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…
