He founded a major school on atomic and molecular spectral analysis.

Indeed, this star is the prototype for white dwarfs of this class.

V343 Carinae is a blue white B type giant with a mean apparent magnitude of 4.31.

Delta Crucis (δ Cru, δ Crucis) is a star in the southern circumpolar constellation of Crux.

The background radiation is simply too static to be able to be seen under the normal spectral analysis.

The hotter component is of the spectral type F or G and luminosity class V or IV.

HD 107146 is a star in the constellation Coma Berenices that is located about 90 light years from Earth.

Either component is of the spectral type G through K and luminosity class II through IV.

Sigma Boötis (σ Boo, σ Boötis) is a star in the constellation Boötes.

However, the reason for the existence of such chemically peculiar, spectral class A0 F0 stars remains unclear.

It is a main sequence star with a stellar classification of B6 Vep, but is about 3,150 times more luminous than the Sun.

It is a yellow white F type subgiant with an apparent magnitude of 3.99 and is approximately 52.9 light years from Earth.

Sigma Octantis is approximately 270 light years from Earth, and is classified as a giant, with a spectral type of F0 III.

It has a stellar classification of K0 IIIb, with 2.5 times the mass of the Sun and 10 times the Sun's radius.

That is, the hydrogen spectral lines of these stars are weaker than normal for a star of stellar class B, while the lines of helium and carbon are stronger.

This mass range is typical of a B type main sequence star, suggesting the star belong to stellar class B when it was on the main sequence.

In 1893, German physicist Wilhelm Wien quantified the relationship between blackbody temperature and the wavelength of the spectral peak with the following equation

Next example is analyzing the spectral emissions of stars and trying to find clusters of stars in dissimilar types that may be of interest to astronomers.

It is a yellow white F type bright giant with an apparent magnitude of 4.47 and is approximately 454 light years from Earth.

Alpha Camelopardalis (Alpha Cam, α Camelopardalis, α Cam) is a star in the constellation Camelopardalis, with an apparent visual magnitude of 4.301.

16 Lyrae (16 Lyr) is a 5th magnitude star in the constellation Lyra, approximately 128 light years away from Earth.

The star has a visual companion, CCDM J22313 5017B, of spectral type A and apparent visual magnitude 11.8, approximately 36 arcseconds away.

Cha Halpha 1, an M8 object in the Chamaeleon I dark cloud, is determined to be an X ray source, similar to convective late type stars.

It is a spectral type G star, about 1.16 solar masses and radii greater than our Sun, and only 200 Kelvins hotter.

In Chinese, (), meaning Celestial Ford , refers to an asterism consisting of γ Cygni, δ Cygni, 30 Cygni, α Cygni, ν Cygni, τ Cygni, υ Cygni, ζ Cygni and ε Cygni.

Flare Star SystemsThe hotter component is of the spectral type dKe or dMe, where the emission refers to strong Ca II H and K.V. V471 Tau Type Systems The hotter component is a white dwarf.

There are also classes of chemically peculiar cool stars (that is, stars with spectral type G or later), but these stars are typically not main sequence stars.
