This paper reports on the detection of a satellite around the principal nucleus of comet Hale-Bopp. As shown elsewhere, a successful morphological model for the comet's dust coma necessitates the postulation of overlapping jet activity from a comet pair. The satellite has been detected digitally on images taken with the Hubble Space Telescope's Wide Field Planetary Camera 2 in the planetary mode on five days in May–October 1996. An average satellite-to-primary signal ratio is 0.21 ± 0.03, which… 

Dust Morphology Of Comet Hale-Bopp (C/1995 O1). Ii. Introduction Of A Working Model

A Monte Carlo image simulation code for dust features in comets is applied to comet Hale-Bopp in order to model the object's persistent porcupine-like appearance on high-resolution images taken

Orbit Determination and Evolution of Comet C/1995 O1 (Hale-Bopp)

The situation leading to the determination of the Hale-Bopp orbit is discussed, largely in terms of a procedure that generates two sequences of parabolic orbits. The comet is also considered in

The Nucleus of Comet Hale-Bopp (C/1995 O1): Size and Activity

A review of our current understanding of Comet Hale-Bopp’s nuclear size is presented. Currently the best constraints on the effective radiusare derived from late-1996 mid-IR data and near-perihelion

Post-Perihelion HST Observations of Comet Hale-Bopp

Abstract Post-perihelion observations of Comet Hale–Bopp (C/1995 O1) were made with the Hubble Space Telescope (HST) on 27 August 1997 ( r =2.48 AU; Δ=2.99 AU), 11 November 1997 ( r =3.38 AU; Δ=3.31

Search for satellites near comet 67P/Churyumov-Gerasimenko using Rosetta/OSIRIS images

The European Space Agency Rosetta mission reached and started escorting its main target, the Jupiter-family comet 67P/Churyumov-Gerasimenko, at the beginning of August 2014. Within the context of

Modeling of Jets from Comet Hale-Bopp (C/1995 O1): Observations from the Vainu Bappu Observatory

Abstract Jet and shell structures from Comet Hale–Bopp during the period October 1996 to October 1997 using data from the Vainu Bappu Observatory are modeled. Evolution of jet and shell structures

Estimating the Size of Hale-Bopp's Nucleus

A variety of independent methods have been used to estimate the size of the nucleus of comet Hale-Bopp. Several groups have analyzed optical and infrared images of the comet and claim to detect the

Comet Hale—Bopp Shells Expansion: A CCD Study

Using a CCD camera attached to the 0.335 m and 0.20 m reflectors of S.A.S. Observatory (Novara, Italy), we followed the linear jets and shells of comet Hale–Bopp between May 1996 and May 1997. In

Some Features of Comet Hale–Bopp (According to the Observations of 1995–1998)

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,

Modeling Dust Halos in Comet Hale-Bopp (1995 O1): Existence of Two Active Nuclei Unequivocally Implied

The morphology of the comet's expanding, nearly concentric dust halos, which were observed extensively in 1997 February-April, is modeled by employing a Monte Carlo computer-simulation technique. A

The Activity and Size of the Nucleus of Comet Hale-Bopp (C/1995 O1)

Analysis of Hubble Space Telescope (HST) images of comet Hale-Bopp (C/1995 O1) suggests that the effective diameter of the nucleus is between 27 to 42 kilometers, which is at least three times larger
