So the right way to think about an H-R Diagram. It is telling us that a star’s color (or temperature) and its luminosity are related. Blue stars are more luminous than red stars.

WebJun 6, 2008 · The red giant stars, with magnitudes of 1 and less, are apparent in this diagram. The shape of this HR Diagram suggests that the stars in 47 Tuc are 13 billion years old, which means they 80% of the universe's age. The Hertzsprung-Russell Diagram for stars of the globular cluster Tuc 47. 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 … See more 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 See more 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.
