What Is a Main Sequence Star? A star whose characteristics place it in a band, called the main sequence, on an H-R diagram is called a main sequence star. The Hertzsprung-Russell (H-R) diagram is a diagram that plots a star's luminosity vs. surface temperature. Luminosity is the ...
The Sun is the closest star to Earth; however, many other stars are visible at night. One of the brightest stars in the night sky is Sirius, two stars in a binary system, Sirius A and Sirius B. It appears so bright because it has a high luminosity and is relatively close to the so...
while the hydrogen shell begins to expand. The star's luminosity, or brightness, increases by a factor of 1,000 to 10,000, while the hydrogen shell begins to burn cooler, taking on a red appearance and becoming a red giant. Red light is the lowest temperature of visible light, while ho...
