Sentences with phrase «spectral lines emitted»

Most light from meteors comes from spectral lines emitted by the elements they contain, so the impacts may be easiest to see though filters which isolate those lines.

That was consistent with a quasar, but dust blocked the definitive quasar signature of spectral lines emitted by gas near the black hole.

Based on the wavelengths of spectral lines emitted by the luminous gas surrounding the black hole, the object is traveling at a speed of about 7.5 million kilometers per hour — a rate that would carry it from Earth to the moon in about 3 minutes.

The metallicity of the gases in the protocluster galaxies was studied using multiple spectral lines emitted from them.

They detected a spectral line emitted by neutral helium gas at a wavelength of 1083 nanometres.

Not exact matches

Indeed, its Lyman - alpha spectrum, i.e. one of the spectral lines of hydrogen it emits, is much narrower and stronger than that of most galaxies, therefore confirming her theoretical predictions.

Yet so far, star formation historians have mostly relied on other indicators to write their histories: light at a particular frequency that is typically emitted when giant clouds collapse, heating up in the process and radiating away that heat in the form of specific spectral lines.

If the atoms are excited, they emit these same wavelengths, hence one can determine precisely which spectral lines belong to which element.

This is due to the fact that most visual light is emitted in one spectral line, the green 5007 Angstrom forbidden line of doubly ionized oxygen, [O III](see our Planetary Nebulae page).

Actually, as for almost all planetary nebulae, most of the visible light is even emitted in one spectral line only, in the green light at 5007 Angstrom (see our planetary nebula description)!

Starting with the surface, each layer attenuates the BB spectrum with the ghg lines and will also emit at the ghg spectral line wavelengths but with a lower power level if the layer temperature is less.
