INVESTIGATIONS OF SURFACES OF ATMOSPHERE LESS BODIES USING SCATTERED SOLAR LIGHT

open access: yesOdessa Astronomical Publications, 2017
Sunlight scattered by surfaces of atmosphere less bodies carry information about details of these surfaces. Burns and Tedesco in 1979 published formula for estimations of dimensions of details located on surfaces of asteroids.

The origin of planetary impactors in the inner solar system [PDF]

open access: yes, 2005
New insights into the history of the inner solar system are derived from the impact cratering record of the Moon, Mars, Venus and Mercury, and from the size distributions of asteroid populations. Old craters from a unique period of heavy bombardment that

Surface Geology of Jupiter’s Trojan Asteroids

open access: yesSpace Science Reviews, 2023
AbstractThe surface geology of Jupiter’s Trojan asteroids is one of the scientific investigations of the NASALucymission. A dedicated Geology Working Group will implement these studies using primarily panchromatic and color imaging data and complement the interpretation of these data with theoretical models, such as collisional evolution models ...

Near-IR Spectral Observations of the Didymos System: Daily Evolution Before and After the DART Impact Indicates that Dimorphos Originated from Didymos

open access: yesThe Planetary Science Journal, 2023
Ejecta from Dimorphos following the DART mission impact significantly increased the brightness of the Didymos–Dimorphos system, allowing us to examine subsurface material.

Albedo heterogeneity on the surface of (1943) Anteros [PDF]

open access: yes, 2009
We have investigated the effect of rotation on the polarization of scattered light for the near-Earth asteroid (1943) Anteros using the Dual Beam Imaging Polarimeter on the University of Hawaii's 2.2 m telescope.

Laboratory impact splash experiments to simulate asteroid surfaces [PDF]

open access: yesIcarus, 2020
Granular material that is bound by the low gravity of a small asteroid is mobilized by slow velocity impacts. These splashes generated by impacts might play an important role in sculpting the asteroid's surface. In laboratory experiments we characterize the ejecta generated by spherical 150 $\rm m$ diameter basalt grains impacting a granular bed at 0.

Constraining the Limitations of NEATM-like Models: A Case Study with Near-Earth Asteroid (285263) 1998 QE2

open access: yesThe Planetary Science Journal, 2023
Near-Earth asteroids (NEAs) are a key test bed for investigations into planet formation, asteroid dynamics, and planetary defense initiatives. These studies rely on understanding NEA sizes, albedo distributions, and regolith properties.

ADAM: a general method for using various data types in asteroid reconstruction [PDF]

open access: yes, 2015
We introduce ADAM, the All-Data Asteroid Modelling algorithm. ADAM is simple and universal since it handles all disk-resolved data types (adaptive optics or other images, interferometry, and range-Doppler radar data) in a uniform manner via the 2D ...
