... A spectroscopic binary is a system detected from the periodic shift of its spectral lines. This shift is caused by the Doppler effect as the orbits of the stars carry them alternately toward and away from Earth. An eclipsing binary is a system whose orbits are viewed nearly edge-on from Earth, so th ...

... There is a relationship between the temperatures of stars and how bright they are (luminosity). In general, the hotter a star the brighter. This is not always true though. For example, Polaris is the same temperature as our Sun, but is around 4000X brighter. This difference is due to the mass and si ...

Characteristics of Main Sequence Stars Main-sequence stars obey several relations (which are mostly predictable from homology). • Main sequence stars obey a mass-luminosity relation, with L ∝ Mη . The slope η changes slightly over the range of masses; between 1 and 10M¯ , η ≈ 3.88. The relation flat ...
