New analysis of planets orbiting in habitable zones of small stars estimates minimum planetary magnetic field to protect their atmospheres

Star system: TOI 700 | Distance from the Sun: 102 light years

Exoplanets Kepler 186 f and TOI 700 d might have magnetic fields sufficiently strong to protect their atmospheres and surfaces from stellar magnetic fields.
