What’s Up with That reports that:
Distant Star’s Sound Waves Reveal Cycle Similar to Sun – but the cycle is fast, less than 1 year
Star known as HD49933 is located 100 light years away from Earth
In a bid to unlock long-standing 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.
Results of the study, conducted by scientists at the U.S. National Center for Atmospheric Research (NCAR) in Boulder, Colo., and colleagues in France and Spain, are published this week in the journal Science.
