different frequencies of light as they whip in and out of view, causing Epsilon Ursae Majoris to have very strange spectral lines that fluctuate over a period of 5.1 days.
giving a simple expression for the hydrogen energy levels and thus the frequencies of the hydrogen spectral lines and fully reproduced the Bohr model and went beyond it.
physical properties of astronomical objects as well as measuring object velocities from the Doppler shift of spectral lines.
sulfate.[31] They observed spectral lines which they presumed to be of eka-caesium.
Analysis of these spectral lines also can provide velocity, temperature and density data,
Spectra taken of these distant galaxies showed a red shift in their spectral lines presumably caused by the Doppler effect, thus indicating that these galaxies were moving away from the Earth.
John Bahcall, Wal Sargent, and Maarten Schmidt measure the fine-structure splitting of spectral lines in 3C191 and thereby show that the fine-structure constant does not vary significantly with time.
In addition, stars may be classified by the luminosity effects found in their spectral lines, which correspond to their spatial size and is determined by the surface gravity.
This system uses certain diagnostic spectral lines to estimate the surface gravity of a star, hence determining its size relative to its mass.
particular radiation is determined, it can be compared to the extremely acute comb spectral lines, until one is found that"fits".
Canum Venaticorum type variable, a chemically peculiar star with a strong magnetic field and strong strontium, silicon, or chromium spectral lines.
Spectral lines also depend on the physical conditions of the gas, so they are widely
they noticed that stars had very different hydrogen spectral lines strengths, and so they classified stars based on the strength of the hydrogen balmer series lines from A(strongest) to Q(weakest).
While the spectral lines strongly indicate that the star is of spectral type F2V-IV, previous analyses have
By means of these quantized orbits, he accurately explained the spectral lines of the hydrogen atom.[42] However, Bohr's model failed to
planets, and other stellar features through the spectral lines, as well as observing the motion and expansion of the universe,
type Ic supernovae that have broad spectral lines corresponding to high-velocity outflows are thought to be strongly associated with GRBs.
The same effect has been observed for other spectral lines such as the Ly-α hydrogen line and the C III(λ 1909) line of twice ionised carbon.[1] It has also been found for spectral lines in the infrared range, e.g. in several Seyfert galaxies.[2].
There are spectrometers to determine the chemical composition of celestial phenomena from their spectral lines, and two kinds of imaging sensor- bolometers, which determine the intensity of incoming radiation from the change in their material's electrical resistance as they heat up;
