L☉の説明

Translingual Alternative forms The L is not always italic. Etymology L (luminosity) and subindex ☉ (sun). Symbol L☉ (astronomy) solar luminosity: a unit of measurement, equal to the luminosity of the sun. A typical large galaxy at z < 0.1 has a luminosity of about 1010 L☉. The luminosity of the sun specifically.

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 of the Sun. One nominal solar luminosity is defined by the International Astronomical Union to be 3.828×1026 W. 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.
