WebPoynting-Robertson (PR) drag, and solar wind drag on dust grains trapped in mean motion resonances with the Sun and Jupiter in the restricted (negligible dust mass) three-body problem. We especially examine the evolution of dust grains in the 1:1 reso-nance. As a first step, the Sun and Jupiter are idealized to both be 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. From the perspective of the grain of dust circling a star (panel (a) of the figure), the star's radiation … See more • Differential Doppler effect • Radiation pressure • Yarkovsky effect • Speed of gravity See more The Poynting–Robertson effect is more pronounced for smaller objects.

WebApr 1, 2014 · Solar radiation. Solar wind. Celestial mechanics. 1. Introduction. The force associated with the action of electromagnetic radiation on a moving spherical body (dust particle) is called the Poynting–Robertson (P–R) effect. It is used in astrophysical modelling of orbital evolution of dust grains for many decades. Webpushes it away from the star, a phenomenon called the Poynting-Robertsoneffect since it was first investigated by Poynting [9] using Newtonian gravity and then calculated in the framework of linearized general relativity by Robertson [10]. Successively many authors studied the Poynting-Robertson effect in more concrete situations, starting
WebNov 16, 2024 · 1 What is Poynting-Robertson Drag? Dust grains orbiting a central star are affected by both the gravitational force, as well as photons emitted from the star. The gravitational force is given simply by: where is the gravitational constant, is the mass of the star, is the dust grain’s mass, is the distance from the dust grain to the star, and ...

WebFeb 18, 2001 · The Poynting-Robertson effect causes orbiting particles (on the order of a centimeter in diameter) to slow and fall inward because solar radiation falls slightly more on their leading edge, like raindrops on a speeding car. If the solar system were old, the Poynting-Robertson effect would have caused all particles above a certain size to spiral ... WebIn thermodynamics, the Poynting effect generally refers to the change in the fugacity of a liquid when a non-condensable gas is mixed with the vapor at saturated conditions. …
