(redirected from Starquakes)


A violent rift in the dense surface of a magnetar that has been warped by its own intense magnetic field.

It is the first planet that has been identified by the mission in which a distant planet's "starquakes" could be measured - allowing scientists to learn even more about its character.
However, sometimes the neutron stars will glitch due to starquakes, causing them to wobble and either speed up or slow down in their spinning.
Already, K2 has found 270 planet candidates and 30 confirmed planets, and it's also observed open star clusters, measured starquakes and other stellar rumblings, and searched for supernovae.
The starquakes, reported by the space agency last night, are allowing astronomers to learn about the stars' age, size and evolution.
Washington, Oct 27 (ANI): NASA's Keplar spacecraft has discovered stellar oscillations, or 'starquakes,' that could provide new insights about the size, age and evolution of stars.
Astronomers developed a technique for predicting starquakes.
Also like the Crab, its surface appears quiescent, free from the starquakes that rumble through magnetars.
They suggested other stars which also produce flares releasing X-ray radiation might be shaken by even more powerful "starquakes".
So magnetars--neutron stars with powerful magnetic fields--might be the culprit, producing flares when starquakes break the magnetar's brittle crust.
"Detection of starquakes caused by such flares might be an interesting challenge for stellar astronomy."
A fairly direct age measurement comes from starquakes, which create pulsations in brightness that change as the star ages.
