Albedo heterogeneity on the surface of (1943) Anteros [PDF]

open access: yes, 2009
We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the University of Hawaii's 2.2 m telescope.

Asteroid Photometric Phase Functions From Bayesian Lightcurve Inversion

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Photometry is an important tool for characterizing the physical properties of asteroids. An asteroid’s photometric lightcurve and phase curve refer to the variation of the asteroid’s disk-integrated brightness in time and in phase angle (the Sun-asteroid-

Scaling slowly rotating asteroids with stellar occultations

open access: yesAstronomy & Astrophysics, 2023
Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models because of selection bias. This bias is skewing our overall understanding of the spins, shapes, and sizes of asteroids, as well as of their other properties. Also, diameter determinations for large (

Preliminary refinement of rotation parameters of asteroids based on photogrammetric processing of on-orbit remote sensing images [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
In recent years, asteroid exploration has become an important research direction in the field of deep space exploration. The weak gravitational environment of asteroids, as well as their complex topographic, geomorphic, and dynamic characteristics, pose ...

Asteroid lightcurves from the Palomar Transient Factory survey: Rotation periods and phase functions from sparse photometry [PDF]

open access: yes, 2015
We fit 54,296 sparsely-sampled asteroid lightcurves in the Palomar Transient Factory to a combined rotation plus phase-function model. Each lightcurve consists of 20+ observations acquired in a single opposition.

Deflecting small asteroids using laser ablation : Deep space navigation and asteroid orbit control for LightTouch2 Mission [PDF]

open access: yes, 2013
This paper presents a low-cost, low mass, mission design to successfully intercept and deflect a small and faint, 4 m in diameter asteroid. Intended to be launched after 2025, the laser-ablating mission, LightTouch2 will be used to deflect the orbit of ...

A New Large Super-Fast Rotator: (335433) 2005 UW163 [PDF]

open access: yes, 2014
Asteroids of size larger than 150 m generally do not have rotation periods smaller than 2.2 hours. This spin cutoff is believed to be due to the gravitationally bound rubble-pile structures of the asteroids.

The binary near-Earth asteroid (175706) 1996 FG3 - An observational constraint on its orbital evolution [PDF]

open access: yes, 2014
Using our photometric observations taken between 1996 and 2013 and other published data, we derived properties of the binary near-Earth asteroid (175706) 1996 FG3 including new measurements constraining evolution of the mutual orbit with potential ...
