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.

TL;DR: In this article, the authors used a large-scale dataset of optical data from more than 100 observers who submittheir optical data to publicly available databases and derived 3D shape models of asteroids together with their rotation periods and orientations of rotation axes.

TL;DR: In this article, a high-angular-resolution imaging survey of 42 large main-belt asteroids with VLT/SPHERE/ZIMPOL was conducted to constrain the formation and evolution of a representative sample of large asteroids.

TL;DR: In this article, the authors present a shape model and bulk density of an interloper in the Eos family, based on the disk-resolved data obtained by the Near InfraRed Camera (Nirc2) mounted on the W.M. Keck II telescope.

TL;DR: The 2009 apparition of comet 107P/Wilson-Harrington was observed with a variety of instruments from six observatories and the main results of this investigation are: (1) 107P was found to be active not only in 1949 but also in 1979, 1992, 2005 and 2009 as discussed by the authors.
