwavelength Radiative Transfer in a General Circulation Model with and without Radiatively Active Clouds

The Astrophysical Journal
Inhomogeneous cloud formation and wavelength-dependent phenomena are expected to shape hot Jupiter atmospheres. We present a general circulation model with multiwavelength “picket fence” radiative transfer and radiatively active, temperature-dependent ...

Exoplanet Catalogue

An exoplanet is a planet that orbits another star other than the Sun; since 1988, more than 4,300 of them have been confirmed. This catalogue provides a visual way to visualise exoplanets in their solar systems, together with their habitable zones.
