Glitch analysis and asteroseismic modelling of subgiant Herculis: confirming and interpreting the peak as the helium glitch
Advik Gupta, Kuldeep Verma, Hans Kjeldsen +7
The measurements of pressure-mode and mixed-mode oscillation frequencies in subgiant stars offer a unique opportunity to probe their internal structures -- from the surface to the…

Pushing the boundaries of asteroseismic individual frequency modelling: unveiling two evolved very-low metallicity red giants
Jens R. Larsen, Jakob L. Rørsted, Victor Aguirre Børsen-Koch +21
Metal-poor stars are key to understanding the first stellar generation in the Galaxy. Asteroseismic characterisation of red giants has traditionally relied on global seismic parame…

A link between rocky exoplanet composition and stellar age
Angharad Weeks, Vincent Van Eylen, Daniel Huber +7
Interior compositions are key for our understanding of Earth-like exoplanets. The composition of the core can influence the presence of a magnetic dynamo and the strength of gravit…
