Sentence examples for range of luminosity from inspiring English sources

Many years ago, careful measurements of the average magnitudes and colours of RR Lyrae stars in the globular cluster M3 showed that all these stars fell within a narrow range of luminosity and colour (or surface temperature) or, equivalently, luminosity and radius.

At 11 μm it is not clear what kind of objects are the most luminous because each group spans quite a wide range of luminosity.

What is happening is that, in this range of luminosities, called mesopic, both rods and cones are responding, and, as the rod responses become more pronounced i.e., as darkness increases the rod luminosity scale prevails over that of the cones.

The devices have operated since the early commissioning phase of the accelerator over a broad range of luminosities reaching 1.4×1034 cm−2 s−1 with a peak pileup of 45 events per bunch crossing.

It is likely that there is a range of luminosities for these type IIn supernovae with only the brightest qualifying as a hypernova.

Unfortunately quasars cover a very large range (8 dex) of luminosity making them far from standard.

(2) The temperatures are distributed within narrow range (ΔkT ∼ 0.08 keV) with an average temperature of 0.18 keV in spite of the range of four orders of magnitude in luminosity (1041 45 erg s−1).

The scale of initial luminosity should be in range of 600 1900 mV.

The high-redshift part of the SPIRE GT programme will focus on blank-field surveys with a range of depths and areas optimised to sample the luminosity-redshift plane and characterize the bolometric luminosity density of the universe at high-redshift.

Given the dependence of luminosity on the square of the radius and the fourth power of the temperature (R2T4 of the luminosity expression above), greater luminosity implies larger radius, and such stars are termed giant stars or supergiant stars.

It is called a stepped leader because of its downward-moving "stepped" pulses of luminosity.
