Asteroseismology of solar-like oscillators: emulating individual mode frequencies with a branching neural network
Owen J. Scutt, Guy R. Davies, Amalie Stokholm +6
Accurately measuring stellar ages and internal structures is challenging, but the inclusion of asteroseismic observables can substantially improve precision. However, the curse of…
Stellar Cruise Control: Weakened Magnetic Braking Leads to Sustained Rapid Rotation of Old Stars
Nicholas Saunders, Jennifer L. van Saders, Alexander J. Lyttle +8
Despite a growing sample of precisely measured stellar rotation periods and ages, the strength of magnetic braking and the degree of departure from standard (Skumanich-like) spindo…
The evolution of the Milky Way's thin disc radial metallicity gradient with K2 asteroseismic ages
Emma Willett, Andrea Miglio, J. Ted Mackereth +8
The radial metallicity distribution of the Milky Way's disc is an important observational constraint for models of the formation and evolution of our Galaxy. It informs our underst…
Systematics in Asteroseismic Modelling: Application of a Correlated Noise Model for Oscillation Frequencies
Tanda Li, Guy R. Davies, Martin Nielsen +2
The detailed modelling of stellar oscillations is a powerful approach to characterising stars. However, poor treatment of systematics in theoretical models leads to misinterpretati…
Asteroseismology of Scuti stars: emulating model grids using a neural network
Owen J. Scutt, Simon J. Murphy, Martin B. Nielsen +3
Young Scuti stars have proven to be valuable asteroseismic targets but obtaining robust uncertainties on their inferred properties is challenging. We aim to quantify the random…
Modelling stars with Gaussian Process Regression: Augmenting Stellar Model Grid
Tanda Li, Guy R. Davies, Alexander J. Lyttle +3
Grid-based modelling is widely used for estimating stellar parameters. However, stellar model grid is sparse because of the computational cost. This paper demonstrates an applicati…
