The exoplanet GJ 215 c. Can host lifeforms in the future.

 

“An international team of scientists dubbed the exoplanet, named GJ 251 c, a “super-Earth” as data suggest it has a rocky composition similar to Earth and is almost four times as massive.

The new exoplanet. From 18 ly. away from Earth, can have liquid water on its surface. The exoplanet  GJ (Gliese) 251 c orbits the M-class star in a potentially habitable zone. The  GJ 251 c is a massive super-Earth that orbits the star GJ 215. That star has a spectral classification of M3V, and its age is about 6,6 GYR (Gigayears). Or, a simpler saying. 6,6 billion years. This means that. This M3V is still in its flare period. And there might not be lifeforms. On that exoplanet. Life formation begins after the flare period. The GJ 215 has two exoplanets. GJ 215b, whose mass is ≥ 3.85+0.35−0.33 Earth masses. And GJ 215 c, whose mass is ≥3.84±0.75 Earth masses. 

This means lifeforms start to advance later than on planets. That orbit the Sun (G2) type stars. But otherwise, the red dwarfs can live Tens to hundreds of billions of years. That means life has more time to advance on those planets than on planets that orbit G2V-type stars. In the future. The GJ215c might host. 

Even intelligent lifeforms.  But today, its star is too unstable for that. Those hypothetical civilizations require more mature stars. The problem with the red dwarf planets and technocivilization. This is how long radioactive isotopes can exist on those planets. There is a possibility that some of those planets run out of their fissile material. 

And their cores start to cool. That cooling process destroys the planet’s magnetic field. Those super-Earths that orbit M-type stars give a hint. About the possibility of lifeforms. Those super-Earths with a dense atmosphere can host life, but the star must be mature enough that it has ended its flare period. Those flares that the young red dwarfs create. It can raise. Those planets' temperatures. Into thousands of degrees. 

The atmosphere of those locked planets smooths their atmosphere’s temperature. All red dwarf-star planets that are in the habitable zone are locked. The tidal forces from the star lock the planet into position. There, it turns the same side to that star all the time. There is forever night in the side that is away from its star. And the other side is burning hot. The water and atmosphere, along with clouds, can smooth that effect. But that requires. The star will not create. It's flares anymore.
