Abstract:
We present an asteroidal catalog from the mid-infrared wavelength
region using the slow-scan observation mode obtained by the Infrared
Camera (IRC) on-board the Japanese infrared satellite AKARI. An
archive of IRC slow-scan observations comprising about 1000 images was
used to search for serendipitous encounters of known asteroids. We
have determined the geometric albedos and diameters for 88 main-belt
asteroids, including two asteroids in the Hilda region, and compared
these, where possible, with previously published values. Approximately
one-third of the acquired data reflects new asteroidal information.
Some bodies classified as C or D-type with high albedo were also
identified in the catalog.
Description:
The Asteroid Catalog using AKARI IRC Slow-Scan Observations (AcuA-ISS)
is the first asteroid catalogue produced based on the AKARI IRC
Slow-Scan Observations. The catalogue provides the size and albedo of
88 asteroids.
AKARI is the Japanese infrared astronomical satellite operated in
2006-2011. AKARI has carried out an all-sky survey in the mid- and
far-infrared wavelengths, as well as thousands of pointed
observations. The current catalogue was constructed from the data
taken in the pointed observation mode with one of the onboard
instruments, the IRC (Infrared Camera) at 9 and 18µm. An archive
of IRC slow- scan observations comprising about 1000 images was used
to search for serendipitous encounters of known asteroids.

Note (1): Num, Name, and ProvDes are the asteroid number, the name, and
the provisional designation, which follow the formal assignment overseen by
the IAU Minor Planet Center.
Note (2): HMAG and GPAR are the absolute magnitude and slope parameter taken
from the Asteroid Orbital Elements Database of the Lowell observatory.
Note (3): Number of detections at S9W (9µm band) and L18W (18µm band) in
total.
Note (4): Estimated size (diameter) and albedo, while e_Diam and e_Albedo
are their uncertainties estimated from the thermal model calculations
(NEATM; Harris 1998Icar..131..291H 1998Icar..131..291H).
