Star Tau Boo’s baffling magnetic flips
Royal Astronomical Society said:
In 2007, the magnetic field of Tau Boo was seen to flip: the first time this was observed to happen in a star other than the Sun. Since then the team has observed four reversals in polarity and is now able to confirm that the star has a rapid magnetic cycle of no more than two years – compared to 22 years for the Sun. This cycle will subject the orbiting hot-Jupiter to very fast changes in its surrounding environment. Dr Rim Fares will present findings at the National Astronomy Meeting in St Andrews on Thursday 4 July.
