Age Determination of Galaxy Merger Remnant Stars using Asteroseismology
Camilla C. Borre, Víctor Aguirre Børsen-Koch, Amina Helmi +12
The Milky Way was shaped by the mergers with several galaxies in the past. We search for remnant stars that were born in these foreign galaxies and assess their ages in an effort t…
Constraining the Rotation Profile in a Low-Luminosity Subgiant with a Surface Rotation Measurement
T. Wilson, A. R. Casey, I. Mandel +3
Rotationally-induced mode splitting frequencies of low-luminosity subgiants suggest that angular momentum transport mechanisms are 1-2 orders of magnitude more efficient in these s…
The BAyesian STellar Algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology
V. Aguirre Børsen-Koch, J. L. Rørsted, A. B. Justesen +16
We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source code written in {\tt Python} to determine stellar properties based on a set of astrophysic…
The K2 Galactic Archaeology Program Data Release 3: Age-abundance patterns in C1-C8 and C10-C18
Joel C. Zinn, Dennis Stello, Yvonne Elsworth +28
We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1-C8 and C10-C18. We provide asteroseismic radius and mass coefficients,…
Hierarchically modelling Kepler dwarfs and subgiants to improve inference of stellar properties with asteroseismology
Alexander J. Lyttle, Guy R. Davies, Tanda Li +9
With recent advances in modelling stars using high-precision asteroseismology, the systematic effects associated with our assumptions of stellar helium abundance () and the mixi…
Weakened magnetic braking supported by asteroseismic rotation rates of Kepler dwarfs
Oliver J. Hall, Guy R. Davies, Jennifer van Saders +9
Studies using asteroseismic ages and rotation rates from star-spot rotation have indicated that standard age-rotation relations may break down roughly half-way through the main seq…
Lifetimes and Rotation within the Solar Mean Magnetic Field
Eddie Ross, William J. Chaplin, Steven J. Hale +4
We have used very high-cadence (sub-minute) observations of the solar mean magnetic field (SMMF) from the Birmingham Solar Oscillations Network (BiSON) to investigate the morpholog…
Impact of magnetic activity on inferred stellar properties of main sequence Sun-like stars
Alexandra E. L. Thomas, William J. Chaplin, Sarbani Basu +3
The oscillation frequencies observed in Sun-like stars are susceptible to being shifted by magnetic activity effects. The measured shifts depend on a complex relationship involving…
