Post-perihelion dust activity and a candidate icy-grain halo in long-period comet C/2023 A3 (Tsuchinshan--ATLAS)
Bin Liu, Xiaoping Zhang, Xiaodong Liu +1
We analyze the post-perihelion coma of the Great Comet of 2024, C/2023 A3 (Tsuchinshan--ATLAS) to characterize dust activity and assess the contribution of sublimating icy grains t…
Dust Activity Evolution and Constraints on Icy Grains in the Interstellar Comet 3I/ATLAS
Bin Liu, Xiaoping Zhang, Xiaodong Liu +1
We present Zwicky Transient Facility observations of the interstellar comet 3I/ATLAS to characterize its dust-activity evolution before and after perihelion. Before perihelion, the…
Interstellar Object 3I/ATLAS Observed from Mars by China's Tianwen-1 Spacecraft
Xin Ren, Wei Yan, Ruining Zhao +20
China's Tianwen-1 Mars orbiter successfully imaged the third interstellar object, 3I/ATLAS, during its close encounter with Mars using the onboard HiRIC CMOS camera. This is China'…
Nucleus and Postperihelion Activity of Interstellar Object 3I/ATLAS Observed by Hubble Space Telescope
Man-To Hui, David Jewitt, Max J. Mutchler +2
We report the detection of the nucleus of interstellar object 3I/ATLAS, using a nucleus extraction technique on Hubble Space Telescope (HST) observations taken between December 202…
Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS
David Jewitt, Man-To Hui, Max Mutchler +2
We present high angular resolution observations of the third known interstellar interloper, 3I/ATLAS, from the Hubble Space Telescope. The object is clearly active at 3.8 au pre-pe…
Great comet C/2023 A3 (Tsuchinshan-ATLAS): dust loss before perihelion
Bin Liu, Man-To Hui, Xiaodong Liu
In this study, the dust loss of comet C/2023 A3 (Tsuchinshan-ATLAS) is investigated through the analysis of archival images. By measuring the surface brightness profile of the coma…
Prediscovery Observations and Orbit of Comet C/2017 K2 (PANSTARRS)
Man-To Hui, David Jewitt, David Clark
We present a study of comet C/2017 K2 (PANSTARRS) using prediscovery archival data taken from 2013 to 2017. Our measurements show that the comet has been marginally increasing in a…
Gone in a Blaze of Glory: the Demise of Comet C/2015 D1 (SOHO)
Man-To Hui, Quan-Zhi Ye, Matthew Knight +2
We present studies of C/2015 D1 (SOHO), the first sunskirting comet ever seen from ground stations over the past half century. The Solar and Heliospheric Observatory (SOHO) witness…
