It would be nice if it could get scheduled in the May plan window, but early June would be OK, too. 1007346749 ----- Attempting Submission 1 (Tue Jul 22 23:29:01 GMT 2014) ----- ----- Attempting Submission 2 (Wed Mar 11 16:30:15 GMT 2015) ----- ----- Attempting Submission 3 (Sun Apr 26 21:28:44 GMT 2015) ----- Orbits and Physical Properties of Four Binary Transneptunian Objects Intriguing patterns are evident in both the orbits of transneptunian objects and in their observable external characteristics (colors, spectral features, etc.). Bulk physical properties are needed to make sense of the observations and to exploit them to constrain conditions in the protoplanetary disk where these objects formed. The key to obtaining bulk properties of transneptunian objects is that a sizeable proportion of them are binaries. Binary mutual orbits provide dynamical masses that can in turn be used to compute bulk densities. A statistical sample of binary orbits offers powerful constraints on formation mechanisms as well as subsequent evolution. This proposal seeks to continue a multi-year campaign to obtain orbits for as large of a sample of binary transneptunian objects as possible. We seek to make efficient use of HST by targeting four systems where we can obtain a dramatic improvement in orbital knowledge from relatively few, strategically timed visits, and where the secondary is too faint for reliable detection with ground-based near-IR adaptive optics techniques. The goal of this project is to image four kuiper belt binary systems at strategic times for purposes of determining their mutual orbits. All of these systems have been observed before, so only one to three more epochs are needed to secure their orbits. In the case of systems that need more than one visit, the later visits are marked as being on hold. The point of this is to wait until the results of the first visit are available and processed in order to determine optimal time windows for the second visit. This program is functionally identical to program 13404 from Cycle 21.
