Modeling of two CoRoT solar analogues constrained by seismic and spectroscopic analysis
Baudin, F.; Samadi, R.; Morel, T. +8 more
Solar analogues are important stars to study for understanding the properties of the Sun. Combined with seismic and spectroscopic analysis, evolutionary modelling becomes a powerful method to characterize stellar intrinsic parameters, such as mass, radius, metallicity and age. However, these characteristics, relevant for other aspects of astrophys…
Fundamental properties of stars from Kepler and Gaia data: parallax offset and revised scaling relations
Örtel, S.; Yıldız, M.
Data from the space missions Gaia, Kepler, CoRoT and TESS, make it possible to compare parallax and asteroseismic distances. From the ratio of two densities ρsca/ρπ, we obtain an empirical relation fΔν between the asteroseismic large frequency separation and mean density, which is important for more accurate stella…
