The Kepler Smear Campaign: Light curves for 102 very bright stars
Published 2019“…We describe the pipeline developed to extract and calibrate these light curves, and show that we attain photometric precision comparable to stars analyzed by the standard pipeline in the nominal Kepler mission. In this paper, aside from publishing the light curves of these stars, we focus on 66 red giants for which we detect solar-like oscillations, characterizing 33 of these in detail with spectroscopic chemical abundances and asteroseismic masses as benchmark stars. …”

Finding non-eclipsing binaries through pulsational phase modulation
Published 2015-01-01“…We present a method for finding binaries among pulsating stars that were observed by the Kepler Mission. We use entire four-year light curves to accurately measure the frequencies of the strongest pulsation modes, then track the pulsation phases at those frequencies in 10-d segments. …”

Mixed-mode Ensemble Asteroseismology of Low-luminosity Kepler Red Giants
Published 2023-01-01“…We present measurements of the dipole mode asymptotic period spacing (ΔΠ _1 ), the coupling factor between the p - and g -modes ( q ), the g -mode phase offset ( ϵ _g ), and the mixed-mode frequency rotational splitting ( δ ν _rot ) for 1074 low-luminosity red giants from the Kepler mission. Using oscillation mode frequencies extracted from each star, we apply Bayesian optimization to estimate ΔΠ _1 from the power spectrum of the stretched-period spectrum and to perform the subsequent forward modeling of the mixed-mode frequencies. …”
