K-band imaging observations of the collision of Comet P/Shoemaker-Levy 9 and Jupiter

摘要

We present results of K (2.2 micrometer)-band imaging observations of the collision of Comet P/Shoemaker-Levy 9 and Jupiter obtaind using PANIC (PtSi astronomical near- infrared camera) on the 0.75-m telescope at the South African Astronomical Observatory, Sutherland. Time resolved (30 sec and 10 sec interval) observations of the impacts by 8 fragments (A, E, H, P2, Q1, Q2, S and T) were analyzed and K-band light curves of the impacts A, E, H, Q1 and S were constructed.
