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…

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…

Asteroid sizes determined with thermophysical model and stellar occultations

A. Choukroun, A. Marciniak, J. Ďurech +165

Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…

New evidence supporting past dust ejections from active asteroid (4015) Wilson-Harrington

Sunho Jin, Masateru Ishiguro, Jooyeon Geem +15

Context. (4015) Wilson-Harrington (hereafter, WH) was discovered as a comet in 1949 but has a dynamical property consistent with that of a near-Earth asteroid. Although there is a…

Photometry and Polarimetry of 2010 XC: Observational Confirmation of E-type Near-Earth Asteroid Pair

Jin Beniyama, Shigeyuki Sako, Katsuhito Ohtsuka +16

Asteroid systems such as binaries and pairs are indicative of physical properties and dynamical histories of the Small Solar System Bodies. Although numerous observational and theo…

Video Observations of Tiny Near-Earth Objects with Tomo-e Gozen

Jin Beniyama, Shigeyuki Sako, Ryou Ohsawa +20

We report the results of video observations of tiny (diameter less than 100 m) near-Earth objects (NEOs) with Tomo-e Gozen on the Kiso 105 cm Schmidt telescope. A rotational period…
