Size, atmospheric, and ring constraints on the large Kuiper belt object (55565) Aya from a stellar occultation
Ko Arimatsu, Hidekazu Hanayama, Satoshi Takita +3
We aim to constrain the projected size, geometric albedo, possible atmosphere, and possible ring material of the mid-sized trans-Neptunian object (55565) Aya from the stellar occul…
Opposition effect of comet 28P/Neujmin observed with Subaru Hyper Suprime-Cam
Takafumi Ootsubo, Hideyo Kawakita, Tadafumi Takata +8
We present an observational study of the nucleus of comet 28P/Neujmin at a heliocentric distance exceeding 10 au, where coma contamination is effectively minimized. Observations we…
Detection and characterisation of binary asteroid candidates through stellar occultations
R. Lallemand, J. Desmars, B. Sicardy +256
Binary asteroids provide key access to fundamental parameters of Solar System remnants and planetary formations. However, the current knowledge of binary asteroids remains strongly…
The first detection of an atmosphere on a trans-Neptunian object beyond Pluto
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +4
Trans-Neptunian objects (TNOs) in the outer Solar System are predominantly small, icy worlds long presumed to be atmosphereless except for the largest bodies. Until now, Pluto has…
Moving object detection from multi-depth images with an attention-enhanced CNN
Masato Shibukawa, Fumi Yoshida, Toshifumi Yanagisawa +12
One of the greatest challenges for detecting moving objects in the solar system from wide-field survey data is determining whether a signal indicates a true object or is due to som…
Discovery and dynamics of a Sedna-like object with a perihelion of 66 au
Ying-Tung Chen, Patryk Sofia Lykawka, Yukun Huang +30
Trans-Neptunian objects (TNOs) with large perihelion distances ( au) and semi-major axes ( au) provide insights into the early evolution of the solar system and th…
Characterization of the Deep, Extended Kuiper Belt in the Galactic Disk
Susan D. Benecchi, Simon B. Porter, Anne J. Verbiscer +11
We propose a Roman Space Telescope survey to investigate fundamental properties of the distant solar system in the region of the Kuiper Belt where object characteristics and the si…
An Extremely Deep Rubin Survey to Explore the Extended Kuiper Belt and Identify Objects Observable by New Horizons
JJ Kavelaars, Marc W. Buie, Wesley C. Fraser +22
A proposed Vera C. Rubin Observatory Deep Drilling micro-survey of the Kuiper Belt will investigate key properties of the distant solar system. Utilizing 30 hours of Rubin time acr…
Resonant amplitude distribution of the Hilda asteroids and the free-floating planet flyby scenario
Jian Li, Zhihong Jeff Xia, Hanlun Lei +3
In some recent work, we provided a quantitative explanation for the number asymmetry of Jupiter Trojans by hypothesizing a free-floating planet (FFP) flyby into the Solar System. I…
Candidate Distant Trans-Neptunian Objects Detected by the New Horizons Subaru TNO Survey
Wesley C. Fraser, Simon B. Porter, Lowell Peltier +41
We report the detection of 239 trans-Neptunian Objects discovered through the on-going New Horizons survey for distant minor bodies being performed with the Hyper Suprime-Cam mosai…
Diffraction modelling of a 2023 March 5 stellar occultation by subkilometer-sized asteroid (98943) 2001 CC21
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +31
We present an analysis of a stellar occultation event caused by a near-Earth asteroid (98943) 2001 CC21, an upcoming flyby target in the Hayabusa2 extended mission, on March 5, 202…
A deep analysis for New Horizons' KBO search images
Fumi Yoshida, Toshifumi Yanagisawa, Takashi Ito +8
Observation datasets acquired by the Hyper Suprime-Cam (HSC) on the Subaru Telescope for NASA's New Horizons mission target search were analyzed through a method devised by JAXA. T…
The New Horizons Extended Mission Target: Arrokoth Search and Discovery
Marc W. Buie, John R. Spencer, Simon B. Porter +37
Following the Pluto fly-by of the New Horizons spacecraft, the mission provided a unique opportunity to explore the Kuiper Belt in-situ. The possibility existed to fly-by a Kuiper…
