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…
Kepler-93: a testbed for detailed seismic modelling and orbital evolution of super-earths around solar-like stars
J. Bétrisey, C. Pezzotti, G. Buldgen +4
The advent of space-based photometry missions such as CoRoT, Kepler and TESS has sparkled the development of asteroseismology and exoplanetology. The advent of PLATO will further s…
Photo-astrometric distances, extinctions, and astrophysical parameters for Gaia EDR3 stars brighter than G=18.5
F. Anders, A. Khalatyan, A. B. A. Queiroz +23
We present a catalogue of 362 million stellar parameters, distances, and extinctions derived from Gaia's early third data release (EDR3) cross-matched with the photometric catalogu…
Asteroseismology of overmassive, undermassive, and potential past members of the open cluster NGC6791
K. Brogaard, T. Arentoft, J. Jessen-Hansen +1
We perform an asteroseismic investigation of giant stars in the field of NGC 6791 with previous indications of atypical evolution. The analysis makes use of observations from Keple…
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…
The K2 Galactic Archaeology Program Data Release 3: Age-abundance patterns in C1-C8 and C10-C18
Joel C. Zinn, Dennis Stello, Yvonne Elsworth +28
We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1-C8 and C10-C18. We provide asteroseismic radius and mass coefficients,…
