5-14 μm Spitzer spectra of Themis family asteroids
Context. The Themis collisional family is one of the largest and best established families in the main belt. Composed of primitive asteroids, there is evidence...
A comparative analysis of the outer-belt primitive families
Context. Asteroid families are witnesses to the intense collisional evolution that occurred on the asteroid belt. The study of the physical properties of family...
A comprehensive study of the opposition effect on 15 NEOs
We report the results we derived analyzing photometric measurements obtained at different phase angles for 15 Near-Earth Objects (NEOs), observed from Campo...
A cost-effective search for extraterrestrial probes in the Solar system
For centuries, astronomers have discussed the possibility of inhabited worlds ─ from Herschel's 18th-century observations suggesting Mars may host life, to the...
A dearth of small particles in the transiting material around the white dwarf WD 1145+017
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves...
A dedicated survey of fast-rotating near-Earth asteroids with the Two-meter Twin Telescope: I. Observational strategy and first results
Context. The rotational properties of small near-Earth asteroids (NEAs) provide crucial insights into their internal structure and collisional history. However...
A Short-duration Event as the Cause of Dust Ejection from Main-Belt Comet P/2012 F5 (Gibbs)
We present observations and an interpretative model of the dust environment of the Main-Belt Comet P/2010 F5 (Gibbs). The narrow dust trails observed can be...
A stellar occultation by the transneptunian object (50000) Quaoar observed by CHEOPS
Context. Stellar occultation is a powerful technique that allows the determination of some physical parameters of the occulting object. The result depends on...
Main Belt Comets (MBCs) exhibit sublimation-driven activity while occupying asteroid-like orbits in the Main Asteroid Belt. MBCs and candidates show stronger...
