Used in astronomy to determine the magnitude and spectral class of a star.

From this process, a map with m spectral classes is obtained.

Astronomers are not sure what its spectral class is.

There is some uncertainty as to its spectral class.

P2 also contains a compact disk of hot, spectral class A stars.

This star belongs to the spectral class K0 and has apparent magnitude +3.8.

Also keep your eye out for unusual spectral classes.

Does he care about their size and brightness and spectral classes?

This suggests that their planet orbited a star of the spectral class K-1.

The spectral class of the star is Am.

Meteorites can also be compared to spectral classes of asteroids.

This measurement does not rule out a low mass stellar companion of spectral class M7.

The stars of this spectral class are blue giants, hot, unstable, remaining on the main sequence only a few million years.

The primary has an absolute magnitude of 2.6 and is of spectral class F0.

The secondary may itself have an orbiting stellar companion of spectral class F8:.

The primary is a giant star of spectral class G8 and apparent magnitude of 4.4.

Its age is estimated at 10 million years, as its five hottest stars are all giants of spectral class B0.

It takes hundreds of millions of years at least for a stable star to move from one spectral class to another."

The primary, with spectral class A7, appears white and the secondary appears bluish.
