Astronomers show magnetic field of a red dwarf star may be approaching polar reversal

The 11-year solar activity cycle is a well-known phenomenon, during which the intensity of the sun’s magnetic field varies and its polarities reverse. Over the past 30 years, astronomers have identified similar behavior in several sun-like stars. But until now, no reversal of magnetic polarities has been observed for their cooler counterparts, the red dwarf stars.
