Betelgeuse is a red supergiant star in the constellation of Orion. It is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in its constellation. It is a distinctly reddish, semiregular variable star whose apparent magnitude, varying between +0.0 and +1.6, has the widest range displayed by any first ...
If Betelgeuse were too close to Earth, the eventual supernova could cause an extinction here on Earth. However, even at 530 light-years distance, our planet will still be safe from the eventual ...
A number of close or well-known stars have been identified as possible core collapse supernova candidates: the high-mass blue stars Spica and Rigel, [240] the red supergiants Betelgeuse, Antares, and VV Cephei A; [241] [242] [243] the yellow hypergiant Rho Cassiopeiae; [244] the luminous blue variable Eta Carinae that has already produced a ...
As Betelgeuse burns through fuel in its core, it has swollen to massive proportions, becoming a red supergiant, the latter phase of giant stars. When the star explodes, the event could be briefly ...
Antares B is a magnitude 5.5 blue-white main-sequence star of spectral type B2.5V; it also has numerous unusual spectral lines suggesting it has been polluted by matter ejected by Antares. [7] It is assumed to be a relatively normal early-B main sequence star with a mass around 7 M ☉ , a temperature around 18,500 K , and a radius of about 5 R ...
