The NEO Surveyor Near-Earth Asteroid Known Object Model [PDF]

open access: greenThe Planetary Science Journal, 2023
The known near-Earth object (NEO) population consists of over 32,000 objects, with a yearly discovery rate of over 3000 NEOs per year. An essential component of the next generation of NEO surveys is an understanding of the population of known objects ...

Challenges in Identifying Artificial Objects in the Near-Earth Object Population: Spectral Characterization of 2020 SO [PDF]

open access: goldThe Planetary Science Journal
Since the dawn of the Space Age, hundreds of payloads have been launched into heliocentric space. As near-Earth object (NEO) surveys search deeper for small asteroids, more artificial objects in heliocentric orbits are being discovered.

The Large Synoptic Survey Telescope as a Near-Earth Object Discovery Machine [PDF]

open access: green, 2017
Using the most recent prototypes, design, and as-built system information, we test and quantify the capability of the Large Synoptic Survey Telescope (LSST) to discover Potentially Hazardous Asteroids (PHAs) and Near-Earth Objects (NEOs).

Calculation of nonlimit active earth pressure of retaining walls based on curved sliding surface [PDF]

open access: yesScientific Reports
The shape of the sliding surface and the displacement of the wall have important effects on the earth pressure of retaining walls. Taking the cohesive backfill behind the inclined retaining wall as the research object, the relationship between the ...

Algorithms for Moving Object Detection: YSTAR-NEOPAT Survey Program [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2005
We developed and compared two automatic algorithms for moving object detections in the YSTAR-NEOPAT sky survey program. One method, called starlist comparison method, is to identify moving object candidates by comparing the photometry data tables from ...
