The Poynting–Robertson effect, also known as Poynting–Robertson drag, named after John Henry Poynting and Howard P. Robertson, is a process by which solar radiation causes a dust grain orbiting a star to lose angular momentum relative to its orbit around the star. This is related to radiation pressure … See more Robertson considered dust motion in a beam of radiation emanating from a point source. A. W. Guess later considered the problem for a spherical source of radiation and found that for particles far from the source the resultant … See more The effect can be understood in two ways, depending on the reference frame chosen.

L' efecte Poynting-Robertson és un procés pel qual les partícules de pols interestel·lar es mouen lentament en espiral cap al Sol per causa de la radiació solar. Això és degut al fet que el moviment orbital dels grans de pols és contrarestat per la component de la pressió de radiació tangent a aquest moviment.

WebThe Newtonian equations are solved for a particle moving radially outward from the source. Limits for the velocities of high-speed particles resulting from Poynting-Robertson drags are obtained. The fluid equations are discussed briefly in their relation to theoretical treatments of relativistic jets and accretion disks. 9 refs. Authors: WebThe Poynting-Robertson effect will operate to sweep small particles of the solar system into the sun at a cosmically rapid rate. Robertson derived an expression for the times of fall from initially circular orbits. Since, if other parameters are equal, the times are much less for orbits of high eccentricity, tables are given here to enable simple calculation of the times …

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 ...
