Sun’s core rotates 4 times faster than its surface
A team of global astronomers
recently found that the Sun's core rotates near four times faster than its
surface.
European Space Agency and NASA's Solar and
Heliospheric Observatory (SOHO), together, helped the solar scientists find
evidence of a type of seismic wave in the Sun.
These waves are known as g-modes and are
low-frequency waves. These waves revealed that solar core is actually rotating
four times faster than its surface.
The solar physicists used helioseismology to
study the Sun's interior structure by tracking the way waves move on the star.
The scientists used over 16 years of data
collected by SOHO's GOLF instrument (Global Oscillations at Low Frequencies).
The study was published in the journal Astronomy and Astrophysics.
The Sun’s core is important because it may
give a clue of how the Sun was formed.
