1. How heavy is Quasi-star?Potentially ranging from thousands to millions of solar masses
2. What is a quasi-star?A quasi-star is a huge, bright object from the early universe that has a black hole inside it. The black hole pulls in gas, and that gas makes the quasi-star glow instead of using nuclear fusion.
3. How does a quasi-star form?It starts when a huge cloud of hydrogen and helium collapses. A tiny black hole appears in the center and pulls in gas very fast, making the whole thing grow huge.

Population III Stars: The first generation of stars in the universe, composed almost entirely of hydrogen and helium.
Nucleosynthesis: The process by which new atomic nuclei are created from pre-existing nucleons and nuclei.
Epoch of Reionization: A period in the early universe when the first stars and galaxies ionized the neutral hydrogen gas.
Protostar: A young, developing star that has not yet begun nuclear fusion in its core.
