We just learned that Planets around red dwarfs are common. Some are orbiting their star from a very short distance , may be inside the habitable zone. But there is problem about their habitability , they are probably tidally locked to their star , like our moon is locked to Earth.
So I wandered if there were possibly an other factor able to keep these planets turning. And I found one possible suspect : the magnetic field.
A planet in the habitable zone of a red dwarf is about 100 times nearer that its star than Earth , so the magnetic filed should be 10,000 stronger . (Inverse square law).
Is it possible that the interaction of the star magnetic field , with the planet magnetic field , keeps it running , even at a slow rate ?
