Basaltic material in the main belt: a tale of two (or more) parent bodies?
S. Ieva, E. Dotto, D. Lazzaro +5
The majority of basaltic objects in the main belt are dynamically connected to Vesta, the largest differentiated asteroid known. Others, due to their current orbital parameters, ca…
Photometric survey of 67 near-Earth objects
S. Ieva, E. Dotto, E. Mazzotta Epifani +9
The near-Earth object (NEO) population is a window into the original conditions of the protosolar nebula, and has the potential to provide a key pathway for the delivery of water a…
A spectroscopic survey of the small near-Earth asteroid population: peculiar taxonomic distribution and phase reddening

We present the first-ever rotationally resolved spectroscopic investigation of (624) Hektor and (911) Agamemnon, the two largest Jupiter Trojans. The visible and near-infrared spec…
Photometric observations of nine Transneptunian objects and Centaurs
T. Hromakina, D. Perna, I. Belskaya +3
We present the results of photometric observations of six Transneptunian objects and three Centaurs, estimations of their rotational periods and corresponding amplitudes. For six o…

P. Santos-Sanz, E. Lellouch, O. Groussin +10
Time series observations of the dwarf planet Haumea and the Plutinos 2003VS2 and 2003AZ84 with Herschel/PACS are presented in this work. Thermal emission of these trans-Neptunian o…
Decimetre-scaled spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
C. Feller, S. Fornasier, P. H. Hasselmann +43
We present the results of the photometric and spectrophotometric properties of the 67P/Churyumov-Gerasimenko nucleus derived with the OSIRIS instrument during the closest fly-by ov…
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…
Detection of exposed HO ice on the nucleus of comet 67P/Churyumov-Gerasimenko
M. A. Barucci, G. Filacchione, S. Fornasier +42
Since the orbital insertion of the Rosetta spacecraft, comet 67P/Churyumov-Gerasimenko (67P/C-G) has been mapped by OSIRIS camera and VIRTIS spectro-imager, producing a huge quanti…
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…
