Stellar vibrations offer rare glimpse into red giant’s core, history
University of Hawaiʻi astronomers have revealed the history of a distant red giant star after analyzing its “starquakes,” which give scientists a glimpse beneath the star’s surface similarly to seismic waves on Earth.
UH: Unparalleled Bounty of Oscillating Red Giant Stars Detected
An unprecedented collection of pulsating giant red stars has been identified by astronomers at the University of Hawaiʻi Institute for Astronomy. Using observations from NASA’s Transiting Exoplanet Survey Satellite, the researchers detected the stars, whose rhythms arise from internal sound waves and provide the opening chords of a symphonic exploration of our galactic neighborhood.
