High-precision abundances of elements in solar-type stars. Evidence of two distinct sequences in abundance-age relations
P. E. Nissen, J. Christensen-Dalsgaard, J. R. Mosumgaard +3
HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr…
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…
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…
The subgiant HR 7322 as an asteroseismic benchmark star
Amalie Stokholm, Poul Erik Nissen, Victor Silva Aguirre +5
We present an in-depth analysis of the bright subgiant HR 7322 (KIC 10005473) using Kepler short-cadence photometry, optical interferometry from CHARA, high-resolution spectra from…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
Helium abundance in a sample of cool stars: measurements from asteroseismology
Kuldeep Verma, Keyuri Raodeo, Sarbani Basu +5
The structural stratification of a solar-type main sequence star primarily depends on its mass and chemical composition. The surface heavy element abundances of the solar-type star…
