Well isn't that just fantastic, our massive stars do go through quite the transformation! After the main-sequence stage, they can evolve into red supergiants, undergo a supernova explosion, and then slowly turn into either a neutron star or a black hole. Each stage reveals the true beauty of nature and its wondrous cycle of life and transformation. Isn't it just awe-inspiring?

No. Only massive stars can become supergiants.
The difference is in mass. Low to medium mass stars (up to about 8-10 solar masses) become white dwarfs. Massive stars (10 to 25 solar masses) become neutron stars. Stars above 25 solar masses tend to become black holes.
The final stage of supergiant stars is a supernova explosion. When these massive stars exhaust their nuclear fuel, they can no longer support their own gravity, leading to a catastrophic collapse of the core. This collapse results in a rebound effect that expels the outer layers, creating a bright and powerful explosion. Depending on the mass of the original star, the remnant can become a neutron star or a black hole.
False. Medium-sized stars become white dwarfs. Only the most massive stars form black holes.
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.

Sometimes if the conditions are just right a huge diamond! (the final stage of nucleosynthesis of stars that are not more massive is carbon Theoretically, they get dimmer and dimmer until they become "black dwarfs".

No. Only massive stars can become supergiants.
Stage 4 of stellar evolution, which typically involves the fusion of heavier elements in massive stars, ends when the core iron collapses, leading to a supernova. This transition to stage 5, characterized by the remnants of supernovae or the formation of neutron stars or black holes, occurs within a few million years after stage 4 ends. Therefore, stage 4 ended and stage 5 began approximately a few million years ago in the life cycle of massive stars.
The most massive stars become black holes.
False. Only the most massive stars will become black holes.
In stage 4, a massive star undergoes hydrogen burning in its core, but it rapidly evolves into a red supergiant as it exhausts hydrogen and begins fusing heavier elements like helium. In contrast, an average star (like our Sun) remains on the main sequence for a longer period, primarily fusing hydrogen into helium without expanding significantly. Eventually, while an average star will swell into a red giant and shed its outer layers, a massive star will continue to fuse elements up to iron before undergoing a supernova explosion. This fundamental difference in evolution leads to varying end states: average stars become white dwarfs, while massive stars leave behind neutron stars or black holes.
