However, that does not mean that red dwarf stars are good candidates for hosting habitable planets.
Trappist-1, a compact star system that made waves in 2017, is notable for containing several earth-like planets orbiting in the star’s habitable zone. Around 80% of all stars in our galaxy are red dwarfs, making them extremely important in the search for habitable planets, yet their low luminosities make exoplanets hard to detect (for more, see this article and this astrobite on detection methods).

(it is kind of analogous to a small speaker magnet that has stronger magnetic field compared to the earth's magnetic field when measured).
But given proxima centauri is a cool, small red-dwarf star, it means this habitable zone is very close to the star; much closer in than mercury is to our sun, he said.

The habitability of red dwarf systems is presumed to be determined by a large number of factors from a variety of sources. Although the low stellar flux, high probability of tidal locking, small circumstellar habitable zones, and high stellar variation experienced by planets of red dwarf stars are impediments to their planetary habitability, the ubiquity and longevity of red dwarfs are factors which provide ample opportunity for any possibility of habitability to be realized.
The other found that these red dwarf exoplanets could have atmospheres that are always heavily clouded, but could still have surface temperatures that are moderate.

Carl sagan famously called our planet a “pale blue dot;” the red dots are the red dwarf stars within 16 light-years of earth. The red dots approach — zeroing in on one star at a time — has yielded other exciting discoveries, including that of a potentially rocky planet orbiting our nearest stellar neighbor, proxima centauri. Some 15 exoplanet systems are known within 16 light-years, most of them around red dwarfs, also called m-type stars.
That question has been near the top of the list for many exoplanet scientists, especially those involved in the search for habitable worlds. Red dwarfs are plentiful (about three-quarters of all the stars out there) and the planets orbiting them are easier to observe because the stars are so small compared to our sun and so an earth-sized planet blocks a greater fraction of starlight.
Very clear and concise discussion of red dwarf systems and the possibility of habitable planets. Written in a way that can be understood by just about anyone this book discusses the possibility of life around such suns.
