Demonstrations: H-R Diagram Mobile
As mentioned before, values such as B-V color index and absolute magnitude correspond to stellar properties such as temperature and luminosity. These direct relationships are also seen in the H-R diagram and tables below.
Stars of the same B-V value have the same spectral type and the same temperature T (in units of Kelvin):
|Color Index B-V||Associated Spectral Type||Associated Temperature T (K)|
Stars of the same absolute magnitude (MV) value have the same luminosity L (in units of solar luminosities):
|Absolute Magnitude MV||Associated Luminosity L (LSUN)|
