Journal ArticleDOI
A study of asteroid pole-latitude distribution based on an extended set of shape models derived by the lightcurve inversion method
Josef Hanus,Josef Ďurech,Miroslav Brož,Brian D. Warner,Frederick Pilcher,Robert D. Stephens,Julian Oey,L. Bernasconi,S. Casulli,Raoul Behrend,David Polishook,Tomáš Henych,M. Lehký,Fumi Yoshida,Takashi Ito +14 more
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.
Journal ArticleDOI

Pray,David Higgins,Julian Oey,Adrian Galad,Štefan Gajdoš,Leonard Kornoš,Jozef Vilagi,Marek Husárik,Yu. N. Krugly,Vasilij G. Shevchenko,Vasilij G. Chiorny,N. Gaftonyuk,Walter R.

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.
Journal ArticleDOI

TL;DR: In this paper, the authors used the theory of asteroid nutational damping by Breiter et al. and found that slowly tumbling asteroids predominate in the spin rate-size range where their estimated damping times are greater than about 0.2 Gyr.
Journal ArticleDOI
Asteroids’ physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution

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, Sharma et al. collected data on rotations and elongations of 46 secondaries of binary and triple systems among near Earth, Mars-crossing and small main belt asteroids.
