R136a1 is expected to lose almost all its spin long before core collapse so a GRB is unlikely. [37] The remnant from a type Ic core collapse supernova is either a neutron star or black hole, depending on the mass of the progenitor core. For a star as massive as R136a1, the remnant will very likely be a black hole instead of a neutron star. [38]
UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum. It is also a pulsating variable star , with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [74] AD ρ Cassiopeiae: 564 ± 67 or 700 ± 112 [75] AD
The central R136 concentration of the cluster is about 2 parsecs across, although the whole NGC 2070 cluster is much larger. [8] R136 is thought to be less than 2 million years old. [8] [9] None of the member stars are significantly evolved, and none are thought to have exploded as supernova. Because of this, the cluster contains no red ...
The first star in the list, Godzilla [1] — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the 19th ...
UY Scuti is a red supergiant and is also one of the largest stars currently known with a radius over 900 times that of the Sun. [11] RSGC1-F01 is another red supergiant whose radius is over 1,450 times that of the Sun. [12] Scutum contains several clusters of supergiant stars, including RSGC1, [13] Stephenson 2 [14] [15] and RSGC3. [16]
Stephenson 2 DFK 1, also known as RSGC2-01 [a] or St2-18, is a red supergiant (RSG) or possible extreme red hypergiant [2] (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a ...
The star loses 4.6 × 10 −5 solar masses per year through a stellar wind with a speed of 2,400 km/s. [5] [12] The high mass of the star compresses and heats the core and promotes rapid hydrogen fusion predominantly through the CNO process, leading to a luminosity of 5,129,000 L ☉. The fusion rate is so great that in 10 seconds R136a2 ...
