Absolute Magnitudes of Asteroids and a Revision of Asteroid Albedo Estimates from WISE Thermal Observations
TL;DR: In this paper, the authors obtained estimates of the Johnson V absolute magnitude (H ) and slope parameters (G ) for 583 main-belt and near-Earth asteroids observed at Ondřejov and Table Mountain Observatory from 1978 to 2011.

TL;DR: In this paper, the authors studied a sample of 93 asteroid pairs, i.e., pairs of genetically related asteroids that are on highly similar heliocentric orbits, and derived the absolute magnitude differences of the studied asteroid pairs that provided their mass ratios q.

Spinup and Disruption of Interstellar Asteroids by Mechanical Torques, and Implications for 1I/2017 U1 (‘Oumuamua)
TL;DR: In this paper, the rotational dynamics of irregular shapes moving through the interstellar gas were studied and it was shown that regular mechanical torques resulting from the bombardment of gas flow on the irregular body could be important for the dynamics and destruction of ISAs.

The Long-Term Dynamical Behavior of Short-Period Comets
TL;DR: In this paper, the authors developed and tested a new computer code to follow the long-term dynamical evolution of a swarm of test particles in the solar system and found that the Tisserand parameter, T, does not vary substantially for most comets.
The long-term dynamical behavior of short-period comets
TL;DR: In this article, it is shown that the anomalous concentration of the argument of perihelion of the Jupiter-family comets near 0 and 180 deg is a direct result of their aphelion distance being close to 5.2AU and the comet being recently perturbed onto a Jupiter- family orbit.
