Want this question answered?
Any stars less massive than our sun do not explode in a supernova. They will slowly cool down and burn out forming an "ember" (a.k.a. white dwarf).
The most massive stars will form ultra large stars, which will collapse into black holes upon their demise.
A black hole.
All of them
Massive
There are thought to be between 200 billion and 400 billion stars in our galaxy. So for every star, there could be several planets in orbit. This is just our galaxy though, there are then thought to be 100 billion galaxies or more, so total number of stars in the universe is massive.
As stars burn, they shed matter, becoming less massive slowly throughout their life cycle. This reduction in mass necessarily lessens their gravity, causing the stars' diameter to increase. So, many end-stage stars will be huge and bloated. Massive red giant stars are examples of this.
The massive stars turn into gas

Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
The pressure and temperature in the core of a star varies, depending on the star's mass. And the energy production is highly dependent on the temperature.
What I have learned about massive stars is...
Massive stars are most likely to explode faster than smaller stars.
Massive Stars Use Their Hydrogen Much Faster Than Stars Like The Sun Do.
Hydrogen, helium, and carbon fuel are found in more massive stars. The diameter of more massive stars is bigger. Helium is found in greater abundance in more massive stars. The weight of more massive stars is greater.
The most massive stars will form ultra large stars, which will collapse into black holes upon their demise.
