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:

TL;DR: In this paper, the authors conducted a community-led global planetary defense exercise with support from the NASA Planetary Defense Coordination Office to test the preparedness to respond to a potential NEO impact threat, and the target of their exercise was 2012 TC4, the ~10" diameter asteroid that made a close pass by the Earth on 2017 October 12 at a distance of about 50,000 km.

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: In this paper, 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.

Asteroids 87887 – 415992: the youngest known asteroid pair?
TL;DR: In this paper, the authors search for candidate very young asteroid pairs in the current catalog of asteroid orbits and select the most promising case of the small asteroids (87887) 2000 SS286 and (415992) 2002 AT49.

An Investigation of the Ranges of Validity of Asteroid Thermal Models for Near-Earth Asteroid Observations
TL;DR: In this paper, the authors investigate the applicability of the NEATM and the FRM to thermal-infrared observations of Near-Earth Objects using synthetic asteroids with properties based on the real Near Earth Asteroid (NEA) population.

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.
