Lithium Burning
... Lithium is generally present in brown dwarfs and not in low-mass stars ... Therefore, the presence of the lithium line in a candidate brown dwarf's spectrum is a strong indicator that it is indeed substellar ... The use of lithium to distinguish candidate brown dwarfs from low-mass stars is commonly referred to as the lithium test, and was pioneered by Rafael Rebolo and colleagues ...
Oh, Be A Fine Girl And Kiss Me - Extended Spectral Types - Cool Red and Brown Dwarf Classes - Class T: Methane Dwarfs
... Class T dwarfs are cool brown dwarfs with surface temperatures between approximately 700 and 1,300 K ... T ~700–1,300 K, cooler brown dwarfs with methane in the spectrum Examples SIMP 0136 (the brightest T dwarf discovered in northern hemisphere) Examples Epsilon ... probably go on to become main-sequence stars or brown dwarfs of the L and T classes, which are quite invisible to us ...

List Of Least Massive Stars
... This list includes brown dwarfs and red dwarfs ... The name of each brown dwarf has background color brown, and the names of and red dwarfs are against a background of red or orange, depending on whether they are cooler class M or warmer class M ... are not actually these colors.) Although brown dwarfs lack sufficient mass to ignite core hydrogen fusion (75-87 Jupiters, depending on metallicity ...
Sub-brown Dwarf - Failed Brown Dwarfs
... Sub-brown dwarfs are formed in the manner of stars, through the collapse of a gas cloud (perhaps with the help of photo-erosion) but there is no consensus amongst astronomers on whether the formation process ... Free-floating sub-brown dwarfs can be observationally indistinguishable from rogue planets that originally formed around a star and were ejected from orbit, and on the other hand a sub-brown dwarf ...

Famous quotes containing the words dwarfs and/or brown:

    The worth of a State, in the long run, is the worth of the individuals composing it ... a State which dwarfs its men, in order that they may be more docile instruments in its hands even for beneficial purposes—will find that with small men no great thing can really be accomplished.
    John Stuart Mill (1806–1873)

    You sang:
    Me an’ muh baby gonna shine, shine
    Me an’ muh baby gonna shine.
    The strong men keep a-comin’ on
    The strong men git stronger . . .
    —Sterling Allen Brown (b. 1901)
