The spectral type of the Sun is G2.
For example, the sun is spectral type G2V.
The spectral type of 40 Eridani B was officially described in 1914 by Walter Adams.
For example, our Sun has the spectral type G2.
The star is a red dwarf with spectral type M3V, located 20.3 light-years away from Earth.
It is a main sequence star of the spectral type A5Ivn.
LHS 2090 is a red dwarf star of spectral type M6.5V, located in constellation Cancer at 20.8 light-years from Earth.
T Tauri stars comprise the youngest visible F, G, K and M spectral type stars(<2 M☉).
Sadr has a spectral type of F8Ib.
If a star of the same spectral type is assumed to have equal self-brightness, the distance to the star can be determined by the difference between the brightness and the visible brightness.
Analogs of T Tauri stars in the higher mass range(2- 8 solar masses)- A and B spectral type pre-main sequence stars, are called Herbig Ae/Be stars.
Gliese 581() is a star of spectral type M3V(a red dwarf) about 20 light years away from Earth in the constellation Libra.
A common mnemonic for remembering the spectral type letters is"Oh, Be A Fine Guy/Girl, Kiss Me".
R136b has a transitional spectral type between an O class supergiant and a Wolf-Rayet star, with a mix of absorption and emission lines. Although it shows enhanced helium and nitrogen at its surface, it is still a very young star, still burning hydrogen in its core via the CNO cycle, and still effectively a main sequence object.
Gliese 784 is a red dwarf star of spectral type M0V, located in constellation Telescopium at 20.2 light-years from Earth.
This line is pronounced because both the spectral type and the luminosity depend only on a star's mass, at least to zeroth-order approximation, as long as it is fusing hydrogen at its core- and that is what almost all stars spend most of their"active" lives doing.
LHS 2090 is a red dwarf star of spectral type M6.5V, located in constellation Cancer at 20.8 light-years from Earth.[1].
LHS 3003 is a red dwarf star of spectral type M7.0V, located in constellation Hydra at 20.9 light-years from Earth.
GJ 3737(LHS 337) is a red dwarf star of spectral type M4.5V:, located in constellation Centaurus at 20.8 light-years from Earth.[1].
Gliese 555(HN Librae) is a red dwarf star of spectral type M4.0V, located in constellation Libra at 20.6 light-years from Earth.
GJ 3737(LHS 337) is a red dwarf star of spectral type M4.5V:, located in constellation Centaurus at 20.8 light-years from Earth.
EQ Pegasi is a system of two red dwarf stars of spectral types M3.5V and M4.5V, located in constellation Pegasus at 20 light-years from Earth.
The Sun is a starlocated in the phase called main sequence, with a type spectral G2, which was formed about 5000 million years ago and will remain on the main sequence approximately another 5000 million years.
In contrast, a"color" image made from one spectral band, or an image made from data consisting of non-EM data(e.g. elevation, temperature, tissue type) is a pseudocolor image(see below).
When the first four types of orbitals were described,they were associated with these spectral line types, but there were no other names.
Some species have at least 16 photoreceptor types, which are divided into four classes(their spectral sensitivity is further tuned by colour filters in the retinas), 12 for colour analysis in the different wavelengths(including six which are sensitive to ultraviolet light) and four for analysing polarised light.
