Solar luminosity wikipedia
When not qualified, the term "luminosity" means bolometric luminosity, which is measured either in the SI units, watts, or in terms of solar luminosities (L☉). A bolometer is the instrument used to measure radiant energy over a wide band by absorption and measurement of heating. A star also radiates neutrinos, which carry off some energy (about 2% in the case of the Sun), contributing to the star's total luminosity. The IAU has defined a nominal solar luminosity of 3.828×10 W to pro… WebThe solar luminosity (L☉) is a unit of radiant flux (power emitted in the form of photons) used to measure the luminosity of stars, galaxies and other celestial objects in terms of the output of the Sun. 1 The International Astronomical Union (IAU) has defined a nominal solar luminosity of 3.828 × 1026 W. 2 Luminosity is an absolute measure of radiant power, and …
