Sentence examples for stellar colours from inspiring English sources
A comparison of the V and B magnitudes (see above Stellar colours) yields a B − V colour index, which is related to the colour temperature of the star.
In addition, photometric observations of individual stars from spacecraft and rockets have made possible the measurement of stellar colours over a large range of wavelengths.
One quantitative means of measuring stellar colours involves a comparison of the yellow (visual) magnitude of the star with its magnitude measured through a blue filter.
Since the colours are closely related to surface temperature and therefore to spectral types, equivalent spectral types may be used, but it is stellar colours, not spectral types, that are observed in this instance (see colour-magnitude diagram).
Pollock painted romantic landscapes, intense Western scenes and primitivist mythological dramas before he laid his canvases on the floor, threw and flicked and dripped paint on them, and released his stellar webs of colour into the world.
He pioneered in the use of a coarse grating (for example, a glass plate with closely spaced parallel lines etched into it) in the course of measurement of the separation of double stars; the technique has found widespread use in determining stellar magnitude and colour.
The most important classes of intrinsically variable stars are the following: (1) Pulsating variables stars whose variations in light and colour are thought to arise primarily from stellar pulsations.
The two nebulae - one red and one blue in colour - were both sculpted by powerful stellar winds from extremely hot newborn stars.
These include two previously announced colours, the aquamarine-ish Ocean Depths and the dark matte "Stellar Gray," but also the surprising third options, which adopts the shiny black back of the current all-black Essential, but with the copper titanium antenna band of the Ocean Depths colorway.
In support of this view, he pointed out the presence of jets, condensations, and streamers that are bluish in colour; found around certain galaxies, these are characteristics of an early stage in stellar development.
