|
|
<br> In astronomy, there are dwarf stars-red, white, and brown-dwarf novae,
|
|
and even dwarf galaxies. As you might imagine, astronomers use the term dwarf
|
|
when they refer to the smaller objects in any given class. For decades it was
|
|
believed that M stars were the coolest stars in the Galaxy. Some M stars,
|
|
called red dwarfs, make up 70% of the stars in the Galaxy, including our
|
|
nearest known neighbor, Proxima Centauri. However, a new class of objects,
|
|
even cooler than M stars, was recently discovered and given a spectral type
|
|
of L. L-type objects straddle the boundary between red dwarfs and brown
|
|
dwarfs, the latter of which are not massive enough to ignite the nuclear
|
|
processes necessary for it to shine as a star. L-type objects are typically
|
|
very dim stars or brown dwarfs. Even cooler than L-type objects are T-type
|
|
objects. These are mostly brown dwarfs and resemble large, massive,
|
|
Jupiter-like objects, too large to be planets and typically too small to be
|
|
stars. Beyond the T dwarfs are the Y-type objects, which are even more
|
|
dim.(Description from URL) <br><br> Data Reference: The Brown Dwarf Kinematics
