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. The outer atmosphere is inflated and tenuous, making the radius large and the surface temperature around 5,000 K (4,700 °C; 8,500 °F) or lower. The appearance of the red giant is … Meer weergeven A red giant is a star that has exhausted the supply of hydrogen in its core and has begun thermonuclear fusion of hydrogen in a shell surrounding the core. They have radii tens to hundreds of times larger than that of the Meer weergeven Red giants with known planets: the M-type HD 208527, HD 220074 and, as of February 2014, a few tens of known K-giants including Pollux, Gamma Cephei and Iota Draconis Meer weergeven The Sun will exit the main sequence in approximately 5 billion years and start to turn into a red giant.

At this point, it leaves the main sequence. Then the pressure of fusion provides an outward thrust that expands the star several times larger than its original size, forming a red giant.
Web14 feb. 2024 · A red giant becomes a white dwarf when it runs out of fusable material. When a star of less than about 8 solar masses runs out of hydrogen in its core, the mainly helium core collapses and heats up.
