starquakes
Neutron star tremors
Starquakes are seismic vibrations in neutron stars—the ultra-dense remnants of collapsed massive stars.
Like earthquakes on Earth, starquakes involve sudden shifts in the star's crust, releasing enormous energy.
These events can cause observable changes in the star's rotation and emit detectable radiation: The magnetar's starquake was detected by orbiting telescopes.
