Discovery, Observational Data and the Orbit of the Transneptunian Object (420356) Praamžius

open access: yesOpen Astronomy, 2016
A project for astrometric and photometric observations of asteroids with the VATT telescope on Mt. Graham is described. One of the most important results is the discovery of the Transneptunian object (420356) Praamžius. We computed its orbit applying 198

Constraining planet formation around 6$M_{\odot}$-8$M_{\odot}$ stars [PDF]

open access: yes, 2020
Identifying planets around O-type and B-type stars is inherently difficult; the most massive known planet host has a mass of only about $3M_{\odot}$. However, planetary systems which survive the transformation of their host stars into white dwarfs can be detected via photospheric trace metals, circumstellar dusty and gaseous discs, and transits of ...

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 ...

Post-main-sequence evolution of icy minor planets. III. water retention in dwarf planets and exo-moons and implications for white dwarf pollution [PDF]

open access: yes, 2017
Studies suggest that the pollution of white dwarf (WD) atmospheres arises from the accretion of minor planets, but the exact properties of polluting material, and in particular the evidence for water in some cases are not yet understood. Previous works studied the water retention in minor planets around main-sequence and evolving host stars, in order ...

Observational data and orbits of the asteroids discovered at the Baldone Observatory in 2015–2018

open access: yesOpen Astronomy, 2020
This paper is devoted to the discovery of 37 asteroids at the Baldone Astrophysical Observatory (MPC 069) from 2015 to 2018, and one of dynamically interesting Mars-crosser (MC) observed at the Baldone Astrophysical Observatory, namely 2008 LX16.

Precise CCD astrometric observations of minor planets and comets at the Belgrade observatory during 1997 [PDF]

open access: yesSerbian Astronomical Journal, 1998
73 precise astrometric positions of seven comets and two minor planets from MPC critical list - 1093 Freda and 4954 Eric - were obtained with the CCD equipped Askania astrograph (13.5/160) of Belgrade Astronomical Observatory.

Making Planet Nine: A Scattered Giant in the Outer Solar System [PDF]

open access: yes, 2016
Correlations in the orbits of several minor planets in the outer solar system suggest the presence of a remote, massive Planet Nine. With at least ten times the mass of the Earth and a perihelion well beyond 100 AU, Planet Nine poses a challenge to planet formation theory.

The Potentially Hazardous Asteroid 2000 SG344

open access: yesOpen Astronomy, 2016
We computed impact solutions for the potentially dangerous asteroid 2000 SG344, based on 31 optical observations from 1999 May 15.20482 UTC to 2010 October 29 03.60723 UTC.

Main Belt Comets and other “Interlopers” in the Solar System

open access: yesUniverse, 2022
According to traditional ideas about the formation of the Solar System starting from a protoplanetary disk of gas and dust, a well-defined distribution of planets and minor bodies is expected: (a) volatile-poor rocky bodies (terrestrial planets and ...
