We present a study of Jovian Trojan objects detected serendipitously during the course of a sky survey conducted at the University of Hawaii 2.2 m telescope. We used a 8192 × 8192 pixel charge-coupled device (CCD) mosaic to observe 20 deg2 at locations spread over the L4 Lagrangian swarm and reached a limiting magnitude V = 22.5 (50% of maximum detection efficiency). Ninety-three Jovian Trojans were detected with radii 2 km ≤ r ≤ 20 km (assumed visual albedo 0.04). Their differential magnitude… Expand

Size Distribution of Faint Jovian L4 Trojan Asteroids
We detected 51 faint Jovian Trojan asteroids in the L4 Lagrangian swarm in survey observations near opposition and the ecliptic using a wide-field mosaicked CCD camera on the 8.2 m Subaru Telescope.Expand
Small Jupiter Trojans Survey with the Subaru/Hyper Suprime-Cam
We observed the L4 Jupiter Trojans (JTs) swarm using the Hyper Suprime-Cam attached to the 8.2 m Subaru Telescope on 2015 March 30 (UT). The survey covered ~26 deg2 of sky area near the oppositionExpand
The Albedo Distribution of Jovian Trojan Asteroids
We present radiometrically derived V-band geometric albedos and effective radii for 32 Jovian Trojan asteroids, using near-simultaneous mid-infrared and visible observations. We sampled the large endExpand
The properties of Jovian Trojan asteroids listed in SDSS Moving Object Catalogue 3
We analyse 1187 observations of about 860 unique candidate Jovian Trojan asteroids listed in the 3rd release of the Sloan Digital Sky Survey (SDSS) Moving Object Catalogue. The sample is complete atExpand
Albedos of Small Jovian Trojans
We present thermal observations of 44 Jovian Trojan asteroids with diameters D ranging from 5 to 24 km. All objects were observed at a wavelength of 24 μm with the Spitzer Space Telescope.Expand
WISE/NEOWISE Observations of the Jovian Trojans: Preliminary Results
We present the preliminary analysis of over 1739 known and 349 candidate Jovian Trojans observed by the NEOWISE component of the Wide-field Infrared Survey Explorer (WISE). With this survey theExpand
A comparative study of size frequency distributions of Jupiter Trojans, Hildas and main belt asteroids: A clue to planet migration history
Abstract Since 2002, we have obtained size frequency distributions (SFDs) of main belt asteroids (MBAs), Hildas, and Jupiter Trojans (JTs) by using the 8.2-m Subaru Telescope equipped with theExpand
The Size Distribution of the Neptune Trojans and the Missing Intermediate Sized Planetesimals
We present an ultra-deep survey for Neptune Trojans using the Subaru 8.2-m and Magellan 6.5-m telescopes. The survey reached a 50% detection efficiency in the R-band at 25.7 magnitudes and covered 49Expand
A Comparative Study of Size Distributions for Small L4 and L5 Jovian Trojans
We examined the size distributions of small L4 and L5 Jovian Trojan asteroids detected in the Subaru main belt asteroid survey (SMBAS). This was the first attempt to make a comparison of the sizeExpand
The color-magnitude distribution of small Jupiter Trojans
We present an analysis of survey observations targeting the leading L4 Jupiter Trojan cloud near opposition using the wide-field Suprime-Cam CCD camera on the 8.2 m Subaru Telescope. The surveyExpand
