Light signal of stars turned into sound

Dear followers,

Scientists from Vanderbilt University (Nashville, TN), Fisk University (Nashville, TN), University of California (Berkeley, California), Lehigh University (Bethlehem, Pennsylvania) have turned light signals from distant stars into sound. Acoustic oscillations and transits don't interfere with each other: sound waves cause the brightness of Sun-like stars to vary on time scales of 5–15 minutes, whereas planetary transits last for hours.
