Pre-perihelion Volatile Evolution of Interstellar Comet 3I/ATLAS Indicating Significant Contribution from Extended Source in the Coma
Juncen Li, Xian Shi, Man-To Hui +1
Interstellar comets provide rare opportunities for probing the diversity of refractory and volatile inventory around other stars. As the second ever interstellar comet, and the thi…
Dynamically New Comet C/2025 D1 (Groeller) with Record Perihelion Distance
Man-To Hui, Robert Weryk, Marco Micheli +5
We studied C/2025 D1 (Groeller), a long-period comet with an unprecedented perihelion distance of 14.1 au, using archival observations. The data reveals that it had been active at…
Pre-perihelion radio observations of comet 12P/Pons-Brooks with Tianma radio telescope
Juncen Li, Xian Shi, Jianchun Shi +7
{The multiple outburst events of comet 12P/Pons-Brooks during its 2024 apparition offer a unique window into highly-active volatile releasing processes not observable during quiesc…
2019 UO: A Transient Trojan of Saturn
Man-To Hui, Paul A. Wiegert, Robert Weryk +5
Saturn has long been the only giant planet in our solar system without any known Trojan members. In this paper, with serendipitous archival observations and refined orbit determina…
Serendipitous Archival Observations of A New Ultra-distant Comet C/2019 E3 (ATLAS)
Man-To Hui, Robert Weryk, Marco Micheli +2
We identified a new ultra-distant comet C/2019 E3 (ATLAS) exhibiting preperihelion cometary activity at heliocentric distances au, making it the fourth member of this…
Perihelion Activity of (3200) Phaethon Is Not Dusty: Evidence from STEREO/COR2 Observations
Man-To Hui
We present an analysis of asteroid (3200) Phaethon using coronagraphic observations from 2008 to 2022 by the COR2 cameras onboard the twin Solar TErrestrial RElations Observatory (…
The Second Earth Trojan 2020 XL
Man-To Hui, Paul A. Wiegert, David J. Tholen +1
The Earth Trojans are co-orbitals librating around the Lagrange points or of the Sun-Earth system. Although many numerical studies suggest that they can maintain their…
