An optical search for transients lasting a few seconds
Michael W. Richmond, Masaomi Tanaka, Tomoki Morokuma +37
Using a prototype of the Tomo-e Gozen wide-field CMOS mosaic camera, we acquire wide-field optical images at a cadence of 2 Hz and search them for transient sources of duration 1.5…
New constraint on the atmosphere of (50000) Quaoar from a stellar occultation
Ko Arimatsu, Ryou Ohsawa, George L. Hashimoto +35
We report observations of a stellar occultation by the classical Kuiper belt object (50000) Quaoar occurred on 28 June 2019. A single-chord high-cadence (2 Hz) photometry dataset w…
Polarimetric and Photometric Observations of NEAs; (422699) 2000 PD3 and (3200) Phaethon with the 1.6m Pirka Telescope
Ryo Okazaki, Tomohiko Sekiguchi, Masateru Ishiguro +6
We report on optical polarimetric observations of two Apollo type near-Earth asteroids, (422699) 2000 PD3 and (3200) Phaethon, and BVRI photometric observations of 2000 PD3 using t…
Thermal properties of slowly rotating asteroids: Results from a targeted survey
A. Marciniak, V. Alí-Lagoa, T. G. Müller +51
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper into the sub-surface.…
Shape and Rotational Motion Models for Tumbling and Monolithic Asteroid 2012 :High Time Resolution Lightcurve with the Tomo-e Gozen Camera
Seitaro Urakawa, Ryou Ohsawa, Shigeyuki Sako +13
We present visible and near-infrared observations of a near-Earth object (NEO), 2012 . The NEO 2012 approached close to the Earth at a distance of ab…
