A Quartet of Known and Suspected Hungaria Binary Asteroids
Abstract
CCD observations at the Palmer Divide Observatory (PDO) were made of four Hungaria asteroids in mid-2010. One of them, 2577 Litva, was a known binary and 2074 Shoemaker was a strong suspect based on earlier observations. (8026) 1991 JA shows indications of being the second member of a suspected new type of binary asteroid characterized by a short period, low amplitude period superimposed on a very long period, high amplitude curve. The fourth object, 20037 Duke, showed no obvious mutual events to indicate a satellite, but shows a weak secondary period of 21.1 h.
