Spectroscopic observations of Jupiter Trojans

Icarus, 2004
Abstract We present the results of a campaign of spectroscopic observations of Jupiter Trojan asteroids. Thirty-four objects were observed during three runs in July and November 1998, and March 2002 using the Danish 1.54-m telescope at ESO. The covered spectral range was between 5000 and 9000 A.

Capture of Trojans by a Growing Proto-Jupiter

Icarus, 1998
Abstract We have studied the capture of planetesimals in Trojan orbits by a growing proto-Jupiter by integrating numerically the equations of motion of planetesimals in a four-body problem Sun–Jupiter–Saturn–planetesimal. The masses of Jupiter and Saturn increase exponentially with time.

Lightcurves of 6 Jupiter Trojan asteroids

Planetary and Space Science, 2010
Abstract From the point of view of the intrinsic rotation, the Jupiter Trojans are not as well characterized as the main belt asteroids, primarily because the available sample of lightcurves is small and mainly restricted to the largest objects. We have obtained rotational periods and lightcurve amplitudes for 6 Trojan asteroids, which range between ...

Total mass of the Jupiter Trojans

Solar System Research, 2015
The total mass of the Jupiter Trojans is estimated at (0.30 ± 0.19) × 10–10MSun using all available physical characteristics of these asteroids. The mass of asteroids in the L4 swarm ((0.19 ± 0.11) × 10–10MSun) is higher than that in the L5 swarm ((0.11 ± 0.07) × 10–10MSun) by a factor of 1.7. The obtained estimates include the hidden mass of asteroids

Dynamical evolution of Jupiter's Trojan asteroids

Nature, 1997
TROJAN asteroids, which may outnumber the asteroids in the asteriod belt, are objects that orbit the Sun with the same mean semi-major axis as Jupiter, but lead or trail the position of Jupiter in its orbit by ˜60°. One very interesting aspect of the Trojan swarms is that a significant number of asteroids are on orbits that analytic theory suggests ...

Jupiter’s Trojans: Physical properties and origin

Solar System Research, 2014
The current concepts on the physical properties of the Jovian Trojans are reviewed in the paper. The distributions of rotation periods and light-curve amplitudes, the features of the phase dependencies of brightness, and the available data on the surface composition, density, diameters, and albedo of the Trojans are analyzed.

On the Instability of Jupiter's Trojans

Icarus, 2002
Abstract We have numerically explored the mechanisms that destabilize Jupiter's Trojan orbits outside the stability region defined by Levison et al. (1997, Nature 385 , 42–44). Different models have been exploited to test various possible sources of instability on timescales on the order of ∼10 8 years.

Missions to the Jupiter Trojans

40th International Conference on Environmental Systems, 2010
During the last French prospective Conference in Biarritz, in early 2009, a fly-by mission to the Jupiter Trojans was proposed by the European scientific community. The asteroids population situated at the Jupiter Lagrange points L4 and L5 , (i.e. 60 degrees backwards and forward from Jupiter’s orbit), is not well known. Their study by low distance fly-

Masses of the Trojan Groups of Jupiter

Astronomy Letters, 2019
The possibility of obtaining dynamical estimates of the total masses in the two Trojan asteroid groups of Jupiter is investigated. The compact Greek (L4) and Trojan (L5) groups contain several tens of thousands of asteroids near the stable Lagrange points moving in a 1: 1 resonance with the orbital motion of Jupiter.
