Question
Using the date in the table, calculate the masses of the listed stars using the mass-luminosity relationship equation. Put the values in the first column of a table, following star name. M = (L)^1/3.5 Using Wien's law, calculate the surface temperatures in Kelvin for each of the listed stars. Place the values in a second column of a table. T = 3,000,000/lambda_max Express each of these temperatures in terms of the Sun's temperature by dividing them by 6000. Place the values in a third column of a table. Now calculate the radii of the stars using the stellar radius relationship, and place the values in the fourth column of a table. R = Squareroot L/T4 Given that the Earth orbits about 109 times the Sun's radius away from the Sun, if each of the stars was to replace the Sun, would the Earth be inside the star? Answer this with yes or no in the fifth column of a table.Explanation / Answer
