WebWe present a generalization of the Poynting-Robertson effect to the general relativity, obtaining subsequently, in the Schwarzschild metric, the differential equations which describe the orbital evolution of a small spherical body under the combined action of radiation forces and gravitation. WebDec 2, 2016 · We suggest that the net effect of the photospheric angular momentum loss is similar to Poynting-Robertson "photon braking" on, for example, Sun-orbiting dust. The resultant photospheric torque is readily computed and, over the Sun's lifetime, is found to be comparable to the apparent angular momentum deficit in the near-surface shear layer.

The Poynting effect may refer to two unrelated physical phenomena. Neither should be confused with the Poynting–Robertson effect. All of these effects are named after John Henry Poynting, an English physicist.
WebPoynting-Robertson Effect. The Poynting-Robertson effect is the radiation pressure produced by the Sun’s rays striking the small particles orbiting it, causing them to slow down and spiral towards the gigantic ball of fire. More specifically, this refers to the Sun’s radiation and gravity working together to form an interstellar giant vacuum that sucks in tons and …
