Asteroid rotation excitation by subcatastrophic impacts [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
Photometric observations of asteroids show that some of them are in non-principal axis rotation state (free precession), called tumbling. Collisions between asteroids have been proposed as a possible asteroid rotation excitation mechanism. We simulated subcatastrophic collisions between asteroids of various physical and material parameters to find out ...

Photometry and Polarimetry of 2010 XC15: Observational Confirmation of E-type Near-Earth Asteroid Pair

open access: yesThe Astrophysical Journal, 2023
Asteroid systems such as binaries and pairs are indicative of the physical properties and dynamical histories of small solar system bodies. Although numerous observational and theoretical studies have been carried out, the formation mechanism of asteroid

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 ...

A Comprehensive Comparison of Period Extraction Algorithms for Asteroids with Long Term Observation

open access: yesUniverse, 2021
The light curve period of an asteroid plays an important role in determining the rotation period, the collision evolution and the YORP effect. There are many period extraction algorithms used to find the light curve period of asteroids with long term ...

Orbital Mechanics near a Rotating Asteroid [PDF]

open access: yesJournal of Astrophysics and Astronomy, 2014
This study investigates the different novel forms of the dynamical equations of a particle orbiting a rotating asteroid and the effective potential, the Jacobi integral, etc. on different manifolds. Nine new forms of the dynamical equations of a particle orbiting a rotating asteroid are presented, and the classical form of the dynamical equations has ...

RESONANCES IN ASTEROID SYSTEMS

open access: yesOdessa Astronomical Publications, 2016
Today the following types of resonances in the rotation of celestial bodies in the solar system are known, namely orbital, spin-orbit and spin-spin resonances.

Preatmospheric Detection of a Meter-sized Earth Impactor

open access: yesThe Planetary Science Journal, 2023
On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound ...

A Photometric Survey of over 200 V-type Asteroids and Their Phase-curve Analysis

open access: yesThe Astrophysical Journal Supplement Series
V-type asteroids are considered to be crustal fragments of asteroid (4) Vesta and possibly of other differentiated parent bodies that once existed in the main asteroid belt.

Asteroids discovered in the Baldone Observatory between 2017 and 2022: The orbits of asteroid 428694 Saule and 330836 Orius

open access: yesOpen Astronomy
We discovered 83 asteroids at the Baldone Astrophysical Observatory (MPC code 069) in 2017–2022. We studied one of the dynamically interesting Apollo (Near Earth object) observed at the Baldone Astronomical Observatory, namely 428694 Saule (2008 OS9) and
