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…
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
Ãngela 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…
