Exploring Exoplanet Dynamics with JWST: Tides, Rotation, Rings, and Moons

TL;DR

This paper discusses how JWST can significantly advance our understanding of exoplanet dynamics by measuring phenomena like tides, rotation, rings, and moons, which are currently difficult to observe.

Contribution

It introduces the potential of JWST to observe and analyze complex dynamical features of exoplanets that were previously inaccessible.

Findings

JWST can detect tidal distortions and inflation in exoplanets.

JWST can observe planetary rings and moons.

Enhanced measurement precision will improve exoplanet characterization.

Abstract

Although nearly 6,000 exoplanets are currently known, in most cases our knowledge is limited to a handful of the planet's orbital characteristics and bulk properties such as radius and mass. The James Webb Space Telescope (JWST) can expand our knowledge not only by probing exoplanet atmospheres, but also by measuring additional orbital and physical properties of exoplanets, thanks to its superior light-gathering power and measurement precision. Here, we describe the potential of JWST to unveil dynamical phenomena that were previously beyond our reach, such as tidal distortion and inflation, rotational flattening, planetary rings, and moons.
