Quasi star luminosity
Quasi-stars are predicted to have surface temperatures higher than 10,000 K (9,700 °C). At these temperatures, and with radius of approximately 10 billion kilometres (67 au), or 14,000 times that of the Sun, each one would be about as luminous as a small galaxy. See more A quasi-star (also called black hole star) is a hypothetical type of extremely massive and luminous star that may have existed early in the history of the Universe. Unlike modern stars, which are powered by nuclear fusion in … See more A quasi-star would result from the core of a large protostar collapsing into a black hole, where the outer layers of the protostar are massive enough to absorb the resulting burst of energy without being blown away or falling into the black hole, as occurs with modern See more • Accretion • Accretion disk • Blitzar • Thorne–Żytkow object See more WebAug 19, 2024 · A quasi-star compared to many large stars (UY Scuti is not the largest star, and even Stephenson 2-18 is actually smaller than a Quasi Star but Quasi stars are hypothetical, so they are just ideas, and likely not existent). Below is a list of the largest stars, so far discovered, ordered by radius.
