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…
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…
Multi-waveband detection of quasi-periodic pulsations in a stellar flare on EK Draconis observed by XMM-Newton
A. -M. Broomhall, A. E. L. Thomas, C. E. Pugh +2
Context. Quasi-periodic pulsations (QPPs) are time variations in the energy emission during a flare that are observed on both the Sun and other stars and thus have the potential to…
Asteroseismic constraints on active latitudes of solar-type stars: HD173701 has active bands at higher latitudes than the Sun
Alexandra E. L. Thomas, William J. Chaplin, Guy R. Davies +6
We present a new method for determining the location of active bands of latitude on solar-type stars, which uses stellar-cycle-induced frequency shifts of detectable solar-like osc…
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…
Galactic Archaeology with TESS: Prospects for Testing the Star Formation History in the Solar Neighbourhood
Alexandra Thomas, Emma Stevenson, Fabian W. R. Gittins +5
A period of quenching between the formation of the thick and thin disks of the Milky Way has been recently proposed to explain the observed age-[α/Fe] distribution of stars in the…
