  5. Luminosity is a measurement of brightness.
  6. emitting light; glowing brightly; brightly illuminated
  7. (luminously) In a luminous manner, brightly, glowingly
  8. (luminosity) the state of being luminous, or a luminous object; brilliance or radiance; the ratio of luminous flux to radiant flux at the same wavelength; the luminosity factor; the rate at which a star radiates energy in all directions
  9. (luminosity) The rate at which a star or other object emits energy, usually in the form of electromagnetic radiation.
  10. (Luminosity) Main sequence stars cool, but eventually reach a minimum luminosity which they can sustain through steady fusion. This varies from star to star, but is generally at least 0.01% the luminosity of our Sun. ...
  11. (Luminosity) A value corresponding to the brightess of color.
  12. (luminosity) This figure of merit for an accelerator quantifies the intensity of the beams. It is directly related to the number of events produced at the machine.
  13. (Luminosity) The amount of light emitted by a star.
  14. (luminosity) The power of a light source; the amount of energy it emits each second. In ordinary life, we measure luminosity in watts (W): a light bulb may emit 100 Watts. The Sun emits about 4 x 10^(26) Watts. ...
  15. (Luminosity) A quality seen in some paintings of a glow coming from within, the illusion that there is actually a light coming out of the picture. Glossy colors are more likely to provide this luminous effect than matte colors.
  16. (Luminosity) Brightness or intensity of either a light source or reflective surface.
  17. (Luminosity) Fancy word for how bright something is.
  18. (Luminosity) In Poltergeists and the Paranormal: Fact Beyond Fiction, Doctors Philip Stander and Paul Schmolling mention luminosity as a sort of poltergeist phenomena. They are small bright lights that suddenly appear and hover, with no scientific explanation or logical cause.
  19. (Luminosity) Much like glow, luminosity is a measure of how much light a surface gives off before any light strikes it. This effect can be used to create an object that gives off its own light.
  20. (Luminosity) On some analogue watches, the numbers or number indicators such as dots or dashes are painted with a glow in the dark paint. When the paint, usually a phosphor or phosphor pigment, is exposed to light, it will store the light and be visible in the dark for a period of time. ...
  21. (Luminosity) Refers to hue’s inherent light; lighter colors are more luminous than darker colors, but a lighter color is not necessarily more saturated.
  22. (Luminosity) The amount of energy radiated into space every second by a celestial object, such as a star. It is closely related to the absolute brightness of a celestial object.
  23. (Luminosity) The introduction of ‘Spirit Light’ into the darkened séance room, allowing sitters to see Spirit communicators and associated phenomena.
  24. (Luminosity) The relative quantity of radiation emitted by a light source.
  25. (luminosity) n. The brightness of a color based on a scale from black to white on your monitor.
