Abstract

“The Great Comet of 1997” was a significant event in cometary physics. Numerous interesting scientific studies are devoted to this comet. Unfortunately, in the Russian scientific literature, there are few publications on investigations of Comet Hale–Bopp. This study is timed to the twentieth anniversary of finishing the main observations of this comet and reminds the readers about some of its unusual and even unique features without pretending to present an exhaustive review of the published materials. In this paper, an attempt is made to estimate the mass of the nucleus of Comet Hale–Bopp and it is supposed that it may be close to the initial mass of Halley’s comet which the latter had in the beginning of its evolution. Based on the published images of this comet, the approximate velocity of the gas-dust ejections and the spread of the velocities are calculated. A possible relation between the mass of the total losses and the dynamics of the comet nucleus is considered.

黑尔-波普彗星的某些特征（根据1995-1998年的观测）

摘要

“ 1997年大彗星”是彗星物理学中的重要事件。对该彗星进行了大量有趣的科学研究。不幸的是，在俄罗斯科学文献中，很少有关于黑尔-波普彗星研究的出版物。这项研究的时间定为完成对这颗彗星的主要观察二十周年，并提醒读者注意它的一些不寻常甚至独特的功能，而又不假装对已出版的材料进行详尽的评论。在本文中，试图估算黑尔-波普彗星核的质量，并认为它可能接近哈雷彗星在其演化开始时的初始质量。根据此彗星的已发布图像，计算出气尘喷出的近似速度和速度的分布。考虑了总损失质量与彗核动力学之间的可能关系。
