| Abstract;We have performed near-IR photometric and spectroscopic observations of a D-type asteroid, 773 Irmintraud, by SUBARU/IRCS. We also conducted the visible photometry to obtain the accurate lighteurve in Japan. In contrast to the previous observations of D-type asteroids, we found a gap between K- and L- band spectra, possibly due to 3-.MU. m absorptions of hydrous silicates. Our results support the idea that Tagish Lake meteorite has a link with D-type asteroids. (author abst.) |
