Detailed study of HD 219134: a benchmark K-dwarf with a compact planetary system
Jérôme Bétrisey, Camilla Pezzotti, Gaël Buldgen +4
Space missions such as CoRoT, Kepler, and TESS have transformed asteroseismology and its synergies with exoplanet science. We revisit the nearby K-dwarf HD 219134 to investigate th…
Physics-induced impact on the properties of Kepler/K2 solar analogs in the light of PLATO's requirements
Saniya Khan, Gaël Buldgen, Jérôme Bétrisey +2
Solar analogs are useful laboratories for tests of stellar structure and evolution, particularly in the context of the upcoming PLATO mission. Our study focuses on six seismic sola…
Asteroseismic modelling of main-sequence solar-like stars and Kepler exoplanet host stars with the FICO procedure I. Catalogue of fundamental stellar properties
Jérôme Bétrisey, Daniel R. Reese, Camilla Pezzotti +2
We present detailed asteroseismic modelling of 95 main-sequence solar-like stars and Kepler exoplanet host stars using the FICO procedure, a three-step method that combines forward…
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…
The stellar activity-rotation-age relationship under the lens of asteroseismology
C. Pezzotti, J. Bétrisey, G. Buldgen +6
In low-mass stars, the connection between magnetic activity, rotation period, and age provides key insights into the functioning of dynamos. Fully understanding the activity-rotati…
Asteroseismic modelling of Kepler Legacy stars including lithium depletion
