TL;DR: In this paper, a sample of 93 Kepler eclipsing binary stars with g-mode pulsating components and identified clear gmode period-spacing patterns in the frequency spectra of seven of these systems.

TL;DR: In this paper , a catalog of intermediate-mass stars in the Transiting Exoplanet Survey Satellite (TESS) southern continuous viewing zone (CVZ) to reveal period-spacing patterns caused by gravity modes for use in future asteroseismic modeling is presented.

TL;DR: In this paper, the authors present a case study of the eclipsing binary KIC9850387, identified as the most promising candidate for future evolutionary and asteroseismic modelling.

TL;DR: In this article , a hierarchical triple system with clear eclipse timing and depth variations was discovered by the Kepler satellite during its original mission, which was noted for the large amplitude of its eclipse timing variations (over 4 hours), and the detection of clear solar-like oscillations of the red-giant component, including p- modes of degree up to l = 3 and mixed l = 1 modes.
