Sentence examples for surface luminosity from inspiring English sources

OBSERVATIONS of elliptical galaxies show a positive correlation1,2 between total luminosity and core radius, defined as the radius at which surface luminosity becomes half of the central value.

We also present some computations of the photocenter displacement produced by extended objects having a given surface luminosity distribution, corresponding to asteroids obeying different possible scattering laws.

Colorimetric measurements of the model leather samples indicated that after the thermal aging leather is severely darkened by reduction of the surface luminosity (L*), and an increasing of the redness and yellowing has been recorded by increasing the values a* and b*.

The overall luminosity of the cluster steadily decreases with distance from the core, and the core radius is the distance at which the apparent surface luminosity has dropped by half.

The best way to view art is in person, a reproduction in a book is nice, but remember there is more to a painting than the picture represented; tactility of the surface, luminosity, and other subtleties are only accessible in person--it is often the case that the greatness of the work are only apparent in these aspects.

The rate at which the Sun produces energy is equal to the rate at which it emits energy from its surface (its luminosity), which is around 3.8 x 1026 Watts -- this number can be determined from measurements of how bright the Sun appears from Earth as well as its distance from us.

In 2003, using the infrared surface brightness fluctuations (I-SBF) and adjusting for the new period-luminosity value of Freedman et al. 2001 and using a metallicity correction of −0.2 mag dex−1 in (O/H), an estimate of was derived.

Moreover, for stars of a given mass, a fair spread in radius, luminosity, surface temperature, and spectral type may exist.

Conversely, giant stars of very nearly the same radius, surface temperature, and luminosity can have appreciably different masses.

Results from personal unpublished work has provided an average of 72% of usable images for data taken from a small quadcopter with a standard deviation of almost 26%, depending on the type of surface, wind speed, luminosity.

These newly discovered dwarf galaxies have surface brightnesses and luminosities that are an order of magnitude lower than any previously known galaxy.
