Puzzling rotation of asteroid 288 Glauke

Nonextensive distributions of asteroid rotation periods and diameters

Context. We investigate the distribution of asteroid rotation periods from different regions of the solar system and diameter distributions of near-Earth asteroids (NEAs). Aims. We aim to verify if nonextensive statistics satisfactorily describes the data. Methods. Light curve data were taken from the Planetary Database System (PDS) with Rel ≥ 2. We also considered the taxonomic class and regio...

Rotation-Resolved Spectroscopy of a Very Young Asteroid, (1270) Datura

(1270) Datura is the largest member of a very young asteroid cluster that was thought to be broken-up 0.45 Myr ago. The light-curve and the rotationresolved reflectance spectra (0.6 μm – 1.0 μm) were observed in order to find “fresh” surface. Our data show no significant spectral variation along the rotation phase. The depth of the 0.95 μm absorption band, which indicates the degree of space we...

The Puzzling Mutual Orbit of the Binary Trojan Asteroid (624) Hektor

Asteroids with satellites are natural laboratories to constrain the formation and evolution of our solar system. The binary Trojan asteroid (624) Hektor is the only known Trojan asteroid to possess a small satellite. Based on W. M. Keck adaptive optics observations, we found a unique and stable orbital solution, which is uncommon in comparison to the orbits of other large multiple asteroid syst...

Asteroid Rotation and Orbit Control via Laser Ablation

Op-brai130314 288..293

Several studies have demonstrated enhanced auditory processing in the blind, suggesting that they compensate their visual impairment in part with greater sensitivity of the other senses. However, several physiological studies show that early visual deprivation can impact negatively on auditory spatial localization. Here we report for the first time severely impaired auditory localization in the...
