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…
High Albedos of Low Inclination Classical Kuiper Belt Objects
M. J. Brucker, W. M. Grundy, J. A. Stansberry +4
We present observations of thermal emission from fifteen transneptunian objects (TNOs) made using the Spitzer Space Telescope. Thirteen of the targets are members of the Classical…
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…
Pluto's Light Curve in 1933-1934
Bradley E. Schaefer, Marc W. Buie, Luke Timothy Smith
We are reporting on a new accurate photographic light curve of Pluto for 1933-1934 when the heliocentric distance was 40 AU. We used 43 B-band and V-band images of Pluto on 32 plat…
Distributions of H2O and CO2 ices on Ariel, Umbriel, Titania, and Oberon from IRTF/SpeX observations
W. M. Grundy, L. A. Young, J. R. Spencer +3
We present 0.8 to 2.4 micron spectral observations of uranian satellites, obtained at IRTF/SpeX on 17 nights during 2001-2005. The spectra reveal for the first time the presence of…
Spitzer/IRAC and JHKs Observations of h & chi Persei: Constraints on Protoplanetary Disk and Massive Cluster Evolution at ~ 10^{7} yr
Thayne Currie, Zoltan Balog, S. J. Kenyon +12
We describe IRAC 3.6-8 mu_m observations and ground-based near-IR JHKs photometry from Mimir and 2MASS of the massive double cluster h & chi Persei complete to J=15.5 (M ~ 1.3 Msun…
