Luminosity can also be given in terms of the astronomical magnitude system: the absolute bolometric magnitude ( M bol) of an object is a logarithmic measure of its total energy emission rate, while absolute magnitude is a logarithmic measure of the luminosity within some specific wavelength range or filter band. In astronomy, values for luminosity are often given in the terms of the luminosity of the Sun, L ⊙. In SI units, luminosity is measured in joules per second, or watts. In astronomy, luminosity is the total amount of electromagnetic energy emitted per unit of time by a star, galaxy, or other astronomical objects. ![]() ![]() Luminosity is an absolute measure of radiated electromagnetic energy (light) per unit time, and is synonymous with the radiant power emitted by a light-emitting object. A star with four times the radiative power of the Sun has a luminosity of 4 L ⊙. In astronomy, this amount is equal to one solar luminosity, represented by the symbol L ⊙. The Sun has an intrinsic luminosity of 3.83 ×10 26 watts. For other uses, see Luminosity (disambiguation). ![]()
