Terrestrial Planet Formation Constrained by Mars and the Structure of the Asteroid Belt

open access: yes, 2015
Reproducing the large Earth/Mars mass ratio requires a strong mass depletion in solids within the protoplanetary disk between 1 and 3 AU. The Grand Tack model invokes a specific migration history of the giant planets to remove most of the mass initially ...

The collisional evolution of undifferentiated asteroids and the formation of chondritic meteoroids [PDF]

open access: yes, 2016
Most meteorites are fragments from recent collisions experienced in the asteroid belt. In such a hyper-velocity collision, the smaller collision partner is destroyed, whereas a crater on the asteroid is formed or it is entirely disrupted, too.

ACCURACY OF MYKOLAIV ASTEROID OBSERVATIONS WITH DIFFERENT REFERENCE CATALOGUES

open access: yesOdessa Astronomical Publications, 2017
The  results  of  astrometric  reductions  of main belt asteroid observations  with  usage of 3 different reference  catalogues  are  presented.  The  high  precision catalogs CMC15, UCAC4 and GAIA DR1 were used as reference  catalogues  for  calculation

Jovian Early Bombardment: planetesimal erosion in the inner asteroid belt

open access: yes, 2012
The asteroid belt is an open window on the history of the Solar System, as it preserves records of both its formation process and its secular evolution.

The distribution of basaltic asteroids in the Main Belt [PDF]

open access: yesIcarus, 2008
We present the observational results of a survey designed to target and detect asteroids whose colors are similar to those of Vesta family members and thus may be considered as candidates for having a basaltic composition. Fifty basaltic candidates were selected with orbital elements that lie outside of the Vesta dynamical family.

Size and Albedo Constraints for (152830) Dinkinesh Using WISE Data

open access: yesThe Astrophysical Journal Letters, 2023
Probing small main-belt asteroids provides insight into their formation and evolution through multiple dynamical and collisional processes. These asteroids also overlap in size with the potentially hazardous near-Earth object population and supply the ...

Study the genesis of the Moons of Jupiter and their Physical Properties

open access: yesمجلة بغداد للعلوم, 2015
A developed model has been put for the hypothesis of capturing moons in explaining the origin of Jupiter moons, and study the change of the orbital properties of these satellites as well as the distance from the planet.

Hiding Dust around ϵ Eridani

open access: yesThe Astronomical Journal, 2023
With a Jupiter-like exoplanet and a debris disk with both asteroid and Kuiper Belt analogs, ϵ Eridani has a fascinating resemblance to our expectations for a young solar system.

Mean Motion Resonances in the Asteroid Belt [PDF]

open access: yesInternational Astronomical Union Colloquium, 1999
The Kirkwood gaps in the main asteroidal belt (2 – 3.5 AU) coincide with the mean motion resonances with Jupiter (4/1, 3/1, 5/2, 7/3, 2/1). Similarly, several narrower gaps are observed in the outer asteroid belt (3.5 – 4 AU) at places of 11/6, 9/5, 7/4 and 5/3 Jovian resonances (Holman and Murray 1996).

X-Ray Emission Spectroscopy Analysis for Near-Asteroid Belt of Atmospheric of the Comets

open access: yesIraqi Journal of Physics, 2022
         According to Chandra Survey Observatory Near-Asteroid Belt Comets, the solar wind's contact with the comet produces a variety of spectral characteristics. The study of X-ray spectra produced by charge exchange is presented here. The spectrum of
