Etymology
Borrowed from French luminosité or else a native formation from luminous + -ity.
Meanings
-
(uncountable) the state of being luminous, or a luminous object; brilliance or radiance
They reported encountering a luminosity of great intensity and loving angelic beings.
1994, Simcha Paull Raphael, Jewish Views of the Afterlife, page 360:
- (countable, uncountable) the ratio of luminous flux to radiant flux at the same wavelength; the luminosity factor
-
(countable, uncountable) The rate at which a star radiates energy in all directions.
We recognize the same pattern as in the left panel, with dM stars being much less frequent flarers than dMe stars of similar luminosity.

Schmitt, Activity in Cool Star Envelopes: Proceedings, page 56:We derive rotation periods, photometric activity indices, flaring energies, mass loss rates, gyrochronological ages, X-ray luminosities and consider implications for the planetary magnetospheres and habitability.
