Dot Earth Blog: Astonishing Views of a Luminous, Bustling Planet 2011-11-13T22:51:06Z The area of the figure thus obtained would be a measure of the total luminosity on the same scale as the area of the luminosity curve from which it was derived. Colour Measurement and Mixture 2012-02-27T03:00:13.987Z To determine the relative sizes of the two stars, we take the ratio of the corresponding luminosities: Astronomy 2016-10-13T00:00:00Z It has been stated that the luminosity of the flame is due to the particles of carbon, which are separated out of the hydrocarbons in the gas, being raised to a white heat. Gas Burners Old and New 2011-11-07T02:00:20.003Z The luminosities of even the five smallest are from five to ten times that of the sun, while the largest are one hundred times greater in light-giving power than our own luminary. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z It was of no color, but an unwholesome luminosity radiated from its changing outlines—an all encompassing ever approaching thing of horror, it drew gradually nearer and nearer, engulfing him—smothering him. Snowdrift A Story of the Land of the Strong Cold 2011-10-23T02:00:22.547Z The determination of the luminosity of a coloured object, as compared with a colourless surface illuminated by the same light, is the determination of the second colour constant.

Astronomy 2016-10-13T00:00:00Z It is, then, to the heavy hydrocarbons which are part of it—insignificant as their amount may appear—that the luminosity of a gas flame is solely due. Gas Burners Old and New 2011-11-07T02:00:20.003Z Dr. Shapley has kindly added column 12, giving the absolute magnitudes of the stars, that of the sun being 4.8, and column 13, showing their luminosity or absolute radiation, that of the sun being unity. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z The visual agent surrounding us had a permanent, self-existing luminosity, and was a pervading, bright, unreachable essence that, without an obvious origin, diffused itself equally in all directions.

Colour Measurement and Mixture 2012-02-27T03:00:13.987Z It is then reasonable to conclude that this distant star is likely to be a main- sequence star just like the Sun and to have the same luminosity as the Sun. Astronomy 2016-10-13T00:00:00Z The common distinction between luminous and non-luminous flames is, of course, quite arbitrary, and only corresponds to a rough estimate of the degree of luminosity. Encyclopaedia Britannica, 11th Edition, Volume 10, Slice 4 "Finland" to "Fleury, Andre" 2011-03-20T02:00:30.697Z Another dynamical complication comes from the so-called Tully-Fisher relationship, which describes the relation between a galaxy's luminosity and its rotation velocity: the higher the luminosity, the faster a galaxy rotates.

Rustic Sounds and Other Studies in Literature and Natural History It sounded fairly close at hand, and though no ship was visible, there was just a hint of luminosity in the mist-curtain to indicate the direction of the gun-flashes. Sea-Hounds The green was measured and found to be 53, whilst a measurement of the red and green together gave a luminosity of 96·5 instead of 97.

The Brain It was she who had left behind in the cave this perfumed luminosity, an emanation from her star-body. Toilers of the Sea He studied the line of demarkation, then guessed that the faint luminosity must come from microscopic plant or animal life that clung to the rock underwater. The Caves of Fear All we have to do is to alter the ordinates of the luminosity curve of white light in the proportion to the intensities of the rays before and after passing through the object. Colour Measurement and Mixture 2012-02-27T03:00:13.987Z As the star’s luminosity increases, its rate of nuclear fuel consumption goes up rapidly—just at that point in its life when its fuel supply is beginning to run down.
