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 +14
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…
Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. GarcÃa, S. Mathur, G. T. Hookway +31
Solar analogs, stars that closely match the fundamental properties of the Sun, provide key benchmarks for testing stellar structure and evolution across different ages and activity…
Dynamical mass of a solar-like oscillator at the main-sequence turnoff from Gaia astrometry & ground-based spectroscopy
P. G. Beck, T. Masseron, K. Pavlovski +11
Asteroseismology is widely used for precise determining of masses of solar-like oscillating stars by performing individual-frequency modeling or applying homological scaling relati…
Is convective turbulence the only exciting mechanism of global p modes in the Sun?
E. Panetier, R. A. GarcÃa, S. N. Breton +2
In solar-like oscillators, acoustic waves are excited by turbulent motion in the convective envelope and propagate inward, generating a variety of standing pressure modes. When com…
Solar p-modes excitation rate along the magnetic activity cycle
E. Panetier, S. N. Breton, R. A. GarcÃa +2
Magnetic cycles of solar-like stars influence their internal physics. Thus, the frequency, amplitude, excitation rate, and damping of the acoustic oscillation modes (p-modes) vary…
