Mutual Orbits and Masses of Six Transneptunian Binaries
W. M. Grundy, K. S. Noll, M. W. Buie +3
We present Hubble Space Telescope observations of six binary transneptunian systems: 2000 QL251, 2003 TJ58, 2001 XR254, 1999 OJ4, (134860) 2000 OJ67, and 2004 PB108. The mutual orb…
The Correlated Colors of Transneptunian Binaries
S. D. Benecchi, K. S. Noll, W. M. Grundy +3
We report resolved photometry of the primary and secondary components of 23 transneptunian binaries obtained with the Hubble Space Telescope. V-I colors of the components range fro…
Digging Into the Surface of the Icy Dwarf Planet Eris
M. R. Abernathy, S. C. Tegler, W. M. Grundy +4
We describe optical spectroscopic observations of the icy dwarf planet Eris with the 6.5 meter MMT telescope and the Red Channel Spectrograph. We report a correlation, that is at t…
(42355) Typhon-Echidna: Scheduling Observations for Binary Orbit Determination
W. M. Grundy, K. S. Noll, J. Virtanen +6
We describe a strategy for scheduling astrometric observations to minimize the number required to determine the mutual orbits of binary transneptunian systems. The method is illust…
Masses of Nix and Hydra
David J. Tholen, Marc W. Buie, William M. Grundy +1
A four-body orbit solution for the Pluto system yields GM values of 870.3 +/- 3.7, 101.4 +/- 2.8, 0.039 +/- 0.034, and 0.021 +/- 0.042 km3 sec-2 for Pluto, Charon, Nix, and Hydra,…
Evidence for Two Populations of Classical Transneptunian Objects: The Strong Inclination Dependence of Classical Binaries
Keith S. Noll, William M. Grundy, Denise C. Stephens +2
We have searched 101 Classical transneptunian objects for companions with the Hubble Space Telescope. Of these, at least 21 are binary. The heliocentric inclinations of the objects…
