Age dating of an early Milky Way merger via asteroseismology of the naked-eye star Indi

William J. Chaplin, Aldo M. Serenelli, Andrea Miglio +81

Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies. While these accreted stellar populations can be forensically identified as kinematic…

TOI-257b (HD 19916b): A Warm sub-Saturn Orbiting an Evolved F-type Star

Brett C. Addison, Duncan J. Wright, Belinda A. Nicholson +91

We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS…

KIC 2568888: To be or not to be a binary

N. Themeßl, S. Hekker, A. Mints +4

In cases where both components of a binary system show oscillations, asteroseismology has been proposed as a method to identify the system. For KIC 2568888, observed with ,…

Surface effects on the red giant branch

W. H. Ball, N. Themeßl, S. Hekker

Individual mode frequencies have been detected in thousands of individual solar-like oscillators on the red giant branch (RGB). Fitting stellar models to these mode frequencies, ho…

Oscillating red giants in eclipsing binary systems: empirical reference value for asteroseismic scaling relation

N. Themeßl, S. Hekker, J. Southworth +10

The internal structures and properties of oscillating red-giant stars can be accurately inferred through their global oscillation modes (asteroseismology). Based on 1460 days of Ke…

Automated asteroseismic peak detections

Andrés García Saravia Ortiz de Montellano, Saskia Hekker, Nathalie Themeßl

Space observatories such as have provided data that can potentially revolutionise our understanding of stars. Through detailed asteroseismic analyses we are capab…
