Characterizing six seismic solar analogs observed by Kepler, K2, and HERMES
R. A. García, 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…
Asteroseismic calibration of the Rossby number and its connection to the stellar dynamo and fundamental properties
Alfio Bonanno, Enrico Corsaro, Travis S. Metcalfe +3
The stellar Rossby number, a dimensionless parameter quantifying the influence of Coriolis forces on convective motions, plays a pivotal role in understanding magnetic stellar evol…
Rotation of young solar-type stars as seen by Gaia and K2
Sylvain N. Breton, Elisa Distefano, Alessandro C. Lanzafame +1
Accurate surface rotation measurements are crucial to estimate stellar ages and improve our understanding of stellar rotational evolution. Comparisons of datasets obtained from dif…
Influence of the magnetic activity cycle on mean density and acoustic radius inversions
Jérôme Bétrisey, Daniel R. Reese, Sylvain N. Breton +4
Asteroseismic modelling is crucial for upcoming missions like PLATO, CubeSpec, and Roman. Despite significant progress, discrepancies between observations and theoretical predictio…
Signature of spin-down stalling in stellar magnetic activity. The case of the open cluster NGC 6811
Ângela R. G. Santos, Diego Godoy-Rivera, Savita Mathur +3
Stellar rotation and magnetic activity have a complex evolution that reveals multiple regimes. One of the related transitions that is seen in the rotation distribution for main-seq…
Magnetic activity evolution of solar-like stars: II. -Ro evolution of Kepler main-sequence targets
Savita Mathur, Angela R. G. Santos, Zachary R. Claytor +16
There is now a large sample of stars observed by the Kepler satellite with measured rotation periods and photometric activity index . We use this data, in conjunction w…
Solar p-modes excitation rate along the magnetic activity cycle
E. Panetier, S. N. Breton, R. A. García +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…
Seismic differences between solar magnetic cycles 23 and 24 for low-degree modes
Rafael A. Garcia, Sylvain N. Breton, David Salabert +4
Solar magnetic activity follows regular cycles of about 11 years with an inversion of polarity in the poles every 22 years. This changing surface magnetism impacts the properties o…
TESS asteroseismology of Hydri: a subgiant with a born-again dynamo
Travis S. Metcalfe, Jennifer L. van Saders, Daniel Huber +12
The solar-type subgiant Hyi has long been studied as an old analog of the Sun. Although the rotation period has never been measured directly, it was estimated to be near 27 day…
Imprint of the magnetic activity cycle on solar asteroseismic characterisation based on 26 years of GOLF and BiSON data
Jérôme Bétrisey, Martin Farnir, Sylvain N. Breton +4
Building on the success of previous missions, asteroseismic modelling will play a key role in future space-based missions, such as PLATO, CubeSpec, and Roman. Despite remarkable ac…
Measuring stellar surface rotation and activity with the PLATO mission -- I. Strategy and application to simulated light curves
S. N. Breton, A. F Lanza, S. Messina +20
The Planetary Transits and Oscillations of stars mission (PLATO) will allow us to measure surface rotation and monitor photometric activity of tens of thousands of main sequence so…
The PLATO Mission
Heike Rauer, Conny Aerts, Juan Cabrera +842
PLATO (PLAnetary Transits and Oscillations of stars) is ESA's M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large numb…
Kepler main-sequence solar-like stars: surface rotation and magnetic-activity evolution
A. R. G. Santos, D. Godoy-Rivera, A. J. Finley +4
While the mission's primary goal was focused on exoplanet detection and characterization, Kepler made and continues to make extraordinary advances in stellar physics. Stellar rotat…
