“…The VIS spectrum of 4055 Magellan exhibits a very deep 1-µm absorption band characteristic of pyroxene assemblages (e.g., Cloutis and Gaffey, 1991;Gaffey et al, 2002;Moskovitz et al, 2010). Our classification of this asteroid as a V-type is consistent with previous studies (Lazzaro et al, 2004;Binzel et al, 2004 (Bus) of the observed asteroids. The measured spectral slope for each asteroid is given.…”

“…These objects have been observed and classified by previous studies (Bus and Binzel, 2002a,b;Lazzaro et al, 2004;Binzel et al, 2004). Discrepancies between the taxonomic classification assigned by us and that by previous work were found for two of the asteroids (1656 Suomi and 5407).…”

“…In the case of asteroid 5407 it was classified by us as S-type, while Bus and Binzel (2002a,b) classified it as Sk (same complex, different subtype). Figure 4 shows the spectra of asteroid (1656) Suomi and 5407 compared with those obtained by Lazzaro et al (2004) and Bus and Binzel (2002a,b), respectively. As noted by Bus et al (2002), these kind of discrepancies are often reported when the spectra of asteroids observed by different surveys are compared.…”

“…According to our results asteroid (1656) Suomi belongs to the S-complex, however due to the scattering in the data beyond 0.8 µm we were not able to establish its subtype within the S-complex. Lazzaro et al (2004) classified this asteroid as Ld. In the case of asteroid 5407 it was classified by us as S-type, while Bus and Binzel (2002a,b) classified it as Sk (same complex, different subtype).…”

In the past, constraining the surface composition of near-Earth asteroids (NEAs) has been difficult due to the lack of high quality near-IR spectral data (0.7-2.5 µm) that contain mineralogically diagnostic absorption bands. Here we present visible (∼ 0.43-0.95 µm) and nearinfrared (∼ 0.7-2.5 µm) spectra of nine NEAs and five Mars-crossing asteroids (MCs). The YT1) as a V-type was made on the basis of its near-infrared spectrum since no visible spectrum is available for this asteroid. A mineralogical analysis was performed on six of the asteroids (those for which near-IR spectra were obtained or previously available). We found that three asteroids (241662 (2000 KO44), 19764 (2000 NF5), 138404 (2000) have mafic silicate compositions consistent with ordinary chondrites, while three others (4055 Magellan, 164121 (2003 YT1), 5407 (1992 AX)) are pyroxene-dominated basaltic achondrite assemblages. In the case of 5407 (1992 AX) we found that its basaltic surface composition contrasts its taxonomic classification as a S-type.

Creation, detection, and evolution of Jupiter Trojan families

An investigation is carried out looking at correlations between the orbital elements of collisional targets and projectiles, estimating the number of interlopers in Trojan collisional families, and at the possibility of determining the ages of the Jupiter Trojan families by orbital integration. Real Trojans are integrated and close encounters are recorded in order to evaluate collisional circumstances between Trojans. Fictitious collisional families are created and integrated for 10 MJyr (million Julian years) forward in time and back again to the time of the collision in order to check the performance of the integrator, and the behaviour of the fictitious collisional fragments. Proper elements are calculated for the detection of family clustering using the hierarchically clustering method. This method presents little difficulty finding fictitious families in the Trojan swarms even in areas with densely populated backgrounds. However, even when the background is relatively sparse in objects, several interlopers can be connected to the family at velocity differences below 100 m s −1 . On the other hand, in densely populated backgrounds the contamination of interlopers should be less than 30 %. Providing gravity is the only significant force acting on the Trojans and resonance effects are weak, the shape the collision fragments create in the proper element space are preserved on the GJyr scale, and collisions can be tracked with orbital integrations for ages of at least 100 MJyr. However, the shape of artificial families does not correspond to suggested real families. This points to the need of including non-gravitational forces such as the Yarkovsky effect in order to simulate the family evolution. As a consequence age determination by orbital integration might be severely restricted and previous investigations involving long term orbital integrations might have to be recalculated.
