Supernovae would be more common
The very smallest "stars" in the galaxy are brown dwarfs. These are starlike objects that have failed to produce sustained nuclear fusion.
Same as all elements - in stars by nuclear fusion.
nuclear fusion would not occur
Stars are mostly hydrogen, the simplest element in the universe - also, the most common element in the universe. All the elements heavier than hydrogen were formed by nuclear fusion, where the atoms fuse together at very high temperatures and pressures. So carbon, oxygen, iron and everything else is like the "ash" from the nuclear "fire" in stars that once burned in other skies and then were destroyed in nova and supernova explosions.
During the life cycle of massive stars, when carbon fuses to form neon and magnesium.
They are called Core Burning Stars the smallest one is OGLE-TR-122b.
On Earth carbon is not synthesized, we have what we have.In the Sun carbon is not synthesized.In red giant stars carbon is synthesized by nuclear fusion of 3 helium nuclei to produce 1 carbou nucleus. However this carbon will remain inside the star.
Low-mass stars have little gravitational energy, so when they contract, they don't get very hot.

stars.... stars are made of hydrogen, helium, and nuclear fusion
-- In the cores of stars, where nuclear fusion reactions are taking place. -- Inside the casing of a nuclear weapon at the moment of detonation. -- In the fuel rods in the core of a nuclear power generating station. -- At the point of collision in the experimental target area in a particle accelerator.
Stars are not powered by combustion; they are powered by nuclear fusion, which is a fundamentally different and far more energetic process.
