"The “music” of starquakes – enormous vibrations caused by bursting bubbles of
gas that ripple throughout the bodies of many stars – can reveal far more
information about the stars’ histories and inner workings than scientists
thought.
In new research published in
Nature, we analysed the frequency signatures of
starquakes across a broad range of giant stars in the M67 star cluster, almost
3,000 light years from Earth.
Using observations from the Kepler space telescope’s K2 mission, we had a rare
opportunity to track the evolution of stars during most of their journey
through the giant phase of the stellar life cycle.
In doing so, we discovered that these stars get stuck “playing the same part of
their tune” once their turbulent outer layer reaches a sensitive region deep
inside.
This discovery reveals a new way to understand the history of stars – and of
the entire galaxy."
