单词	spectral type
释义	spectral type (also spectral class) noun The group in which a star is classified according to its spectrum, especially using the Harvard classification.Such an association is named ‘OB’ because these stars have O and B spectral types.... Fomalhaut is only moderately Sun-like; its spectral class is A 3 Va, it's 1.7 times the Sun's diameter, has 2.3 times its mass, and is 13 times as bright. Suppose we wanted to find one like the Sun: say, between spectral types F5 and K5, not part of a double or multiple system, and at least a billion years old (to let things settle down a bit).
