The HAges Catalog: Stellar Ages For High Priority HWO Target Stars
Precise stellar ages (uncertainties âČ1 Gyr, or âŒ20% at solar age) are required to discern evolutionary trends in atmospheric biosignatures of terrestrial habitable zone exoplanets surveyed by the Habitable Worlds […]

Asteroseismic Modelling Of Main-sequence Solar-like Stars And Kepler Exoplanet Host Stars With The FICO Procedure I. Catalogue Of Fundamental Stellar Properties
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward and inverse techniques that enables […]

Prospects Of Detecting Rotational Flatness Of Exoplanets From Space-based Photometry
In the era of photometry with space-based telescopes, such as CHEOPS (CHaracterizing ExOPlanets Satellite), JWST (James Webb Space Telescope), PLATO (PLAnetary Transits and Oscillations of stars), and ARIEL (Atmospheric Remote-sensing […]

What Asteroseismology Can Do for Exoplanets
We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the […]
