Radar investigation of asteroids and planetary satellites

open access: green, 1988
The aim is to make radar reconnaissance of near-Earth asteroids, mainbelt ateroids, the Galilean satellites, the Martian satellites, and the largest Saturnian satellites, using the Arecibo 13-cm and the Goldstone 3.5-cm systems.

First observation of a quadruple asteroid. Detection of a third moon around (130) Elektra with SPHERE/IFS [PDF]

open access: yesAstronomy & Astrophysics, 2022
Aims. We aim to increase the contrast limits to detect new satellites orbiting known asteroids. We use cutting-edge data reduction techniques and data processing algorithms that are essential to best analyse the raw data provided by the instruments and ...

Physical Properties of the Young Asteroid Pair 2010 UM26 and 2010 RN221

open access: yesThe Astronomical Journal, 2023
The main belt asteroids 458271 (2010 UM26) and 2010 RN221 share almost identical orbital elements, and currently appear as comoving objects ∼30″ apart in the plane of the sky.

The Moon at thermal infrared wavelengths: a benchmark for asteroid thermal models [PDF]

open access: yesAstronomy & Astrophysics, 2021
Thermal-infrared measurements of asteroids, satellites, and distant minor bodies are crucial for deriving the objects’ sizes, albedos, and in some cases, also the thermophysical properties of the surface material.

Yarkovsky effect detection from ground-based astrometric data for near-Earth asteroid (469219) Kamo'oalewa

open access: yesAstronomy & Astrophysics, 2022
Context. The Yarkovsky effect is a weak non-gravitational force but may significantly affect sub-kilometre-sized near-Earth asteroids. Yarkovsky-related drift may be detected, in principle, from astrometric or radar datasets of sufficient duration. To date,

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.

Design and ballistic analysis of the mission for long-term study of the asteroid Apophis by a nanosatellite with an electric rocket propulsion system

open access: yesКосмические аппараты и технологии, 2020
The paper considers non-spherical objects with low gravitational attraction, such as asteroids, satellites of the planet and comets. We considered possibility of a mission to small bodies of the solar system of irregular shape on the example of the ...

Arecibo radar observations of near-Earth asteroid (3200) Phaethon during the 2017 apparition [PDF]

open access: yesPlanetary and Space Science, 2019
We report Arecibo S-band (2380 MHz; 12.6 cm) radar observations of near-Earth asteroid (3200) Phaethon during the December 2017 apparition when Phaethon passed within 0.07 au of Earth.
