Washington, July 12 ( ANI ): A new technique called gyrochronology has helped the scientists to determine the accurate ages of the Sun-like stars from its rotation period.
TEHRAN (FNA)- A team of astronomers devised a new technique to measure the age of a star by using its spin -- gyrochronology.
Since the stars had a known age, astronomers could use them to calibrate the gyrochronology "clock".
If a relationship between stellar rotation and age can be established by studying stars in clusters, then measuring the rotation period of any star can be used to derive its age -- a technique called gyrochronology (pronounced ji-ro-kron-o-lo-gee).
