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

Mitogenomics provides new insights into the phylogenetic relationships and evolutionary history of deep-sea sea stars (Asteroidea)

open access: yesScientific Reports, 2022
The deep sea (> 200 m) is considered as the largest and most remote biome, which characterized by low temperatures, low oxygen level, scarce food, constant darkness, and high hydrostatic pressure.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Period-Multiplying Bifurcations in the Gravitational Field of Asteroids

open access: yesAerospace
Periodic orbit families around asteroids serve as potential trajectories for space probes, mining facilities, and deep space stations. Bifurcations of these families provide additional candidate orbits for efficient trajectory design around asteroids ...

Research of resonant motion of Apollo asteroids with inner planets

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We study the resonant motion of Apollo asteroids with inner planets (Venus, Earth, Mars). It is shown that 1760 among 2026 Apollo asteroids move in resonance with one, two or three inner planets.

Neil Gehrels–Swift Observatory’s Ultraviolet/Optical Telescope Observations of Small Bodies in the Solar System

open access: yesUniverse, 2023
The Neil–Gehrels Swift Observatory has added extensively to our understanding of small bodies in our solar system through its capabilities to rapidly respond to short-live events such as outbursts and collisions, through its near-ultraviolet coverage ...

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2016
The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...
