Part A The chart below lists six stars. Research the luminosity, distance from Earth, and surface temperature of
each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances
should be given in light years and temperatures given in Kelvin, Luminosity (L) is how bright something is
in human eyesight. As you conduct your research, look for the luminosity of each star relative to the Sun
(Therefore, the luminosity of the Sun is 1), If your sources give a fraction for luminosity, convert the
fraction into a decimal
number. Use your research to complete the chart,
