Select the proper units for your inputs and the units you want to get the calculated unknowns in and press solve. In addition, wien's displacement law and stefan's law can both be derived from equation 6.11. Wien's law is written by the equation shown on your screen: The brightness (or luminosity) of a star depends upon its temperature, which in turn determines the star's colour. Please present your answers in a concise table with star name as on column, and star size in terms of the size of the sun in another column.
