absolute luminosity造句

• :: : Apparent bightness / apparent luminosity sure does vary with distance, perhaps you were thinking of absolute brightness / absolute luminosity?
• In 2006, the Cepheid absolute luminosity was re-calibrated using Cepheid variables in the galaxy Messier 106 that cover a range of metallicities.
• However, I wasn't trying to compute the absolute luminosity of the star, rather the apparent luminosity, observed at the distance of the planet.
• The absolute luminosity of this latter type is related to properties of its light curve, so that these supernovae can be used to establish the distance to other galaxies.
• In collaboration with Walter Sidney Adams, and in 1914 they discovered that the absolute luminosity of a star was proportional to the relative intensity of the lines in the spectrum.
• I added the following to Barnard's star yesterday : It has a " visual luminosity just 4 / 10000 of solar, corresponding to a bolometric or absolute luminosity of 3.46 / 1000 . " This is based on this and this paper within it.
• In collaboration with Gary DaCosta and Michael David Crawford, Dr . Mould prepared Hertzsprung Russell Diagrams of Large Magellanic Cloud and Small Magellanic Cloud Globular Clusters to determine their age, with the resulting Standard Candle being the brightest star in each cluster, with that star's absolute luminosity being derivable from its distance, with the B-R Color of the brightest cluster's star being used to determine the ages of more distant clusters by the colors of their brightest stars.
