Asteroid Searches from UKST Material

1992
The UK Schmidt Telescope (UKST) has been involved in asteroid work since 1979, initially on the UK-Caltech Asteroid Survey (UCAS) and more recently with the Lowell-UK Asteroid Survey (LUKAS). In addition to these major programs, a number of smaller projects have been undertaken. These include searches for Trojan asteroids of Saturn and Jupiter, distant

Observation of Asteroids for Searching Extraterrestrial Artifacts

2013
Since the beginning of modern astronomy all evidence indicates that mankind’s place in the Universe is not central or exceptional. A major step was made into this direction recently when the availability of very high resolution spectrographs made it possible to detect giant and subgiant planets around Sun-like or smaller stars (Mayor 1995) and it was ...

Asteroid Families: Search of a 12,487-Asteroid Sample Using Two Different Clustering Techniques

Icarus, 1995
A sample of over 12,487 asteroid proper element triplets, computed by A. Milani and Z. Kneževic (1994, Icarus 107, 219-254), has been searched for statistically significant and robust families by both the hierarchical clustering (HCM) and the wavelet analysis (WAM) automated techniques.

Search for correlation between asteroid families and classes

Icarus, 1977
A correlation between membership in a dynamically defined asteroid family and membership in a given asteroid spectral class is sought. Examination of 10 families each with five or more classified members indicates a correlation for the 4 families whose existence is best established, and no correlation for the remaining 6 families.

The Asteroid-Comet Continuum: In Search of Lost Primitivity

Elements, 2011
Recent results from the Stardust comet sample-return mission have confirmed the idea that there is a continuum between primitive small bodies in the outer main asteroid belt and comets. Indeed, the mineralogy as well as the chemical and oxygen isotope compositions of the dust from comet Wild 2 are very similar to those of carbonaceous chondrites, a ...

Searching and Studying Binary Asteroids with AO Systems

2003
Our group has conducted adaptive optics observations of asteroids since 2001. Our main goal is the search and study of binary asteroids using several AO systems (Lick, Keck, VLT) and related technique such as Appulse (Berthier and Marchis, 2002) and Laser Guide Star observations (Marchis et al., AGU-EGS, 2003) to broaden the sample of asteroids ...

Some Results of the Faint Asteroid Search in Tautenburg

1988
In the last 20 years the whole world has witnessed an unexpected boom in minor planet astronomy. This was mainly due to the applica­tion of ever more sophisticated computers in calculating astrome­trio positions, orbital elements and ephemerides in the shortest possible time and storing a vast number of asteroid data.
