@article{Oh2011FiniteSE, title={Finite size effects on the Poynting-Robertson effect: a fully general relativistic treatment}, author={Jae Sok Oh and Hongsu Kim and Hyung-Mok Lee}, journal={New Astronomy}, year={2011}, volume={16}, pages={183-186} }

Abstract Even since the first discovery of Poynting and Robertson, the radiation source has been treated as merely a point. Even in a very few studies where the size of the source has been taken into account, the treatment of the problem remained largely non-relativistic. In the present work, we address the issue of the finite size effects on the Poynting–Robertson effect in a fully relativistic manner for the first time. As a result, the emergence and the characteristic of the critical point…
