Webb12 sep. 2015 · Lower mass main sequence stars would not have departed significantly from their initial main sequence radii even if they were as old as the Galaxy. The radius will also depend on the chemical composition - both the overall metallicity and the fractional helium abundance are important, through their effects on atmospheric opacities and … Webb28 okt. 2024 · Main sequence stars are powered by the fusion of hydrogen (H) into helium (He) in their cores, a process that requires temperatures of more than 10 million Kelvin. Around 90 percent of the stars in the Universe are main sequence stars, including our sun. Main sequence stars typically range from between one tenth to 200 times the Sun’s mass.

Answer 7 - The main sequence is a band of stars on the Hertzsprung-Russell (HR) diagram, a graph that plots a star's luminosity (or brightness) against its surface temperature. Along the main sequence, stars range in size from small, cool, and dim red dwarfs to large, hot, and luminous blue giants.
