Unlocking the Secrets of Giant Stars: The Twinkle of a Star Reveals Its Innermost Secrets
Astronomers have made an exciting discovery about the stars in our universe. Using a new technique, they have been able to observe the inside of a giant star, known as a pulsar, by tracking its twinkling. This new data will allow astronomers to gain valuable insights into the inner workings of stars.
Pulsars are the collapsed cores of giant stars that have gone supernova. They emit beams of radiation that can be seen from Earth as a regular, rhythmic pulse, and are among the most exotic objects in the universe. By carefully observing the twinkling of a pulsar, astronomers have been able to map out its inner structure.
The twinkling is caused by variations in the density of the star’s material, and the resulting changes in brightness are caused by the Doppler shift of the light the star emits. By carefully tracking these changes, the researchers were able to map out the interior of the star. This new data will be used to help astronomers better understand the life cycle of stars and the forces that shape them.
