Using this period-luminosity relation, in 1913 the distance to the SMC was first estimated by Ejnar Hertzsprung. WikiMatrix The same type of diagram is still used today as a means of showing the stars in clusters without having to initially know their distance and luminosity. LASER-wikipedia...

The non-linear character of Born-Infeld electrodynamics modifies the relation between the energy flux and the distance to the source, which gains a new dependence on the redshift that is governed by the background field. We compute the luminosity distance as a function of the redshift and ...

Its high luminosity and large distance (about 1,500 light years) give it an apparent visible magnitude of 5.1. WikiMatrix At O2–O4, the distinction between main sequence and supergiant stars is narrow and may not even represent true luminosity or evolutionary differences. WikiMatrix An except...
