Question
Use the information from Table 63.1 along with the StefanBoltzmann law to calculate the radius of the variable star at each phase. When is the star largest? When is it smallest?
Step 1
First, we need to recall the Stefan-Boltzmann law, which states that the luminosity (L) of a star is proportional to its temperature (T) to the fourth power and its radius (R) squared: L = 4 * π * R^2 * σ * T^4 where σ is the Stefan-Boltzmann constant (5.67 x Show more…

Calculate the radius of a star with a luminosity of 4.8x10^31 W and a surface temperature of 3600 K.
Determine the radius of the star Procyon B from the following data: the flux (energy per area) of starlight reaching us from the star is 1.7 10⁻¹²W/m², the distance to the star is 11 light years, and its surface temperature is 6600K. Hint: Find the Luminosity L (the total energy output from the star) by assuming that the star radiates equally in all directions, so that the energy is spread evenly over a sphere whose radius is equal to the distance R to the star: flux = L / (4πR²). Once you have the Luminosity, use the Stefan-Boltzmann law to find the area, and thus the radius, of the star.
Consider the following data on four stars: Which star would have the largest radius? Which star would have the smallest radius? Which star is the most common in our area of the Galaxy? Which star is the least common?
