The main star, θ¹ Eridani,is of spectral class A4 with a +3.2 apparent magnitude.
As GD 165B is the prototype of the L dwarfs, Gliese 229B is the prototype of a second new spectral class, the T dwarfs.
They are classified as spectral Class 0 protostars.
It allows you, for example, to determine the distances between stars, to view them from any point of view, orto filter your view by spectral class and luminosity.(doc).
Its companion star, θ² Eridani, is of spectral class A1 with an apparent magnitude of +4.3.
A white giant of spectral class A7III, it is an aging star that has used up the hydrogen fuel at its core and has expanded and cooled after moving off the main sequence.
Its apparent magnitude is +4.25 and it belongs to the spectral class K4.5III-IIIb.
It is a yellow-white dwarf(spectral class F8 V), a type of star hotter and more luminous than our Sun.
The reason for the existence of such chemically peculiar, spectral class A0-F0 stars remains unclear.
It has been given a spectral class C7,2, indicating a relatively cool carbon star with only modest C2 band strength.
Young associations will contain 10-100 massive stars of spectral class O and B, and are known as OB associations.
Very hot stars of the spectral class O or B emit very energetic radiation, especially ultraviolet radiation, which is able to ionize the neutral hydrogen(H I) of the surrounding interstellar medium, so that hydrogen atoms lose their single electrons.
Alpha Vulpeculae is a red giant of spectral class M1 and has apparent magnitude +4.4.
However, spectroscopic analyses showed that these largest members werein fact interlopers in their own family, having a different spectral class from the bulk of the members.
The core star is believed to be of spectral class B0 and has 12,200 times the solar luminosity.
Such pinwheels have been observed in the Quintuplet Cluster The archetype of such a colliding-wind binary system is WR 140(HD 193793), which consists of a 20 solar mass(M☉)Wolf-Rayet star orbiting about a 50 M☉, spectral class O4-5 main sequence star every 7.9 years.
The giant star Antares, which is very red(spectral class M1), is surrounded by a large, red reflection nebula.
Delta Cygni A, is a blue-white giant star of spectral class B9, with a temperature of 10,500 K. It is nearing the end of its main-sequence life stage with a luminosity 155 times that of the Sun, a radius of 5.13 solar radii, and a mass approximately 2.93 solar masses.
CFBDSIR 1458+10 bolometric luminosity estimates In Liu et al.(2011) CFBDSIR 1458+10 B was assigned to the spectral class>T10, it was proposed that CFBDSIR 1458+10 B may be a member of the Y spectral class of brown dwarfs.
Finally, the introduction of the spectral class O2 and the refinement of slash star classifications led to it being tagged as O2 If.
The color indexes vary with the star's brightness, but the spectral class of BM Andromedae does not change with the decrease of luminosity.
