Graduated with BSc in Engineering Physics in 1953, then well after retirement, an MSc in Astronomy in 2009. I have a deep interest in the physical sciences and find the questions in this site to be a great learning experience.

comment Temperature on the surface of the sun calculated with the Stefan-Boltzmann-rule
I want you to be aware that my answer was an attempt to answer the question of how Sherlock might have determined the Sun's temperature using your R and D factors. It no way is a valid use of the formula I posted. It was simply a trick using a valid formula. But it answered your question.

Peter, effective temperature is basically the average temperature of a body orbiting the Sun. Sub-solar temperatures occur at the Sun's zenith for a body.
