WebThe Poynting-Robertson e ect has been described for the first time by J.H. Poynting (Poynting(1903); Poynting(1904)) who gave a description based on the luminiferous aether theory. The first relativistic description was given by H.P. Robertson (Robertson(1937)). In this section we will present a special rel-ativistic derivation of the ...
