Of the 18 known red giants in eclipsing binaries (RG/EBs), four do not show solar-like oscillations. These four also have the most signs of magnetic activity and tidal forces. A handful of the rest show suppressed oscillation modes with moderate levels of magnetism and tides. This paper uses Kepler light curves, high-resolution spectra, and stellar evolution modeling to demonstrate this trend and discuss the physical mechanisms responsible. Comments welcome.
