Stars as massive as this will have luminosities about one million times greater than that of the Sun. |
Of great statistical interest is the relationship between the luminosities of the stars and their frequency of occurrence. |
This shows the method which is adopted, of deducing luminosities from intensities. |
Stars, however, come in a staggering range of luminosities, spanning ten orders of magnitude ten powers of ten. |
Visual galactic luminosities show similar spreads among the three types, but the irregulars tend to be less luminous. |
Several of the stellar class of white dwarf stars, which have low luminosities and high densities, also are among the brightest stars. |
