Proposal Title: Arecibo Radar Observations of 18 Near­Earth Asteroids During July­December
2013
ABSTRACT:
We request 80 sessions (153 hours observing + 75 hours setup = 228 hours total) to observe 18 near­Earth
asteroids, 4 of which are likely larger than a kilometer, 7 of which o#er opportunities for shape modeling at high
signal­to­noise ratio (>500/day), a couple of which may be binaries, and a few of which may reveal
non­gravitational perturbations such as the Yarkovsky e#ect. Several objects provide an important discovery space
as they are currently poorly characterized. Our goals include detailed physical characterization, determination of
binarity or multiplicity, orbital refinement, and shape modeling when possible.
