![]() A combination of the Bus-DeMeo taxonomy for AcuA-spec asteroids with other physical clues, such as the polarimetric inversion angle, radar albedo, and mid-infrared spectroscopic spectra, will be beneficial for surface material constraints from the AcuA-spec asteroid observations. This supports the proposal regarding the C-complex asteroids (Vernazza et al. As a result, it is suggested that certain C-, Cb-, B-type, dark X-, and D-complex asteroids have spectral properties compatible with those of anhydrous interplanetary dust particles with tiny bright material, such as water ice. Additionally, taking advantage of the Bus-DeMeo taxonomy characteristics, we constrain the characteristic of each spectral type by combining the taxonomy results with the other physical observational data from colorimetry, polarimetry, radar, and radiometry. INTRODUCTION Internationally, the spectral classification of asteroids has been well developed, now the rather mature classification is the Bus-DeMeo taxonomy based on the data of SMASS II (Small Main-belt Asteroid Spectroscopic Survey II) of the Planetary Spectroscopy Group at MIT (Massachusetts Institute of Technology), which classifies the as. 2009, Icarus, 202, 160), all the AcuA-spec asteroids are classified, using both published and our observational data. Based on the Bus-DeMeo taxonomy (DeMeo et al. Following the method of DeMeo & Carry, we define classification criteria on the 2D color plane to assign nine taxonomic types (A, B, C, K, L&D, O, S, V, and X) for the observed objects. (2009), is based on reflectance spectrum characteristics for 371 asteroids measured over the wavelength 0.45 to 2.45 microns. ![]() The Bus-DeMeo asteroid taxonomy classification system, described in DeMeo et al. In the 1-2.5 μm range, spectroscopic observations are made on the AcuA-spec asteroids, the spectra of which were obtained in a continuous covered mode between 2.5-5.0 μm by AKARI. This is the data collection for the bundle. ![]()
