Minimising magnetic activity effects in PLATO observations: insights from the Sun-as-a-star
Jérôme Bétrisey, Anne-Marie Broomhall, Sylvain N. Breton +4
Recent studies showed that magnetic activity effects in solar-type stars can substantially bias seismic inferences, particularly age estimates, regardless of modelling strategy or…
Luminaries in the Sky: The TESS LEGACY sample of bright stars. II. In-depth seismic characterisation of 32 naked-eye stars in the PLATO LOP fields
E. Panetier, G. T. Hookway, E. Corsaro +13
The NASA TESS mission is conducting a nearly full-sky survey, enabling the photometric characterisation of millions of stars. The forthcoming ESA PLATO mission will provide long-du…
Anti-Solar Differential Rotation May Have Revived Magnetic Braking in the Subgiant 31 Aquilae
Travis S. Metcalfe, Jennifer L. van Saders, Thomas R. Ayres +16
Recent observations have shown that sufficiently slow rotation disrupts the organization of large-scale magnetic field in older main-sequence stars, leading to weakened magnetic br…
Frequency separation ratios do not suppress magnetic activity effects in solar-like stars
Jérôme Bétrisey, Anne-Marie Broomhall, Sylvain N. Breton +3
Magnetic activity effects are typically neglected in asteroseismic modelling of solar-type stars, presuming that these effects can be accounted for in the parametrisation of the su…
