Quadratic shift-and-stack for Ground-Based Optical Detection of Faint Cislunar Objects
Qi Li, Yuhui Zhao, Chengxing Zhai +2
Detecting faint objects in cislunar space using ground-based optical telescopes is difficult because of their low brightness, strong lunar background, and complex, nonlinear appare…
Active Asteroid 311P/PANSTARRS: Rotational Instability as the Origin of Multi-tails?
Bin Liu, Xiaodong Liu, Xiaoyu Jia +3
The active asteroid 311P is one of the two targets of a planned Chinese asteroid exploration mission Tianwen-2. During 2013, 311P experienced several mass-loss events and exhibited…
Mid-IR Observations of IRAS, AKARI, WISE/NEOWISE and Subaru for Large Icy Asteroid (704) Interamnia: a New Perspective of Regolith Properties and Water Ice Fraction
Haoxuan Jiang, Jianghui Ji, Liangliang Yu +3
(704) Interamnia is one of the largest asteroids that locates in the outer main-belt region, which may contain a large amount of water ice underneath its surface. We observe this a…
Discovery of Carbon Monoxide in Distant Comet C/2017 K2 (PANSTARRS)
Bin Yang, David Jewitt, Yuhui Zhao +3
Optical observations of the Oort cloud comet C/2017 K2 (PANSTARRS) show that its activity began at large heliocentric distances (up to 35 au), which cannot be explained by either t…
Sublimation as an effective mechanism for flattened lobes of (486958) Arrokoth
Yuhui Zhao, Ladislav Rezac, Yuri Skorov +3
The New Horizons spacecraft's flyby of Kuiper Belt Object (KBO) (486958) Arrokoth revealed a bilobed shape with highly flattened lobes both aligned to its equatorial plane, and a r…
The formation mechanism of 4179 Toutatis' elongated bi-lobed structure in a close Earth encounter scenario
Shoucun Hu, Jianghui Ji, Derek C. Richardson +2
The optical images of near-Earth asteroid 4179 Toutatis acquired by Chang'e-2 spacecraft show that Toutatis has an elongated contact binary configuration, with the contact point lo…
Impact Excitation of a Seismic Pulse and Vibrational Normal Modes on Asteroid Bennu and Associated Slumping of Regolith
Alice C. Quillen, Yuhui Zhao, YuanYuan Chen +3
We consider an impact on an asteroid that is energetic enough to cause resurfacing by seismic reverberation and just below the catastrophic disruption threshold, assuming that seis…
Revisit of rotational dynamics of Asteroid 4179 Toutatis from Chang'e-2's flyby
Yuhui Zhao, Shoucun Hu, Jianghui Ji
This paper presents analysis of the rotational parameters of Toutatis based on the observational results from Chang'e-2's close flyby. The 3-D shape model derived from ground-based…
Chang'e-2 spacecraft observations of asteroid 4179 Toutatis
Jianghui Ji, Yun Jiang, Yuhui Zhao +2
On 13 December 2012, Chang'e-2 completed a successful flyby of the near-Earth asteroid 4179 Toutatis at a closest distance of 770 meters from the asteroid's surface. The observatio…
Orientation and Rotational Parameters of Asteroid 4179 Toutatis: New Insights from Chang'e-2's Close Flyby
Yuhui Zhao, Jianghui Ji, Jiangchuan Huang +4
In this work, we investigate the rotational dynamics of the ginger-shaped near-Earth asteroid 4179 Toutatis, which was closely observed by Chang'e-2 at a distance of m…
The Ginger-shaped Asteroid 4179 Toutatis: New Observations from a Successful Flyby of Chang'e-2
Jiangchuan Huang, Jianghui Ji, Peijian Ye +26
On 13 December 2012, Chang'e-2 conducted a successful flyby of the near-Earth asteroid 4179 Toutatis at a closest distance of 770 120 meters from the asteroid's surface. The…
