Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
Asteroseismology of the Multiplanet System K2-93
Mikkel N. Lund, Emil Knudstrup, Victor Silva Aguirre +14
We revisit the analysis of the bright multiplanet system K2-93, discovered with data taken by the K2 mission. This system contains five identified planets ranging in size from sub-…
Asteroseismic ages of red-giant stars from grid-based modelling: the impact of systematics in effective temperature or metallicity
Saskia Hekker, Sarbani Basu
An increasingly popular method to determine stellar ages of red-giant stars for the purpose of Galactic archaeology is asteroseismic grid-based modelling (GBM). In asteroseismic GB…
Testing stellar evolution with asteroseismic inversions of a main sequence star harboring a small convective core
Earl P. Bellinger, Sarbani Basu, Saskia Hekker +1
The goal of stellar evolution theory is to predict the structure of stars throughout their lifetimes. Usually, these predictions can be assessed only indirectly, for example by com…
Structural and Evolutionary Diagnostics from Asteroseismic Phase Functions
Joel Ong, Sarbani Basu
In the asymptotic parameterisation of mode frequencies, the phase function completely specifies the detailed structure of the frequency eigenvalues. In practice, however, th…
Sensitivity of low-degree solar p modes to active and ephemeral regions: frequency shifts back to the Maunder Minimum
William J. Chaplin, Rachel Howe, Sarbani Basu +7
We explore the sensitivity of the frequencies of low-degree solar p-modes to near-surface magnetic flux on different spatial scales and strengths, specifically to active regions wi…
