Photometry and Models of Seven Main-Belt Asteroids

open access: yesUniverse
The China Near-Earth Object Survey Telescope (CNEOST) conducted four photometric surveys from 2015 to 2018 using image processing and aperture photometry techniques to obtain extensive light curve data on asteroids. The second-order Fourier series method

SDSS photometry of Asteroids in Cometary Orbits

open access: yes, 2012
Aiming at exploring the relationship between asteroids in cometary orbits and other minor body populations from the observational point of view, I explore the large photometric database of the Sloan Digital Sky Survey - Moving Objects Catalog.

Overview of Water-Ice in Asteroids—Targets of a Revolution by LSST and JWST

open access: yesUniverse
Water-ice occurs inside many minor bodies almost throughout the Solar System. To have an overview of the inventory of water-ice in asteroids, beside the general characteristics of their activity, examples are presented with details, including the Hilda ...

The taxonomic distribution of asteroids from multi-filter all-sky photometric surveys

open access: yes, 2013
The distribution of asteroids across the Main Belt has been studied for decades to understand the compositional distribution and what that tells us about the formation and evolution of our solar system.

Identifying LL Chondrite Near-Earth Asteroids Using LL Chondrite Reflectance Spectra

open access: yesThe Astrophysical Journal Letters
Most near-Earth objects are thought to originate from the collisional fragments of the main asteroid belt. One question that remains to be resolved is the proportion of near-Earth objects sampling the core area material of the parent body to the outer ...
