| Description: Stellar Size and Spectra These spectra are from two stars of the same spectral type (B8) and, hence, the same surface temperature (13,400 K) but different radii and luminosities: (a) the B8 supergiant Rigel (58,000 solar luminosities) in Orion, and (b) the B8 main-sequence star Algol (100 solar luminosities) in Perseus.
