Stream Red Giant Star 74 Draconis Pulsation by NASA

Listen to the rhythms of the pulsating red giant star called 74 Draconis based on brightness measurements from NASA’s Transiting Exoplanet Survey Satellite. Just below the surfaces of these stars, hot gas rises, cools, and then sinks, where it heats up again, much like a pan of boiling water on a hot stove. This motion produces waves of changing pressure – sound waves. The interaction of these waves results in orderly motion called standing waves that create measurable changes in the star’s brightness. Larger stars produce longer oscillations and thus have deeper tones. To produce audible tones, astronomers multiplied its oscillation frequency by 3 million times.
