The theorized habitability of red dwarf systems is determined by factors including tidal effects, flaring, and variability. Modern evidence suggests that planets in red dwarf systems are unlikely to be habitable, due to high probability of tidal locking, likely lack of atmospheres, and the high stellar variation many such planets would experience. However, many recent models have proposed mechanisms through which red dwarfs can mitigate these effects. Research suggests that magnetic fields can shield planets from solar flares and theoretical simulations have shown the possibility of atmospheric mechanisms that can redistribute heat from the dayside to the nightside. The sheer number and longevity of red dwarfs also provides ample opportunity to realize any small possibility of habitability.
