Aims. We present a comparative analysis of the spectral slope and color distributions of Jupiter Trojans, with particular attention to asteroid families. We use a sample of data from the Moving Object Catalog of the Sloan Digital Sky Survey, together with spectra obtained from several surveys. Methods. We extracted a first sample of 349 observations, corresponding to 250 Trojan asteroids, from the Sloan Digital Sky Survey, and a second sample of 138 spectra, corresponding to 115 Trojans, from… 
The Color–Magnitude Distribution of Hilda Asteroids: Comparison with Jupiter Trojans
Current models of solar system evolution posit that the asteroid populations in resonance with Jupiter are comprised of objects scattered inward from the outer solar system during a period of
The Trojan asteroids, a very substantial population of primitive bodies trapped in Jupiter's stable Lagrange regions, remain quite poorly understood. Because they occupy these orbits, the physical
SDSS photometry of asteroids in cometary orbits
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
Broadband Linear Polarization of Jupiter Trojans
Trojan asteroids orbit in the Lagrange points of the system Sun-planet-asteroid. Their dynamical stability make their physical properties important proxies for the early evolution of our solar
The heart of the swarm: K2 photometry and rotational characteristics of 56 Jovian Trojan asteroids
We present fully covered phased light curves for 56 Jovian Trojan asteroids as observed by the K2 mission of the Kepler space telescope. This set of objects has been monitored during Campaign 6 and
The differing magnitude distributions of the two Jupiter Trojan color populations
The Jupiter Trojans are a significant population of minor bodies in the middle Solar System that have garnered substantial interest in recent years. Several spectroscopic studies of these objects
0.7–2.5μm Spectra of Hilda Asteroids
The Hilda asteroids are primitive bodies in resonance with Jupiter whose origin and physical properties are not well understood. Current models posit that these asteroids formed in the outer solar
We obtained near-infrared (NIR; 0.8–2.5 μm) spectra of seven Jovian Trojan asteroids that have been formerly reported to show silicate-like absorption features near 1 μm. Our sample includes the
WISE/NEOWISE Observations of the Jovian Trojans: Preliminary Results
We present the preliminary analysis of over 1739 known and 349 candidate Jovian Trojans observed by the NEOWISE component of the Wide-field Infrared Survey Explorer (WISE). With this survey the


Spectroscopic observations of Jupiter Trojans
The properties of Jovian Trojan asteroids listed in SDSS Moving Object Catalogue 3
We analyse 1187 observations of about 860 unique candidate Jovian Trojan asteroids listed in the 3rd release of the Sloan Digital Sky Survey (SDSS) Moving Object Catalogue. The sample is complete at
Small main-belt asteroid spectroscopic survey: Initial results
The spectral characterization of small asteroids is important for understanding the evolution of their compositional and mineralogical properties. We report the results of a CCD spectroscopic survey
