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…
Investigating the impact of Solar Fusion III reaction rates on helioseismic constraints and solar neutrino fluxes
T. Sandron, G. Buldgen, A. Noels +2
Nuclear reaction rates are crucial ingredients of solar and stellar models, they directly impact the duration of the life of stars and the energy they produce. In the solar case, t…
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…
A data-driven estimate of the protosolar helium mass fraction
G. Buldgen, M. Kunitomo, A. Noels +3
The protosolar helium mass-fraction is a key ingredient of solar, planetary models and enrichment laws. However, the assumed values often rely on simplified descriptions of the tra…
Eating planets makes you younger: The magnetic dynamo rejuvenation of GJ 504 by planetary engulfment
S. Bellotti, C. Pezzotti, G. Buldgen +3
With the discovery of a few thousand exoplanets, questions have been raised regarding star-planet interactions and whether the presence of a companion may affect stellar properties…
