Albedos of Main-Belt Comets 133P/Elst-Pizarro and 176P/LINEAR
ASTROPHYSICAL JOURNAL LETTERS, no. 2 (2009): L111-L114
摘要
We present the determination of the geometric R-band albedos of two main-belt comet (MBC) nuclei based on data from the Spitzer Space Telescope and a number of ground-based optical facilities. For 133P/Elst-Pizarro, we find an albedo of p(R) = 0.05 +/- 0.02 and an effective radius of r(e) = 1.9 +/- 0.3 km (estimated semiaxes of a similar ...更多
