Miniature red dwarf planetary systems should be 20 or more common then solar type stars.

Combined with the fact that they can exist for up to 10 trillion years, red dwarf systems are considered a prime candidate in the search for habitable exoplanets.
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).
Astronomers estimate that billions of habitable planets are orbiting red dwarf stars. The second study was conducted by ravi kumar kopparapu, an exoplanet will spend time listening for extraterrestrial signals from red dwarf syst.
But here is my other assumption: probably a more concentrated (almost point source) of gravity from smaller red dwarf stars locks planets more effectively than a broad giant star. (it is kind of analogous to a small speaker magnet that has stronger magnetic field compared to the earth's magnetic field when measured).
In habitable exoplanets: red dwarf systems like trappist-1, you will discover some of the constraints and chances of planets being habitable around the most abundant type of star in the universe – red dwarfs.

Much longer life, trillion of years, for every sun like star 14 red dwarfs and twice as many habitable planets around them. They provide a giant habitable space, compared to the over luminosities for the immature giants. Do not be taken in by the dazzling bright lights but look to the steady glow of infinitely powerful m dwarfs.
A newly published study reveals that habitable zones near red dwarf stars may be smaller than previously thought. The researchers believe that the exoplanets orbiting the red dwarfs may be mostly covered by icy crusts, save for somewhat lobster-shaped oceans on their day sides.

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.

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. The new studies also enlarge the size of the habitable zones in which exoplanets could be orbiting a red dwarf or other “cool” star, making more of them potentially habitable.

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.

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.
