Predicting Granulation "Flicker" and Radial Velocity "Jitter" from Spectroscopic Observables
Jamie Tayar, Keivan G. Stassun, Enrico Corsaro
Surface granulation can be predicted with the mass, metallicity, and frequency of maximum power of a star. Using the orders-of-magnitude larger APOGEE-Kepler sample, we recalibrate…
FliPer: A global measure of power density to estimate surface gravities of main-sequence Solar-like stars and red giants
L. Bugnet, R. A. García, G. R. Davies +4
Asteroseismology provides global stellar parameters such as masses, radii or surface gravities using the mean global seismic parameters as well as the effective temperature for tho…
The rotational shear layer inside the early red-giant star KIC 4448777
M. P. Di Mauro, R. Ventura, E. Corsaro +1
We present the asteroseismic study of the early red-giant star KIC 4448777, complementing and integrating a previous work (Di Mauro et al. 2016), aimed at characterizing the dynami…
Oscillating red giants in eclipsing binary systems: empirical reference value for asteroseismic scaling relation
N. Themeßl, S. Hekker, J. Southworth +10
The internal structures and properties of oscillating red-giant stars can be accurately inferred through their global oscillation modes (asteroseismology). Based on 1460 days of Ke…
The Second APOKASC Catalog: The Empirical Approach
Marc H. Pinsonneault, Yvonne P. Elsworth, Jamie Tayar +33
We present a catalog of stellar properties for a large sample of 6676 evolved stars with APOGEE spectroscopic parameters and \textit{Kepler} asteroseismic data analyzed using five…
Asteroseismology of KIC 7107778: a binary comprising almost identical subgiants
Yaguang Li, Timothy R. Bedding, Tanda Li +5
We analyze an asteroseismic binary system: KIC 7107778, a non-eclipsing, unresolved target, with solar-like oscillations in both components. We used \emph{Kepler} short cadence tim…
