Added 9 e- of postflash to the F438W frames that haven't yet executed. If the 20 second visibility overrun that this causes turns out to be a problem, the best solution is probably to shave the F606W exposure times. -1782687189 ----- Attempting Submission 2 (Mon Aug 26 03:43:16 GMT 2013) ----- ----- Attempting Submission 3 (Tue Dec 17 14:37:35 GMT 2013) ----- Visibility overrun caused by additional overhead from post-flash. It doesn't actually happen during an exposure, just during the last readout, so it might be OK. If it's not, then we should shrink the F606W frames. Mutual Orbits and Physical Properties of 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 these observations and exploit them to constrain conditions in the protoplanetary disk where they 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, and 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 only the systems where we can obtain a dramatic improvement in orbital knowledge from just one or two visits, and only those where the secondary is too faint to pursue with ground-based near-IR adaptive optics techniques. The goal of this project is to image six 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 or two more epochs are needed to secure their orbits. In the case of systems that need two visits, the second visit is 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.
