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 ...

Observational Data and Orbits of the Asteroids Discovered at the Baldone Observatory in 2008–2013

open access: yesOpen Astronomy, 2015
The paper presents statistics of the asteroids observed and discovered at the Baldone Observatory, Latvia, in 2008–2013 within the project for astrometric observations of the near-Earth objects (NEOs), the main belt asteroids and comets. CCD observations

Selecting asteroids for a targeted spectroscopic survey

open access: yes, 2014
Asteroid spectroscopy reflects surface mineralogy. There are few thousand asteroids whose surfaces have been observed spectrally. Determining the surface properties of those objects is important for many practical and scientific applications, such as for

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 ...

Narrow band photometry of selected asteroids [PDF]

open access: yes
The CCD photometry of selected asteroids was carried out to check for possible cometary activity in them. To distinguish the asteroids with possible cometary activity from those of the main belt, each object of interest was observed in two filters; one ...

Earth-approaching asteroids: Populations, origin, and compositional types [PDF]

open access: yes
Origin, physical properties, and discovery history of smaller asteroids are reviewed. They appear to link the main belt objects, namely the comets and meteorites.
