TLDR
In this article, the Yarkovsky effect among near Earth asteroids (NEAs) was investigated by measuring the YARKovsky-related orbital drift from the orbital fit using a high precision dynamical model, including the Newtonian attraction of 16 massive asteroids and the planetary relativistic terms.About:

Asteroid 1566 Icarus's size, shape, orbit, and Yarkovsky drift from radar observations
Adam H. Greenberg,Jean-Luc Margot,Ashok Kumar Verma,Patrick A. Taylor,Shantanu P. Naidu,Marina Brozovic,Lance A. M. Benner +6 more
TL;DR: Greenberg et al. as discussed by the authors used radar observations of 1566 Icarus obtained at the Arecibo Observatory and the DSS-14 antenna at Goldstone to show that the asteroid is a moderately flattened spheroid with an equivalent diameter of 1.44 km with 18% uncertainties.

Theory and Experiment in Gravitational Physics
TL;DR: In this paper, the authors provide a complete treatment of techniques for analyzing gravitation theory and experience, taking into account the Dicke framework, basic criteria for the viability of a gravitation theories, experimental tests of the Einstein equivalence principle, Schiff's conjecture, and a model theory devised by Lightman and Lee (1973).

THE YARKOVSKY AND YORP EFFECTS: Implications for Asteroid Dynamics
TL;DR: The Yarkovsky and YORP effects are thermal radiation forces and torques that cause small objects to undergo semimajor axis drift and spin vector modifications, respectively, as a function of their spin, orbit, and material properties as discussed by the authors.
Application of photometric models to asteroids.
TL;DR: In this paper, the brightness of a rough and porous surface is parameterized in terms of the optical properties of individual particles, by shadowing between particles, and by the way in which light is scattered among collections of particles.
