à=Ð/Ð8Types of Stars
When you look at the stars you’ll notice that some are white, some are yellow, and some
are red. Stars are classified according to their colors, ranging from electric blue for the
hottest stars to dull red for the coolest stars. Early spectrometers identified emission lines
in the stars’ spectrum for which the spectral (star) classes are named. O type stars are
elecrtic blue and are super giants, burning hot and fast. They are extremely rare. B stars
are bluish in color and cooler, smaller than O stars. A stars are blue-white, F stars are
white to yellow-white, G stars (like our sun and Alpha Centauri A) are yellowish, K stars
(like Alpha Centauri B) are orange, and M stars are the coolest and reddest (red dwarfs
and red giants).
