Newman has extensive theatre experience, including Loveplay by Moira Buffini; Luminosity by Nick Stafford; Night of the Soul by David Farr and The Big Lie by Anthony Neilson, all for the RSC, as well as The Censor and The Lying Kind, both by Anthony Neilson, for the Royal Court Theatre, London.

Danjon scale

The Danjon Scale of lunar eclipse brightness is a five-point scale useful for measuring the appearance and luminosity of the Moon during a lunar eclipse.

Francesco Nicolosi

The authoritative Corriere della Sera critic and musicologist Paolo Isotta wrote of Nicolosi on the occasion of the recent recording of two rare concerts of Paisiello: (...) listening to him playing is enough to remind us that no one today can match his luminosity of sound, his ability to draw out the song-like legato qualities of a keyboard instrument ... he has acquired a reputation as one of our greatest living pianists ...

Giovanni Serodine

His style has the loose brushstroke and luminosity of some of the northern Caravaggisti, such as Lys, Strozzi, and Fetti, who were active in Venice; however, some of Serodine's canvases show a provincial eccentricity, for example Coronation of the Virgin in Ascona.

K-type main-sequence star

K dwarf, is a main-sequence (hydrogen-burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars and yellow G-type main-sequence stars.

Maarten Schmidt

While its star-like appearance suggested it was relatively nearby, the spectrum of 3C 273 proved to have what was at the time a high redshift of 0.158, showing that it lay far beyond the Milky Way, and thus possessed an extraordinarily high luminosity.

Main sequence

Since the luminosity gives the amount of energy radiated per unit time, the total life span can be estimated, to first approximation, as the total energy produced divided by the star's luminosity.

Multifractal system

They include fully developed turbulence, stock market time series, real world scenes, the Sun’s magnetic field time series, heartbeat dynamics, human gait, and natural luminosity time series.

Prince of Burma

As the rubies from Mogok have formed in marble surroundings with a low content of iron, they display a particularly intense luminosity, which sets off the natural carmine red of the rubies.

Sagittarius A*

The comparatively small mass of this black hole, along with the low luminosity of the radio and infrared emission lines, imply that the Milky Way is not a Seyfert galaxy.

Stellar isochrone

They contract and dim along the Hayashi track, decreasing in luminosity but staying at roughly the same temperature, until reaching the main sequence directly or by passing through the Henyey track.

TVLM513-46546

Assuming a stellar luminosity of 0.042 percent that of Sun, the habitable zone where an Earth-like planet may retain liquid water at comfortable temperatures would be located within 0.02 Astronomical Units (roughly 10 times the distance of the Moon from Earth).
