Emission lines in the Balmer series.
They appeared to be faint blue stars with a few unidentified emission lines.
The spectrum shows emission lines of calcium in the H and K bands.
Indeed, even in the Balmer series only the first three emission lines are visible.
Iron quasars show strong emission lines resulting from low ionization iron(FeII), such as IRAS 18508-7815.
They appeared to be faint blue stars with a few unidentified emission lines.
For one, you need a type of molecule with strong emission lines, such as methyl alcohol molecules.
Photographic spectra from 1893 were described as similar to an F5 star,but with a few weak emission lines.
One of the strongest ultraviolet emission lines is the Lyman-alpha line, which comes from hydrogen gas[3].
Emission lines as just described are seen in the spectra of nebulae and the chromosphere, an upper layer in the sun's atmosphere.
These compounds give the comet distinctive blue emission lines- so much so that it is nicknamed“the blue comet”.
Emission lines of hydrogen(mainly of the Lyman series and Balmer series), helium, carbon, magnesium, iron and oxygen are the brightest lines. .
The most prominent features of itsspectrum appeared to be Lyman series emission lines redshifted by nearly 16%(z= 0.158).
The spectrum contains nitrogen and helium emission lines with unusual P Cygni profiles, including"inverse P Cygni" and double-peaked line profiles.
The first star recognized as a B(e)-type star was Gamma Cassiopeiae, observed 1866 by Angelo Secchi,the first star ever observed with emission lines.
It may be observed in broad or forbidden or hot spectral emission lines and is the main source of information about the corona's composition.[2].
A B[e] star, frequently called a B(e)-type star, is a B-type star with distinctive forbidden neutral orlow ionisation emission lines in its spectrum.
It consists of bright emission lines of hydrogen, helium, ionized calcium and other elements that suddenly flash during the complete dimming phase.
A B[e] star, frequently called a B[e]-type star, isa B-type star with distinctive forbidden neutral or low ionisation emission lines in its spectrum.
In 1994,several stars were identified as having broad helium emission lines in their spectra, and some showed narrow hydrogen emission lines.
With these properties, the primary scientific purpose of ASCA is the X-ray spectroscopy of astrophysical plasmas,especially the analysis of discrete features such as emission lines and absorption edges.
These stars frequently also show strong hydrogen emission lines, but this feature is present in a variety of other stars and is not sufficient to classify a B[e] object.
For each quasar, the catalogue listed a name(or names) for each object, its right ascension and declination, V magnitude, B-V color, U-B color,4 z, emission lines present, references, and notes.
The term classicalBe-type star is used for B class stars with emission lines but not having forbidden lines, strong polarisation, or infrared excesses.[1].
This composite spectral type indicates young very massive hydrogen-burning stars that are just starting to convect nitrogen and helium to the surface and develop denser stellar winds so thatthey show the emission lines of a Wolf-Rayet star.
Ultraviolet astronomy is best suited to the study of thermal radiation andspectral emission lines from hot blue stars(OB stars) that are very bright in this wave band.
For this purpose, they targeted emission lines of CO, originating from molecules in dense interstellar clouds, where the formation of new stars is often taking place, and where the temperature of the gas is typically~10K.
The A and B refer to the spectral types of the stars, somewhat hotter than the Sun,and the“e” indicates that emission lines are present in their spectra, due to the glow from the gas around them.
The Marvin web site offers easy access to a wealth of information about each galaxy, including maps of key features such as star formation,stellar motion, emission lines, and dozens of other properties important to astronomers.
