Activities for July, 2017

Saturday, July 8, 2017

Dr. Audrey Thirouin, Lowell Observatory

Title: “Contact Binary in the Trans-Neptunian Belnomy”

A contact binary is a system of two separated objects almost in contact, but it can also be an object consisting of two lobes in contact (bi-lobed object with a peanut/bone shape). This kind of peculiar system/object is found across all the small body populations in our Solar System, from the Near-Earth Objects population to the Trans-Neptunian belt.

Contact binaries in the Trans-Neptunian belt are not resolvable with the Hubble Space Telescope because of the small separation between the system's components. Only light curves with a characteristic V-shape/U-shape at the minimum/maximum of brightness and a large amplitude can identify these objects. Despite an expected high fraction of contact binaries, so far only one has been found in the Trans-Neptunian belt. If the contact binaries are so common, where are they?
