Super Giant (スーパー・ジャイアンツ 鋼鉄の巨人, Sūpā Jaiantsu) a.k.a. The Steel Giant, is a 1957 black and white Japanese film directed by Teruo Ishii. Plot: Super Giant first appears on Earth to stop foreign terrorists who threaten to destroy Japan (and the rest of the world) with an atomic bomb. (Part 1 of 2).
The phase where these stars have both hydrogen and helium burning shells is referred to as the asymptotic giant branch (AGB), as stars gradually become more and more luminous class M stars. Stars of 8-10 M ☉ may fuse sufficient carbon on the AGB to produce an oxygen-neon core and an electron-capture supernova, but astrophysicists categorise ...
Some of the brightest stars in the night sky, such as Rigel and Antares, are in the list. While supergiants are typically defined as stars with luminosity classes Ia, Iab or Ib, other definitions exist, such as those based on stellar evolution. [1] Therefore, stars with other luminosity classes can sometimes be considered supergiants.
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.

Red supergiants have masses between about 10 M ☉ and 30 or 40 M ☉. [10] Main-sequence stars more massive than about 40 M ☉ do not expand and cool to become red supergiants. Red supergiants at the upper end of the possible mass and luminosity range are the largest known.
AH Scorpii is a dust-enshrouded red supergiant [10] and is classified as a semiregular variable star with a main period of 714 days. The total visual magnitude range is 6.5 - 9.6. [ 2 ] No long secondary periods have been detected. [ 11 ]
Colour-Magnitude Diagram showing evolutionary tracks for stars in the super-AGB mass range. A super-AGB star is a star with a mass intermediate between those that end their lives as a white dwarf and those that end with a core collapse supernova, and properties intermediate between asymptotic giant branch (AGB) stars and red supergiants.
