Stellar Seismology: Listening To A Star's Secrets

Science & Reason on Facebook: tinyurl.com CoRoT reveals a magnetic activity cycle in a Sun-like star: Using data captured by the CoRoT satellite, scientists have successfully probed a distant star, using a technique called stellar seismology to monitor the star's acoustic fluctuations. They detected "starspots"-areas of intense magnetic activity on the surface that are similar to sunspots. While scientists had previously observed these magnetic cycles in other stars, this was the first time they discovered such a cycle using stellar seismology. --- Please subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com • www.youtube.com --- Distant star's sound waves reveal cycle similar to the Sun's: In a bid to unlock longstanding mysteries of the Sun, including the impacts on Earth of its 11-year cycle, an international team of scientists has successfully probed a distant star. By monitoring the star's sound waves, the team has observed a magnetic cycle analogous to the Sun's solar cycle. The study, conducted by scientists at the National Center for Atmospheric Research (NCAR) and colleagues in France and Spain, is being published as a "Brevia" in Science. Distant star's inner secrets revealed by sound waves. Using data captured by the Convection Rotation and planetary Transits (CoRoT) satellite, scientists have successfully probed a distant star, using a technique called stellar seismology to monitor changes in the star's sound waves. Using that ...
