Tiniest ‘starquakes’ detected in orange dwarf star

Groundbreaking discovery in astrophysics as researchers detect tiniest ‘starquakes’ in an orange dwarf star using the ESPRESSO spectrograph at the European Southern Observatory’s Very Large Telescope. This breakthrough marks the first confirmed detection of solar-like oscillations in a cool dwarf star with a surface temperature as low as 4,200 degrees Celsius, approximately 1,000 degrees cooler than the sun’s surface. The precision of these observations is unprecedented, with the detected oscillations reaching a peak amplitude of just 2.6 centimeters per second, highlighting the remarkable technological achievement of the research team.
