Fluid dynamics simulations of a red giant, with giant convection cells and puffy surface. A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses (M ☉)) in a late phase of stellar evolution.
This is a list of the nearest giant stars (luminosity class III or II) ... The nearest M-type red giant, and the 25th brightest star in the night sky. 36 G. Doradus:
A red giant is a luminous giant star of low or intermediate mass that is in a late phase of its evolution. Subcategories This category has the following 7 subcategories, out of 7 total.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [95] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [101] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [102]
Higher-mass stars never cool sufficiently to become red supergiants. Lower-mass stars develop a degenerate helium core during a red giant phase, undergo a helium flash before fusing helium on the horizontal branch, evolve along the AGB while burning helium in a shell around a degenerate carbon-oxygen core, then rapidly lose their outer layers ...
Of those, 103 are main sequence stars: 80 red dwarfs and 23 "typical" stars having greater mass. Additionally, astronomers have found 6 white dwarfs (stars that have exhausted all fusible hydrogen), 21 brown dwarfs, as well as 1 sub-brown dwarf, WISE 0855−0714 (possibly a rogue planet ).
This red giant star will, one day, explode as a supernova. Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star ...
Within any giant luminosity class, the cooler stars of spectral class K, M, S, and C, (and sometimes some G-type stars [13]) are called red giants. Red giants include stars in a number of distinct evolutionary phases of their lives: a main red-giant branch (RGB); a red horizontal branch or red clump; the asymptotic giant branch (AGB), although ...
