Estimation of the solar constant with simple bolometer

Abstract

There are only a few experiments in astrophysics that can be done in the high school environment. Some astronomical observations leading to the estimate of determining the values of various astronomical parameters (radius of the Earth, the Earth–Moon distance, and others) can be done, but the astrophysical measurements usually require specialised equipment, which is beyond the capabilities of most schools. This frontline describes three simple methods that can be used to estimate the solar constant, which is an important astrophysical parameter.
