Stars radiate like perfect black bodies with an emissivity of exactly 1. Calculate the rate of heat transfer into space by radiation from a star with a radius equal to 1.19 times the Sun's radius (6.96x108 m) and surface temperature 6,310 K. Give your answer in YW (yotta-Watts, where 1 yotta=1024, a septillion!)
