WebD L - luminosity distance, obtaining an objects distance using only visual aspects; Galaxy comparison. Galaxy type and spectral comparison: see galaxy morphological classification; Luminosity comparison. Luminosity comparison: L S, L ☉ - luminosity of the Sun (Sol) Luminosity of certain object: L acc - accretion luminosity; L bol - bolometric ... The Sun is a weakly variable star, and its actual luminosity therefore fluctuates. The major fluctuation is the eleven-year solar cycle (sunspot cycle) that causes a quasi-periodic variation of about ±0.1%. Other variations over the last 200–300 years are thought to be much smaller than this. See more The solar luminosity (L☉), is a unit of radiant flux (power emitted in the form of photons) conventionally used by astronomers to measure the luminosity of stars, galaxies and other celestial objects in terms of the output … See more Solar luminosity is related to solar irradiance (the solar constant). Solar irradiance is responsible for the orbital forcing that causes the Milankovitch cycles, which determine Earthly glacial cycles.
