We present results of some numerical studies on the dynamical history of a large number of observed long-period comets. In our investigations we include all comets with good quality orbits. We calculated barycentric, original orbital elements for comets at a distance of 250 AU from the Sun and then followed the motion of each comet (elliptic orbits only) backwards to its aphelion and then to its previous perihelion passage, including the galactic perturbations. Several previously published…

Long-period comet flux in the planetary region: Dynamical evolution from the Oort cloud
This study analyzes the evolution of 2 × 105 orbits with initial parameters corresponding to the orbits of comets of the Oort cloud under the action of planetary, galactic, and stellar perturbations
Near-parabolic comets observed in 2006–2010 – II. Their past and future motion under the influence of the Galaxy field and known nearby stars
Here, we continue this research with a detailed study of their past and future motion during previous and next orbital periods under the perturbing action of our Galactic environment. At all stages
Where do long‐period comets come from? Moving through the Jupiter–Saturn barrier
The past and future dynamical evolution of all 64 long-period comets having 1/aori 3.0 au and discovered after 1970 is studied. For this sample of Oort-spike comets we have obtained a new,
Where do long‐period comets come from? 26 comets from the non‐gravitational Oort spike
Since 1950, when Oort published his hypothesis, several important new facts have been established in this field. At present, there are still questions surrounding the apparent source region (or
The last revolution of new comets: the role of stars and their detectability
Context. This work is a follow-up of a previous study, where we simulated the dynamical evolution of the Oort Cloud over 5 Gyr with special attention to the injection of comets into observable
Magnitude and size distribution of long-period comets in Earth-crossing or approaching orbits
We analyse the population of near-Earth long-period comets (LPCs; perihelion distances q 103 yr). We have considered the sample of LPCs discovered during the period 1900–2009 and their estimated
New orbit recalculations of comet C/1890 F1 Brooks and its dynamical evolution
C/1890 F1 Brooks belongs to a group of nineteen comets used by Jan Oort to support his famous hypothesis on the existence of a spherical cloud containing hundreds of billions of comets with orbits of
Towards a better understanding of the apparent source/sources of long period comets
Abstract We report the current status of the on-going project aimed at advancing our understanding of a source or sources of the actual long-period comets (LPCs). For the last several years we have
The structure of the inner Oort cloud from the simulation of its formation for 2 Gyr
Considering the model of the initial disc of planetesimals consisting of 10 038 test particles, we simulated the formation of the distant comet reservoirs up to 2 Gyr. The result concerning the outer
Near-parabolic comets observed in 2006–2010. The individualized approach to 1/a-determination and the new distribution of original and future orbits
Dynamics of a complete sample of 22 small perihelion distance near-parabolic comets discovered in the years 2006 - 2010 is studied. First, osculating orbits are obtained after a careful positional


New osculating orbits for 110 comets and analysis of original orbits for 200 comets
Osculating orbits are presented for 110 nearly parabolic comets. Combining these with selected orbit determinations from other sources, a total of 200 orbits are considered where the available
Comets (Existing Populations)
The definition, population, extent, origin and evolution of the individual subsystems of comets and transitions between them are discussed, together with presentation of the relevant statistical data
The galactic disk tidal field and the nonrandom distribution of observed Oort cloud comets
Abstract We consider the interaction of the galaxy with the Oort cloud of comets. If the perturbation is limited to the secularly averaged first-order disk tidal term, analytic solutions for the time
The past and future motion of comet P/Swift-Tuttle
The orbit of P/Swift-Tuttle is investigated by way of a long-term integration forward to AD 2392 and backward to 703 BC. Two of its previous returns prior to the telescopic period, in AD 188 and 69
The influence of the Galactic tidal field on the Oort comet cloud
We examine the effect of the Galactic disk potential on the Oort cloud. The tidal force from the disk produces a slow drift of a comet's orbital angular momentum, J. If J is reduced below a critical
The activities of comets related to their aging and origin
Two indices have been developed for the purpose of comparing the natures of various classes of comets. The first is the Activity Index (AI), measuring the inherent magnitude increase in brightness
A volatility index for comets
Abstract A volatility index, VI, as defined, measures the variations in total brightness of a comet when it is most active near perihelion. The highly consistent cometary magnitude measurements taken
Stellar Encounters with the Oort Cloud Based on Hipparcos Data
We have combined Hipparcos proper-motion and parallax data for nearby stars with ground-based radial velocity measurements to —nd stars that may have passed (or will pass) close enough to the Sun to
Diversity and similarity of comets
The evolution of comets from an early stage where they were all similar, to the later diversity is reviewed. The elemental abundances of all pristine comets are likely to be primitive, that is in
New Runge-Kutta algorithms for numerical simulation in dynamical astronomy
Some new Runge-Kutta and Runge-Kutta-Nystrom algorithms are presented for the solution of ordinary differential equations of the initial value type. The methods are compared with others in
