Temporal behavior of the SO 1.707 micron ro-vibronic emission band in Io's atmosphere

Conor Laver, Imke de Pater, Henry Roe +1

We report observations of the ro-vibronic transition of SO at 1.707 microns on Io. These data were taken while Io was eclipsed by Jupiter, on four nights between July 2000 and Marc…

Direct measurement of the size of 2003 UB313 from the Hubble Space Telescope

M. E. Brown, E. L. Schaller, H. G. Roe +2

We have used the Hubble Space Telescope to directly measure the angular size of the large Kuiper belt object 2003 UB313. By carefully calibrating the point spread function of a nea…

Photometric Observations Constraining the Size, Shape, and Albedo of 2003 El61, a Rapidly Rotating, Pluto-Sized Object in the Kuiper Belt

David L. Rabinowitz, Kristina Barkume, Michael E. Brown +4

We present measurements at optical wavelengths of the spectral reflectance, rotational light curve, and solar phase curve of 2003 EL61. With apparent visual magnitude 17.5 at 51 AU…

Implications of Atmospheric Differential Refraction for Adaptive Optics Observations

Henry G. Roe

Many adaptive optics systems operate by measuring the distortion of the wavefront in one wavelength range and performing the scientific observations in a second, different waveleng…

NOTE: Titan's Atmosphere in Late Southern Spring Observed with Adaptive Optics on the W.M. Keck II 10-meter Telescope

Henry G. Roe, Imke de Pater, Bruce A. Macintosh +3

Using adaptive optics on the W.M. Keck II telescope we imaged Titan several times during 1999 to 2001 in narrowband near-infrared filters selected to probe Titan's stratosphere and…

The Altitude of an Infrared Bright Cloud Feature on Neptune from Near-Infrared Spectroscopy

Henry G. Roe, James R. Graham, Ian S. McLean +8

We present 2.03-2.30 micron near-infrared spectroscopy of Neptune taken 1999 June 2 (UT) with the W.M. Keck Observatory's near-infrared spectrometer (NIRSPEC) during the commission…
