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…
Non-Gravitational Acceleration of the Active Asteroids
Man-To Hui, David Jewitt
Comets can exhibit non-gravitational accelerations caused by recoil forces due to anisotropic mass loss. So might active asteroids. We present an astrometric investigation of 18 ac…
Resurrection of (3200) Phaethon in 2016
Man-To Hui, Jing Li
We present a study of the active asteroid (3200) Phaethon in the 2016 apparition using the STEREO spacecraft and compare the results with data from the previous two perihelia in 20…
Constraints on Comet 332P/Ikeya-Murakami
Man-To Hui, Quan-Zhi Ye, Paul Wiegert
Encke-type comet 332P/Ikeya-Murakami is experiencing cascading fragmentation events during its 2016 apparition. It is likely the first splitting Encke-type comet ever being observe…
Fragmentation Kinematics in Comet 332P/Ikeya-Murakami
David Jewitt, Max Mutchler, Harold Weaver +9
We present initial time-resolved observations of the split comet 332P/Ikeya-Murakami taken using the Hubble Space Telescope. Our images reveal a dust-bathed cluster of fragments re…
