And blue supergiant stars—as their name would suggest—are huge, with masses anywhere upwards of 10 times that of our Sun. When they run out of hydrogen, they start to use helium in their cores, which causes the star to burn hotter and brighter. Luke Dodd/Science Photo Library/Getty Images. The blue supergiant lies 9 billion light-years away Icarus, the most distant star ever detected (NASA, ESA, and P. Kelly, University of Minnesota) By Jason Daley n. A supergiant star with surface temperature ranging from 10,000 to 40,000 kelvin , making the star appear blue-white The most massive ones could make 100 Suns (or more!). However, their size can vary a lot. As we mentioned above, supergiants will eventually die as supernovae. The best known example is Rigel, the brightest star in the constellation of Orion. When a blue supergiant star explodes in a supernova, it can spawn exotic states of matter like quark-gluon plasma, scientists have found. Blue supergiants (BSG) are massive stars which end their lives with violent supernova explosions. The two most common types are supergiants are blue supergiants, such as Rigel, and red supergiants, such as Betelgeuse. They are extremely hot and bright, with surface temperatures of between 20,000 - 50,000 degrees Celsius. ThoughtCo uses cookies to provide you with a great user experience. Blue supergiants are among that second group. By using ThoughtCo, you accept our. For example, the bright star Rigel in Orion is one and there are collections of them at the hearts of massive star-forming regions such as the cluster R136 in the Large Magellanic Cloud. At that point, the star is nearing the end of its life and will soon (on timescales of the universe anyway) experience a supernova event. As the star fuses heavier and heavier elements in its core, the fusion rate can vary wildly. Blue supergiants synonyms, Blue supergiants pronunciation, Blue supergiants translation, English dictionary definition of Blue supergiants. In reality, when it comes to turning the tap, astrophysics doesn’t apply; blue stars are actually hotter than red stars! Effects: Multiplies Ores by 15x (200x with Nova Star) Effect Cap: $1 TsTG Hubble Space Telescope image of the Crab Nebula. Since there is no clear definition of blue giant stars, the term is frequently applied to any hot, massive star, albeit erroneously in some cases. That's a science called astrophysics. Define blue supergiant. Blue Supergiant - a snapshot of the interior of a star three times as heavy as our sun which shows waves generated by turbulent core convection. [1] Contents. Blue supergiants also have very fast, thin stellar winds blowing away into space. The surface of the star is red, which according to Wien's Law, is a direct result of a low surface temperature. They are scattered across the night sky. Supernova explosions occur at the end of a star's life. $\begingroup$ Just to clarify, the question of whether or not a planet could develop life in the lifespan of a blue supergiant does not matter. These bright and hot stars are roughly the size of 20 solar masses. Could We Harness Energy from Black Holes? They are characterized by high temperatures ranging from 20,000 – 50,000 kelvin (35,540.3 – 89,540.3 °F). [/caption] If our Sun is an average sized star, there are some true monsters out there. The term giant star was first coined by Hertzsprung when it became apparent that the majority of stars fell into two distinct regions of the Hertzsprung–Russell diagram. For more information, see the following related content on ScienceDaily: Content on this website is for information only. Despite their rarity and their short lives blue supergiant stars are heavily represented among the stars visible to the naked eye; their inherent brightness trumps their scarcity. What is a blue supergiant? Rigel, Beta Orionis (β Ori), is a blue-white supergiant star located in the constellation Orion, the Hunter. (It's worth knowing that being massive isn't always the same as being large. Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. (Part I) Typically people think of blue being cold, and red being hot. High-mass stars may also employ the carbon-nitrogen-oxygen (CNO) cycle to help drive the reactions. Blue supergiant stars … It is not intended to provide medical or other professional advice. However supergiants can range from spectral typecool, red class M stars to very hot, blue class O stars. Blue supergiant stars open doors to concert in space Almost all blue supergiants shimmer in brightness because of waves on their surface Date: May 6, 2019 Financial support for ScienceDaily comes from advertisements and referral programs, where indicated. An international team of scientists led by KU Leuven in Belgium described blue giants as the “metal factories of the universe” and have been shown to produce all chemical elements beyond helium in the Periodic … Blue supergiants are supergiant stars (class I) of spectral type O. For low- and medium-mass stars, that step causes them to evolve into red giants, while high-mass stars become red supergiants. Blue supergiant star is similar to these topics: Supergiant star, Red supergiant star, Yellow supergiant star and more. The title supergiant, as applied to a star, does not have a single concrete definition. They’re the supergiant stars, and they come in two flavors: red and blue. Blue supergiant stars are amongst the largest and brightest stars in the world. At this point, the star can contract in on itself during periods of slow fusion, and then become a blue supergiant. Items Needed: 10 Blue Supergiants. Origin and definition. As a result, the average surface temperature is only 3,500 - 4,500 Kelvin. This causes the outer lays of the star to expand outward due to the increased heat generated in the core. Edited and updated by Carolyn Collins Petersen. In 1956, the astronomers Feast and Thackeray used the term super-supergiant (later changed into hypergiant) for stars with an absolute magnitude brighter than M V = −7 (M Bol will be larger for very cool and very hot stars, for example at least −9.7 for a B0 hypergiant). The model shows the inhomogeneous circumstellar medium around Sanduleak -69° 202, the progenitor BSG of supernova (SN) 1987A, immediately before the collapse of the core. Rigel, seen at the bottom right, in the constellation Orion the Hunter is a blue supergiant star. It's not uncommon for such stars to oscillate between the red and blue supergiant stages before eventually going supernova. It became visible on Earth in the year 1054 and can still be seen today through a telescope. Some live long and prosper while others are born on the fast track. Although the progenitor star of the Crab may not have been a blue supergiant, it illustrates the fate awaiting such stars as they near the ends of their lives. When they do, the final stage of their evolution can be as a neutron star (pulsar) or black hole. With an apparent magnitude of 0.13, it is… They are extremely hot and bright, with surface temperatures of between 20,000 - 50,000 degrees Celsius. For all stars, the primary nuclear fuel is hydrogen.

The best-known is the Crab Nebula, where a star exploded thousands of years ago. Most have at least ten times the mass of the Sun and many are even more massive behemoths. Due to core nuclear reactions being slightly slower, the star contracts and since very similar energy is coming from a much smaller area (photosphere) then the star's surface becomes much hotter.
