![]() ![]() The video effects and transitions are fast and easy to manage. Universe is an exceptional value for video editors of any skill level. ![]() We discuss these results in the context of various asteroseismic observables, including the population of red giants that exhibit dipole modes with unusually small amplitudes. The lens flares of Knoll Light Factory EZ rendered instantaneously, an incredibly different experience from the early days of the effect’s predecessor. For stars with 150 < nu max < 200 microHz, the average amplitudes are one to two times smaller. We find that for stars whose frequency of maximum power nu max < 100 microHz, the parent amplitudes are five to ten times smaller, on average, than in the linear calculations. By solving the amplitude equations that describe the mode dynamics, we determine the nonlinear saturation energy of the modes in our networks. We construct large networks of nonlinearly coupled modes consisting of stochastically driven parent modes coupled to resonant secondary modes (daughters, granddaughters, etc.). We find that modes near the peak of the observed power spectrum are unstable to three-wave interactions over a broad range of stellar mass and evolutionary state. Here we analyze the stability of mixed modes in red giants to nonlinear, resonant three-wave interactions. Thus, the linear approximation may not always be valid. No red dwarf yet born in this universe has ever come close to dying, as far as we know, as the universe is not old enough for any red dwarf to complete its life. ![]() However, Kepler observations show that the oscillation amplitudes increase dramatically as stars ascend the red giant branch. Asteroseismic studies of red giants generally assume that the oscillation modes can be treated as linear perturbations to the background star. ![]()
