The Apparent Tidal Decay of WASP-4 b Can Be Explained by the Rømer Effect

Universe, 2023
Tidal orbital decay plays a vital role in the evolution of hot Jupiter systems. As of now, this has only been observationally confirmed for the WASP-12 system.

DYNAMIC EVOLUTION EXOPLANET SYSTEMS, MOVING IN ORBITAL RESONANCES WITH THE ACCOUNT OF SECULAR PERTURBATION FROM N BODIES

Odessa Astronomical Publications, 2017
Equations of exoplanet's motion connected with orbital Lindblad resonances with the account of secular terms caused by gravitational non-resonant perturbation are derived. Qualitative researches of orbital evolution modeling exoplanet systems are carried

Detecting Unresolved Binaries in TESS Data with Speckle Imaging [PDF]

, 2019
The Transiting Exoplanet Survey Satellite (TESS) is conducting a two-year wide-field survey searching for transiting exoplanets around nearby bright stars that will be ideal for follow-up characterization. To facilitate studies of planet compositions and

The Possible Evolution of an Exoplanet’s Atmosphere

Eos, 2021
Scientific sleuths explore data gathered trillions of kilometers away and put forth different, and often conflicting, ideas to reconstruct the gaseous envelope on a distant rocky exoplanet, GJ 1132 b.

Exoplanet status report: Observation, characterization and evolution of exoplanets and their host stars

Solar System Research, 2010
After the discovery of more than 400 planets beyond our Solar System, the characterization of exoplanets as well as their host stars can be considered as one of the fastest growing fields in space science during the past decade. The characterization of exoplanets can only be carried out in a well coordinated interdisciplinary way which connects ...

Spectral Evolution of an Earth-Like Planet [PDF]

, 2006
We have developed a characterization of the geological evolution of the Earths atmosphere and surface in order to model the observable spectra of an Earth-like planet through its geological history.

Evidence for Low-level Dynamical Excitation in Near-resonant Exoplanet Systems

The Astronomical Journal, 2023
The geometries of near-resonant planetary systems offer a relatively pristine window into the initial conditions of exoplanet systems. Given that near-resonant systems have likely experienced minimal dynamical disruptions, the spin–orbit orientations of ...

Effects of rotation and magnetic fields on the lithium abundance and asteroseismic properties of exoplanet-host stars

, 2010
Aims: The effects of rotation and magnetic fields on the surface abundances of solar-type stars are studied in order to investigate whether the reported difference in lithium content of exoplanet-host stars can be related to their rotational history ...
