Aggregate dust model to study the polarization properties of comet C/1996 B2 Hyakutake
《Research in Astronomy and Astrophysics》2010年第4期355-362,共8页Himadri Sekhar Das Abinash Suklabaidya Saonli Datta Majumder Asoke Kumar Sen 
The observed linear polarization data of comet Hyakutake are studied at wavelengths λ=0.365 μm,λ=0.485 μm and 0.684μm through simulations using Ballistic Particle-Cluster Aggregate and Ballistic Cluster-Cluster A...

POSITION OBSERVATIONS OF THE COMET HYAKUTAKE
《中国科学院上海天文台年刊》2000年第S1期251-254,共4页Wu Guangjie Ji Kaifan (Yunnan Astronomical Observatory and United Laboratory of Optical Astronomy, Kunming, Yunnan, 650011, P.R. China) 
On March 16 of 1996, we used a new developed 1024×1024 CCD camera attached to the 1 meter telescope at Yunnan Observatory, to take photometric observations for the Comet Hyakutake. The positions have been measured ac...

大彗星Hale-Bopp和Hyakutake来了
《自然杂志》1996年第3期160-164,共5页胡中为 
Shemaker-Levy9彗星撞击木星的轰动事件令人类更关心彗星撞击地球的问题,接近地球的彗星尤其引人注意,1995年发现了Hale-Bopp彗星,预报它在1997年3月23日从离离地球1.98×10z^8km飞过...
