How do you account for its luminosity

WebApr 25, 2024 · Luminosity classes of stars are designated by Roman numerals and tell us what region of the H-R diagram the star falls in. We use both spectral type and luminosity class to completely classify stars; the spectral type tells us the star’s temperature while the luminosity class tells us its radius. How is luminosity class determined? WebThere is not a straightforward relation between a galaxy's luminosity and its mass. The luminosity depends on how much present and recent star formation there has been. …

F = L 4 π d 2 In this expression, d is the distance to an object, F is its flux (also known as apparent brightness, or intensity), and L is its luminosity (absolute or intrinsic brightness). canon printer with 21 ppm https://martinezcliment.com
