The nucleus of the sun rotates four times faster than its surface

New solar observations based on gravitational waves inside the star revealed that the nucleus of the sun rotates four times faster than its surface.

Scientists using the solar observatory of the European Space Agency ( NASA ) and NASA ( SOHO) have discovered gravitational waves in the interior of the sun, revealing a rapid nucleus rotation.

A team of international researchers arrived at this sudden discovery, previously assuming that the nucleus of the sun rotates at the same surface velocity.

The researchers explained that the source of internal rotation, unexpected, may return to billions of years.

"The most likely explanation for this phenomenon is that the nucleus rotation on this pattern has started since the formation of the sun, about 4.6 billion years ago," said Roger Ulrich, professor of astronomy and co-author of the study, published in the journal Astronomy and Astrophysics.

The research team relied on data more than 16 years old, compiled by the SOHO tool to detect "low-frequency global oscillations" (GOLF), which are usually difficult to detect.

The SOHO spacecraft was launched in 1995 to study the sun from its core to the outer corona and solar wind.

The researchers were able to determine the time it takes for the waves to reach the center of the sun and return back to the surface, by measuring the sound waves.

The results indicate that the nucleus rotates once a week, approximately 4 times faster than the surface and medium layers.

Scientists also found a significant difference in temperature between the sun's nucleus and surface, with a temperature of about 29 million degrees Fahrenheit, or 15.7 million Kelvin, while the surface temperature is about 10,000 degrees Fahrenheit, or 5800 Kelvin.
