In diameters of stars, the relative diameters of the two stars in the sirius system were determined. let’s use this value to explore other aspects of this system. this will be done through several steps, each in its own exercise. assume the temperature of the sun is 5800 k, and the temperature of sirius a, the larger star of the binary, is10,000 k. the luminosity of sirius a can be found in appendix j, and is given as about 23 times that of the sun. using the values provided, calculate the radius of sirius a relative to that of the sun.
