TL;DR: In this article, photometric data on 17 binary near-Earth asteroids (15 of them are certain detections, two are probables) were analyzed and characteristic properties of the near Earth asteroid (NEA) binary population were inferred.

TL;DR: In this article, the authors used sparse photometry from selected observatories from the AstDyS database (Asteroids- Dynamic Site), either alone or in combination with dense lightcurves, to determine new asteroid models by the lightcurve inversion method.

TL;DR: The observed distribution appears to be controlled by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect as mentioned in this paper, and the magnitude of the excess of slow rotators is related to the residence time of slowed down asteroids in the excess and the rate of spin rate change outside the excess.

TL;DR: In this paper, the authors used the S-band radar at Arecibo Observatory to observe six new main-belt asteroids (MBAs) and re-observed one, bringing the total number of Tholen M-class asteroids observed with radar to 19.

TL;DR: In this article, the authors compared the observed pole latitude distribution of all asteroids with known convex shape models with the simulated pole latitude distributions and presented 119 new asteroid shape models derived from combined dense and sparse-in-time photometry.
