Higher metal abundances do not solve the solar problem
G. Buldgen, P. Eggenberger, A. Noels +4
Context. The Sun acts as a cornerstone of stellar physics. Thanks to spectroscopic, helioseismic and neutrino flux observations, we can use the Sun as a laboratory of fundamental p…
Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
S. Sulis, M. Lendl, H. Cegla +83
Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…
Backtracing the internal rotation history of the Cep star HD 129929
Sébastien Salmon, Facundo Moyano, Patrick Eggenberger +2
HD 129929 is a slowly-rotating Cephei pulsator with a rich spectrum of detected oscillations, including two rotational multiplets. The asteroseismic interpretation revealed the…
Thorough characterisation of the 16 Cygni system. Part II. Seismic inversions of the internal structure
G. Buldgen, M. Farnir, P. Eggenberger +5
The advent of space-based photometry observations provided high-quality asteroseismic data for a large number of stars. These observations enabled the adaptation of advanced techni…
Asteroseismology of Cephei stars: The stellar inferences tested in hare and hound exercises
Sébastien Salmon, Patrick Eggenberger, Josefina Montalbán +5
The Cephei pulsators are massive main-sequence stars, presenting low radial-order modes. These modes probe in particular the chemical gradient at the edge of the convective cor…
Asteroseismology of evolved stars to constrain the internal transport of angular momentum. IV. Internal rotation of Kepler 56 from an MCMC analysis of the rotational splittings
L. Fellay, G. Buldgen, P. Eggenberger +4
The observations of global stellar oscillations of post main-sequence stars by space-based photometry missions allowed to directly determine their internal rotation. These constrai…
