Synergies between Asteroseismology and Exoplanetary Science

TL;DR

Asteroseismology has become essential for characterizing exoplanet host stars and understanding planetary system architectures, enabling precise measurements of planetary and stellar properties and informing formation theories.

Contribution

This paper reviews current synergies between asteroseismology and exoplanet science and discusses future prospects for joint studies of exoplanets and their host stars.

Findings

Asteroseismology improves accuracy of planet radii and ages.

It helps measure orbital eccentricities and stellar obliquities.

Future work includes characterizing sub-Neptune planets and studying evolved star systems.

Abstract

Over the past decade asteroseismology has become a powerful method to systematically characterize host stars and dynamical architectures of exoplanet systems. In this contribution I review current key synergies between asteroseismology and exoplanetary science such as the precise determination of planet radii and ages, the measurement of orbital eccentricities, stellar obliquities and their impact on hot Jupiter formation theories, and the importance of asteroseismology on spectroscopic analyses of exoplanet hosts. I also give an outlook on future synergies such as the characterization of sub-Neptune-size planets orbiting solar-type stars, the study of planet populations orbiting evolved stars, and the determination of ages of intermediate-mass stars hosting directly imaged planets.
