WebThe luminosity of the Sun is a measure of how much energy the Sun produces per unit time. It is obtained by multiplying the solar intensity by the Sun's surface area: , where represents the radius of the Sun.
Web13 jun. 2024 · The masses of stars are measured in solar masses—abbreviated as M ⊙. One M ⊙ is exactly the mass of the sun. 2 M ⊙ is twice the mass of the sun…and so on. As we plot stellar masses on the H-R diagram, we begin to notice a pattern right away—at least, that is, in the main-sequence stars. The greater the mass, the more luminous the … Web4/5/20249:00:00 AM.
