Computation of asteroid proper elements: Recent advances [PDF]

open access: yesSerbian Astronomical Journal, 2017
The recent advances in computation of asteroid proper elements are briefly reviewed. Although not representing real breakthroughs in computation and stability assessment of proper elements, these advances can still be considered as important improvements

Computation of asteroid proper elements on the Grid [PDF]

open access: yesSerbian Astronomical Journal, 2009
A procedure of gridification of the computation of asteroid proper orbital elements is described. The need to speed up the time consuming computations and make them more efficient is justified by the large increase of observational data expected from the

Genetic optimization of asteroid families’ membership

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Asteroid families are groups of asteroids with a common origin, such as prior collisions or the parent body’s rotational fission. In proper [a, e, sin(i)] element domains, they are generally observed using the hierarchical clustering technique (HCMs ...

Third derivatives of the integrable part of an asteroid Hamiltonian [PDF]

open access: yesSerbian Astronomical Journal, 2007
To apply the theorem of Nekhoroshev (1977) to asteroids, one first has to check whether a necessary geometrical condition is fulfilled: either convexity, or quasi-convexity, or only a 3-jet non-degeneracy.

Systematic KMTNet Planetary Anomaly Search. VIII. Complete Sample of 2019 Subprime Field Planets

open access: yesThe Astronomical Journal, 2023
We complete the publication of all microlensing planets (and “possible planets”) identified by the uniform approach of the KMT AnomalyFinder system in the 21 KMT subprime fields during the 2019 observing season, namely, KMT-2019-BLG-0298, KMT-2019-BLG ...

Mercury and orbfit packages for numerical integration of planetary systems: implementation of the yarkovsky and yorp effects [PDF]

open access: yesSerbian Astronomical Journal, 2022
For studies of the long-term evolution of small Solar System objects, it is fundamental to add the Yarkovsky and Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effects in the dynamical model.

Classification of asteroid families with artificial neural networks [PDF]

open access: yesSerbian Astronomical Journal, 2020
This paper describes an artificial neural network for classification of asteroids into families. The data used for artificial neural network training and testing were obtained by the Hierarchical Clustering Method (HCM).

Asteroid spin-rate studies using large sky-field surveys

open access: yesGeoscience Letters, 2017
Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from which we identified two new super-fast rotators (SFRs ...

The physical and dynamical characteristics of the asteroid 4940 Polenov [PDF]

open access: yesSerbian Astronomical Journal, 2021
The asteroid (1986 QY4) 4940 Polenov is the first Solar system object whose 3D shape is determined using the observations from the newly built Astronomical Station Vidojevica (ASV).

Observational Data and Orbits of the Asteroids Discovered at the Baldone Observatory in 2008–2013

open access: yesOpen Astronomy, 2015
The paper presents statistics of the asteroids observed and discovered at the Baldone Observatory, Latvia, in 2008–2013 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets. CCD observations
