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…
The Western Bulge of 162173 Ryugu Formed as a Result of a Rotationally Driven Deformation Process
Masatoshi Hirabayashi, Eri Tatsumi, Hideaki Miyamoto +26
162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryu…
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…
