Then, what is a star's luminosity class?
Luminosity classes are labeled with Roman numerals from I to V: I are supergiant stars, II are bright giants, III are ordinary giants, IV are subgiants, and V are ordinary main sequence stars. The complete spectral classification for a star is then given by specifying both the spectral class and the luminosity class.
Likewise, what is the spectral type and luminosity class of the sun? 1 L☉
Additionally, what is a star's luminosity quizlet?
luminosity- The luminosity of a star is the amount of light it emits from its surface. apparent brightness-how bright the star appears to a detector here on Earth. The difference between luminosity and apparent brightness depends on distance.
What does g2v mean?
In Sun. … Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class—of surface temperature about 5,800 kelvins (K)—and the V representing a main sequence, or dwarf, star, the typical star for this temperature class. (G stars are so called because of…
