Acoustic vibrations – sound waves – are produced by radiation pressure inside stars. While physicists have long posited that young stars vibrate differently than older stars, a new study says it is the first to confirm these predications using concrete data from outer space. First author Konstanze Zwintz, a postdoctoral researcher at KU Leuven's Institute for Astronomy, and her colleagues studied the vibrations of 34 stars aged under 10 million years and sized between one and four times the mass of our sun. read more
