The Greek presence on the east coast of the Iberian Peninsula: Colonial establishments and rhythms of trade with Iberian societies [PDF]

open access: yes, 2014
The Greek presence along the Mediterranean coastline of the Iberian Peninsula is a phenomenon that we can trace from the Archaic Period until the beginning of the Roman Empire.

Asteroid families classification: exploiting very large data sets

open access: yes, 2014
The number of asteroids with accurately determined orbits increases fast. The catalogs of asteroid physical observations have also increased, although the number of objects is still smaller than in the orbital catalogs. We developed a new approach to the

Constraining the cometary flux through the asteroid belt during the late heavy bombardment

open access: yes, 2013
In the Nice model, the late heavy bombardment (LHB) is related to an orbital instability of giant planets which causes a fast dynamical dispersion of a transneptunian cometary disk.

Automated detection of asteroids in real-time with the Spacewatch telescope [PDF]

open access: yes
The Spacewatch telescope on Kitt Peak is being used to survey for near-earth asteroids using a Tektronix TK2048 CCD in scanning mode. We hope to identify suitable low delta v candidates amongst the near-earth asteroid population as possible exploration ...

A computer search for asteroid families [PDF]

open access: yes
The improved proper elements of 4100 numbered asteroids have been searched for clusterings in a, e, i space using a computer technique based on the D-criterion. A list of 14 dynamical families each with more than 15 members is presented.

Secular resonance sweeping of the main asteroid belt during planet migration

open access: yes, 2011
We calculate the eccentricity excitation of asteroids produced by the sweeping $\nu_6$ secular resonance during the epoch of planetesimal-driven giant planet migration in the early history of the solar system.

Dynamical evolution and chronology of the Hygiea asteroid family

open access: yes, 2013
The asteroid (10) Hygiea is the fourth largest asteroid of the Main Belt, by volume and mass, and it is the largest member of its own family. Previous works investigated the long-term effects of close encounters with (10) Hygiea of asteroids in the ...

The Compositional Structure of the Asteroid Belt

open access: yes, 2015
The past decade has brought major improvements in large-scale asteroid discovery and characterization with over half a million known asteroids and over 100,000 with some measurement of physical characterization.

O papel de Éfeso na Antiguidade Tardia desde o período de Diocleciano até o Concílio dos ladrões [PDF]

open access: yes, 2018
