Astronomers Take a Look Inside Red Giant Stars

Recent developments in the Kepler mission have found data that can help humans understand the workings and dynamic of Red giant Stars. The mission returned evidence of a regular changes in the brightness of the star. "Their regularity resembles steady drumbeats at different, precise rhythms." However, they did notice certain anomalies in the way the beats carried out. These other patterns were caused by gravity. The waves caused by these patterns are allowing the instruments aboard the Kepler mission to probe deep into the red giant star to understand more about the nature of its chemistry and density. The information is also allowing astronomers to understand more about the life cycle of stars.

This could be a critical boost for astronomers. By now being able to view red giant stars so clearly, astronomers have the chance to really understand the life cycle of these stars and make more accurate predictions. Additionally, now that they can tell whether the star burns hydrogen in its shell or helium in its core allows astronomers to differentiate between stars in the solar system.

Very interesting article, it reaffirms the role of hydrogen and helium in our galaxy. This can also act as support for the nebular theory.
