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

Asteroid families—An initial search

Icarus, 1992
A stereo examination was conducted for clusters in three-dimensional proper element space within a sample of both numbered and faint Palomar-Leiden Survey (PLS) asteroids. The clusters were then objectively filtered for small Poisson probability of chance occurrence; 104 were accepted as families with 4- to 12-member populations, and are interpreted as

Search for solar wind–asteroid interactions at Eros

Advances in Space Research, 2004
The solar wind interaction with the asteroid 433 Eros is investigated using magnetometer data from the NEAR-Shoemaker spacecraft. From February 2000 to February 2001 NEAR-Shoemaker orbited Eros in nearly circular orbits having radii of 200, 100, 50 and 35 km.

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.

Comets and asteroids: searches and scares

Advances in Space Research, 2004
Abstract Concern that the Earth might be struck by a comet, with potentially devasting consequences, dates back some two centuries. With the growing appreciation in the twentieth century that asteroidal impacts are also a danger, search programs have been devised in the hope of discovering a specific hazard at least decades, and probably centuries or

Asteroid search operations with the space surveillance telescope

2016 IEEE Aerospace Conference, 2016
Over the past two years, the Lincoln Near Earth Asteroid Research (LINEAR) program, funded by the National Aeronautics and Space Administration (NASA), has transitioned to asteroid search operations using the new 3.5-meter wide-field-of-view Space Surveillance Telescope (SST) located at the Atom Site on White Sands Missile Range, N.M.

A new asteroid observation and search technique

Publications of the Astronomical Society of the Pacific, 1981
A prototype observatory was constructed near Socorro, New Mexico to search for and observe earth-approaching asteroids. Hardware modifications were made so that the discrimination of artificial satellites at an angular speed of 15 arcsec/sec can be used to observe minor planets at an angular speed of 0.01 arcsec/sec.

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.

Asteroid Thermal Radiation Inspired Search

The thermal radiation process of an asteroid exhibits complex dynamics involving energy absorption, storage, conduction, and re-release. Its dynamics are influenced by multiple factors, including rotation, surface roughness, thermal inertia, and asymmetric radiation.

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 ...
