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…
The Physical Properties and Effective Temperature Scale of O-type Stars as a Function of Metallicity. III. More Results from the Magellanic Clouds
Philip Massey, Amanda M. Zangari, Nidia I. Morrell +4
In order to better determine the physical properties of hot, massive stars as a function of metallicity, we obtained very high SNR optical spectra of 26 O and early B stars in the…
The Highly Eccentric Pre-Main Sequence Spectroscopic Binary RX J0529.3+1210
G. N. Mace, L. Prato, L. H. Wasserman +3
The young system RX J0529.3+1210 was initially identified as a single-lined spectroscopic binary. Using high-resolution infrared spectra, acquired with NIRSPEC on Keck II, we measu…
Diameters and albedos of three sub-kilometer Near Earth Objects derived from Spitzer observations
D. E. Trilling, M. Mueller, J. L. Hora +6
Near Earth Objects (NEOs) are fragments of remnant primitive bodies that date from the era of Solar System formation. At present, the physical properties and origins of NEOs are po…
Orbits and Pulsations of the Classical ζAurigae Binaries
Joel A. Eaton, Gregory W. Henry, Andrew P. Odell
We have derived new orbits for zeta Aur, 32 Cyg, and 31 Cyg with observations from the TSU Automatic Spectroscopic Telescope and used them to identify non-orbital velocities of the…
The Age of Cluster Galaxies from Continuum Colors
K. Rakos, J. Schombert, A. Odell
We determine the age of 1,104 early-type galaxies in eight rich clusters ( to ) using a new continuum color technique. We find that galaxies in clusters divide i…
