FOSSIL. I. The Spin Rate Limit of Jupiter Trojans
نویسندگان
چکیده
Abstract Rotation periods of 53 small (diameters 2 km < D 40 km) Jupiter Trojans (JTs) were derived using the high-cadence lightcurves obtained by FOSSIL phase I survey, a Subaru/Hyper Suprime-Cam intensive program. These are first reported measured for JTs with 10 km. We found lower limit rotation period near 4 hr, instead previously published result 5 hr larger JTs. Assuming rubble-pile structure JTs, bulk density ≈0.9 g cm −3 is required to withstand this spin rate limit, consistent value ∼0.8–1.0 from binary JT system, (617) Patroclus–Menoetius system.

The Color–magnitude Distribution of Small Jupiter Trojans
We present an analysis of survey observations targeting the leading L4 Jupiter Trojan cloud near opposition using the wide-field Suprime-Cam CCD camera on the 8.2 m Subaru Telescope. The survey covered about 38 deg of sky and imaged 147 fields spread across a wide region of the L4 cloud. Each field was imaged in both the g′ and the i′ band, allowing for the measurement of g − i color. We detect...
متن کاملA Hypothesis for the Color Bimodality of Jupiter Trojans
One of the most enigmatic and hitherto unexplained properties of Jupiter Trojans is their bimodal color distribution. This bimodality is indicative of two sub-populations within the Trojans, which have distinct size distributions. In this paper, we present a simple, plausible hypothesis for the origin and evolution of the two Trojan color sub-populations. In the framework of dynamical instabili...
متن کاملDynamics of Jupiter Trojans during the 2:1 mean motion resonance crossing of Jupiter and Saturn
In the early phase of the Solar System evolution, while the outer planets migrated due to their interaction with a planetesimal disk, Jupiter may have crossed the 2:1 mean motion resonance with Saturn. It is well known (Morbidelli et al. 2005) that this dynamical event has profound consequences on the evolution of an alleged initial Trojan population of Jupiter. In this paper, we analyse in det...
متن کاملConsiderations on the magnitude distributions of the Kuiper belt and of the Jupiter Trojans
By examining the absolute magnitude (H) distributions (hereafter HD) of the cold and hot populations in the Kuiper belt and of the Trojans of Jupiter, we find evidence that the Trojans have been captured from the outer part of the primordial trans-Neptunian planetesimal disk. We develop a sketch model of the HDs in the inner and outer parts of the disk that is consistent with the observed distr...
متن کاملThe observed Trojans and the global dynamics around the Lagrangian points of the Sun–Jupiter system
In this paper, we make a systematic study of the global dynamical structure of the Sun– Jupiter L4 tadpole region. The results are based on long-time simulations of the Trojans in the Sun, Jupiter, Saturn system and on the frequency analysis of these orbits. We give some initial results in the description of the resonant structure that guides the long-term dynamics of this region. Moreover, we ...
