Helium abundance in a sample of cool stars: measurements from asteroseismology
Kuldeep Verma, Keyuri Raodeo, Sarbani Basu +5
The structural stratification of a solar-type main sequence star primarily depends on its mass and chemical composition. The surface heavy element abundances of the solar-type star…
Stellar ages, masses and radii from asteroseismic modeling are robust to systematic errors in spectroscopy
Earl P. Bellinger, Saskia Hekker, George C. Angelou +2
The search for twins of the Sun and Earth relies on accurate characterization of stellar and exoplanetary parameters: i.e., ages, masses, and radii. In the modern era of asteroseis…
Explaining Deviations from the Scaling Relationship of the Large Frequency Separation
Joel Ong, Sarbani Basu
Asteroseismic large frequency separations possess great diagnostic value. However, their expressions as scaling relations are predicated on homology arguments which may not hold in…
Improved calibration of the radii of cool stars based on 3D simulations of convection: implications for the solar model
F. Spada, P. Demarque, S. Basu +1
Main sequence, solar-like stars (M < 1.5 Msun) have outer convective envelopes that are sufficiently thick to affect significantly their overall structure. The radii of these stars…
The robustness of asteroseismic estimates of global stellar parameters to surface term corrections
Sarbani Basu, Archer Kinnane
Oscillation frequencies of even the best stellar models differ from those of the stars they represent, and the difference is predominantly a function of frequency. This difference…
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…
