Aqueous alteration on main belt primitive asteroids: results from visible spectroscopy
S. Fornasier, C. Lantz, M. A. Barucci +1
This work focuses on the study of the aqueous alteration process which acted in the main belt and produced hydrated minerals on the altered asteroids. The aqueous alteration is par…
Optical Transmission Characterization of Fused Silica Materials Irradiated at the CERN Large Hadron Collider
S. Yang, A. Tate, R. Longo +23
The Target Absorbers for Neutrals (TANs) represent one of the most radioactive regions in the Large Hadron Collider (LHC). Seven 40 cm long fused silica rods with different dopant…
Short-term variability on the surface of (1) Ceres. A changing amount of water ice?
D. Perna, Z. KaÅuchová, S. Ieva +5
Context: The dwarf planet (1) Ceres - next target of the NASA Dawn mission - is the largest body in the asteroid main belt; although several observations of this body have been per…
Comparison of space weathering spectral changes induced by solar wind and micrometeoroid impacts using ion- and femtosecond-laser-irradiated olivine and pyroxene
K. Chrbolková, R. Brunetto, J. Äurech +8
Space weathering is a process that changes the surface of airless planetary bodies. Prime space weathering agents are solar wind irradiation and micrometeoroid bombardment. These p…
Spectral variability on primitive asteroids of the Themis and Beagle families: space weathering effects or parent body heterogeneity?
S. Fornasier, C. Lantz, D. Perna +3
Themis is an old and statistically robust asteroid family populating the outer main belt, and resulting from a catastrophic collision that took place 2.51.0 Gyr ago. Within th…
Na Activation Level Measurements of Fused Silica Rods in the LHC Target Absorber for Neutrals (TAN) Compared to FLUKA Simulations
S. Yang, M. Sabate Gilarte, A. Tate +21
The Target Absorbers for Neutrals (TANs) are located in a high-intensity radiation environment inside the tunnel of the Large Hadron Collider (LHC). TANs are positioned about …
Olivine-rich asteroids in the near-Earth space
M. Popescu, D. Perna, M. A. Barucci +6
In the framework of a 30-night spectroscopic survey of small near-Earth asteroids (NEAs) we present new results regarding the identification of olivine-rich objects. The following…
An investigation of the low-DeltaV near-Earth asteroids (341843) 2008 EV5 and (52381) 1993 HA. Two suitable targets for the ARM and MarcoPolo-M5 space missions
D. Perna, M. Popescu, F. Monteiro +3
The Asteroid Redirect Mission (ARM) under development by NASA is being planned to collect a multi-meter boulder from a near-Earth asteroid (NEA), and to bring it to the cis-lunar s…
