Abstract:
Currently, the science of astronomy for the study of origins and evolutions is advancing both theoretically and observationally. However, there are a number of works
for further developments. For example, the data extracted on earth is highly extinct
due to stellar winds, background radiations and planetary atmospheres. In this work
we did on the effect of atmospheric extinction on astronomical photometry and spectroscopy analytically. The appropriate radiative transfer and plank’s equation was
being derived from black body radiation equation were a series of integral homology
transformation were used. The method we applied is the Plancks radiation law where
we did assume an exponential atmosphere that obeys the Beer-Bouguet-Lambert law
of the optical depth equation. The results are in agreement with observational works
and the standard theories. However, this work is limited to high approximations.
