GO 10512: A search for Binaries Among Faint Jupiter Trojan Asteroids
An artist's impression of the binary asteroid, Patroclus | Binary stars have been known for well over 300 years, but it is only within the last decade that it has been clear that asteroids are also often found in pairs. This is somewhat unexpected, since the low mass of asteroids leads to very low binding energy between the components. Both the formation mechanism(s?) and the stability of current systems remain unclear. The present program is using the HRC on ACS to carry out a snapshot survey of faint Trojan asteroids, which reside at the stable L4 and L5 Lagrange points on Jupiter's orbit. Several larger Trojans are known to be binary (e.g. Patroclus, see this link for more information), but data remain spare for the fainter members of this population. The collision environment among the Trojans is similar to that of Main Belt asteroids, but the composition is likely to be very different; thus, sampling the binary fraction over a significant range in mass should help us understand the relative importance of collisional and binary formation mechanisms. |
