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:

V-type Near-Earth asteroids: dynamics, close encounters and impacts with terrestrial planets
TL;DR: In this article, the probability of V-type NEAs colliding with Earth, Mars and Venus, as well as the Moon was studied. And the authors found that NEAs can indeed have impacts with all the planets, the Earth in particular, at an average rate of once per 12 Myr.

Yarkovsky effect detection and updated impact hazard assessment for Near-Earth Asteroid (410777) 2009 FD
Alessio Del Vigna,Javier Roa,Davide Farnocchia,Marco Micheli,Dave Tholen,Francesca Guerra,Federica Spoto,Giovanni B. Valsecchi +7 more
TL;DR: In this article, the authors used the Yarkovsky effect to constrain the trajectory of the near-Earth asteroid (410777) 2009 FD and estimated its magnitude from the fit to the optical and radar data collected during the 2019 apparition.

Measuring the Yarkovsky effect with Las Cumbres Observatory
TL;DR: The Las Cumbres Observatory (LCOGT) provides an ideal platform for follow-up and characterization of Solar System objects (e.g. asteroids, Kuiper belt objects (KBOs), comets, and near-Earth objects (NEOs) as well as for the discovery of new objects.

Non-zero Yarkovsky acceleration for near-Earth asteroid (99942) Apophis
Jorge Pérez-Hernández,L. Benet +1 more
TL;DR: In this article , an independent estimation of the Yarkovsky effect based on optical and radar astrometry was presented, which includes observations obtained during 2021 and provided definite collision probability predictions for the close approaches in 2029, 2036, and 2068.

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.
