CCD astrometric observations of minor planets at the Belgrade observatory during 1999 (II) [PDF]

open access: yesSerbian Astronomical Journal, 2001
76 precise astrometric positions of six observed minor planets (two NEO among them) are calculated. The SBIG ST-8 camera attached to Askania astrograph of Belgrade Observatory was used in the observations.

People Love to Name Things: Current Trends in Naming Minor Planets

open access: yesВопросы ономастики
After several introductory remarks regarding the onomastic terminology used for names of celestial objects, the article proposes a semantic and a limited formal analysis of the minor planet names officially published in 2022 by the International ...

The Proximities of Asteroids and Critical Points of the Distance Function [PDF]

open access: yesSerbian Astronomical Journal, 2010
The proximities are important for different purposes,for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets.

A potential survival strategy during the late heavy bombardment [PDF]

open access: yesSerbian Astronomical Journal, 2023
The Late Heavy Bombardment (LHB) represents a period of time in which an increased number of impactors collided with the Earth. While there were continuous collisions of impactors globally, these would be perceived by populations of life as ...

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 ...

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.

Microlensing for extrasolar planets : improving the photometry [PDF]

open access: yes, 2013
Gravitational Microlensing, as a technique for detecting Extrasolar Planets, is recognised for its potential in discovering small-mass planets similar to Earth, at a distance of a few Astronomical Units from their host stars.

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 ...

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

Survey of secular resonances in the asteroid belt [PDF]

open access: yesSerbian Astronomical Journal, 2022
Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.
