SummaryLarge particles released from the nucleus of comet Halley, but undetected directly by space probes, seem to affect decisively the mass loss and mass determination of the comet, and consequently its aging. Simultaneous radar meteor observations in 1985–86 at the approaches of the comet emphasize the relatively larger proportion of long-duration echoes with respect to previous years. 

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,

Comparison of some characteristics of comets 1P/Halley and 67P/Churyumov–Gerasimenko from the Vega and Rosetta mission data

On March 6 and 9, 1986, for the first time in the history of science, the Russian spacecraft Vega-1 and -2 approached the nucleus of comet 1P/Halley and flew by at a small distance. A while later, on

Impact of a Pioneer/Rindler-type acceleration on the Oort cloud

According to a recent modified model of gravity at large distances, a radial constant and uniform extra-acceleration A_Rin of Rindler type acts upon a test particle p in the static field of a central

Exocometary Activity Around Stars at Different Evolutionary Stages: Current Issues

Modern theories of planetary system formation predict a large population of planetesimals, which are remnants of the primordial matter of the protoplanetary cloud and, at the same time, embryos of

Damping-Antidamping Effect on Comets Motion

We make an observation about Galilean transformation on a 1-D mass variable system which leads us to the right way to deal with mass variable systems. Then using this observation, we study two-body

Disrupted exoplanet systems in the SuperWASP Archive

The aim of this research project has been to search for disrupted or disintegrating exoplanets; this search has been carried out using archival data from the Super-WASP (Wide Angle Search for

Two bodies gravitational systems with variable mass and damping-antidamping effect due to star wind

We study two-bodies gravitational problem where the mass of one of the bodies varies and suffers a damping-antidamping effect due to star wind during its motion. A constant of motion, a Lagrangian

A Climatic Investigation of Ammonia as a Remote Biosignature on Cold Haber Worlds

The study of exoplanet atmospheres for possible biosignatures will continue to dominate our understanding of surface-based habitability on planets outside our solar system over the coming decades. In

Temperature and thermal emission of cosmic dust around the Sun, Vega and Fomalhaut



Composition of comet Halley dust particles from Vega observations

The dust impact mass analyser (PUMA) carried by the spacecraft Vega 1 and Vega 2 has provided the first direct measurements of the physical and chemical properties of cometary dust. Particles of mass

The long-term motion of comet Halley

The orbital motion of comet Halley is numerically integrated back to 1404 BC. Starting with an orbit based on the 1759, 1682, and 1607 observations of the comet, the integration was run back in time

The flux of meteoroids in the vicinity of the orbit of Comet Halley

SummaryOn the basis of simultaneous observations of the Orionid meteor shower in Italy and Czechoslovakia during the period 1978–1982 the flux densities of meteor particles in the near-perihelion

Dust density and mass distribution near comet Halley from Giotto observations

The dust impact detection system (DIDSY) carried by the Giotto spacecraft has measured the density and mass spectrum (in the range 10−20–10−8 kg) of the dust near comet Halley. Profiles of the dust

A radar study of Comet IRAS-Araki-Alcock 1983d

Radar echoes from Comet IRAS-Araki-Alcock at wavelengths 3.54 and 12.9 cm indicate that the comet's nucleus is very rough on a scale larger than the radar wavelengths; however, the low polarization

Some Remarks on the Density of Interplanetary Dust Grains

The relevance of the bulk density as a physical parameter characterizing interplanetary dust grains is discussed. The various measurements which lead to a determination of this parameter are

Secular Perturbations of Asteroids and Comets

In 1962 the author published a paper on secular perturbations of asteroids with high eccentricity and inclination (Kozai, 1962) and found that for such asteroids the secular perturbations are more

Television observations of comet Halley from Vega spacecraft

The television system (TVS) aboard the spacecraft Vega 1 and Vega 2 observed comet Halley from 4 to 11 March 1986, and transmitted ∼1,500 images to Earth. The best images of the cometary nucleus were
