| 英文摘要 | To study the secular evolution of the activity of Centaur 166P/2001 T4 (Near Earth Asteroid Tracking, NEAT) and its physical properties, we present the results of optical observations of the Centaur taken on 2009 March 29 with the Keck 10-m telescope located atop Mauna Kea, Hawaii. It was still active at r(h) = 11.9 au post-perihelion. An upper limit of the nucleus radius of a(N) < 14.32 km is derived. The colour index is B - R = 1.59 +/- 0.05. The Af rho value is measured to be 288 +/- 19 cm and the corresponding dust production rate is 252 kg s(-1). Finally, a possible mechanism of activity is discussed. |
