Sentences with phrase «luminosity =»

Values are expressed relative to pre-industrial conditions (CO2 = 280 ppm; solar luminosity = 342 W / m2).

Values are expressed relative to pre-industrial conditions (CO2 = 280 ppm; solar luminosity = 342 W / m2); a reference line of zero is given for clarity.

The larger a star (i.e., more massive) is, the more luminous it is (luminosity = mass3).

Because the luminosity = the energy / time, the apparent brightness will be reduced enough by the expansion to make the sky dark.

Not exact matches

RR - Lyrae have the same time - averaged luminosity (about 49 solar luminosities or an absolute magnitude MV = +0.6).

For the inner few kiloparsecs of the elliptical galaxies, the velocity dispersion = 220 × (L / L *) 0.25, where L * is a characteristic galaxy luminosity (around 10 billion solar luminosities).

The Tully - Fisher relation for the infrared luminosity is: circular velocity = 220 × (L / L *) 0.22.

This is the relationship between luminosity (L), radius (R) and temperature (T): L = (7.125 x 10 - 7) R2T4 where the units are defined as L - watts, R - meters and T - degrees Kelvin
