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…
