‘Starquakes’ could Explain Mystery Signals

Fast radio bursts from distant neutron stars resemble earthquakes rather than solar flares. Fast radio bursts, or FRBs, are an astronomical mystery, with their exact cause and origins still unconfirmed. These intense bursts of radio energy are invisible to the human eye, but show up brightly on radio telescopes. Previous studies have noted broad similarities between the energy distribution of repeat FRBs, and that of earthquakes and solar flares...

Starquakes Reveal Surprises about Birth of Stars in our Galaxy

The spins of about 70% of the red giant stars observed in the clusters were strongly aligned in a study by researchers including Dr Dennis Stello.

A study of the internal sound waves created by starquakes, which make stars ring like a bell, has provided unprecedented insights into conditions in the turbulent gas clouds where stars were born 8 billion years ago. Astronomers used this asteroseismology approach to work out the orientation of the angle of spin of 48 stars in our galaxy, the Milky Way. The spins of about 70% of the red giant stars observed in the clusters were strongly aligned in a study by researchers including Dr Dennis Stello...
