A blue supergiant (BSG) is a hot, luminous star, often referred to as an OB supergiant. They are usually considered to be those with luminosity class I and spectral class B9 or earlier, [ 1 ] although sometimes A-class supergiants are also deemed blue supergiants.
Mar 26, 2024 · B-type blue supergiant stars are at least 10,000 times brighter, two to five times hotter and 16 to 40 times more massive than the sun. Blue supergiants are so extreme that scientists have...

Blue supergiants are born massive. Think of them as the 800-pound gorillas of the stars. Most have at least ten times the mass of the Sun and many are even more massive behemoths. The most massive ones could make 100 Suns (or more!). A star that massive needs a lot of fuel to stay bright. For all stars, the primary nuclear fuel is hydrogen. When th...
That's the executive summary of a blue supergiant. Digging a little deeper into the science of such objects reveals a lot more detail. To understand them, it's important to know the physics of how stars work. That's a science called astrophysics. It reveals that stars spend the vast majority of their lives in a period defined as "being on the main ...
While red supergiants are the largest stars, each with a radius between 200 and 800 times the radius of our Sun, blue supergiants are decidedly smaller. Most are less than 25 solar radii. However, they have been found, in many cases, to be some of the most massivein the universe. (It's worth knowing that being massive isn't always the same as being...
As we mentioned above, supergiants will eventually die as supernovae. When they do, the final stage of their evolution can be as a neutron star (pulsar) or black hole. Supernova explosions also leave behind beautiful clouds of gas and dust, called supernova remnants. The best-known is the Crab Nebula, where a star exploded thousands of years ago. I...
Blue supergiants are very massive stars that burn bright and hot for a short time before exploding as supernovae. They are among the most luminous and rare objects in the universe, and can be found in star-forming regions like the Large Magellanic Cloud.
Feb 3, 2009 · The most massive stars in the Universe are the blue supergiant stars; then can have more than 20 times the mass of the Sun. Blue giant stars are very hot, with surface temperatures of...
Jul 27, 2024 · B-type blue supergiants are highly luminous, massive stars that defy traditional expectations by frequently appearing despite their theoretically brief evolutionary phase. Recent research provides new insights, showing that many blue supergiants likely form from the merger of massive binary systems.
May 6, 2019 · The detectable progenitors of supernovae include blue supergiant stars, which are hot massive stars in a shell-hydrogen or core-helium burning stage of stellar evolution.
