Titan: High-Resolution Speckle Images from the Keck Telescope
Abstract Saturn's large moon Titan is unique among planetary satellites in that it possesses a thick atmosphere and a haze layer that is opaque to visible light. This haze is believed to be composed…
Generation of lightning in Jupiter's water cloud
This model predicts that a condensed-water abundance in the range of at least 1-2 g m–3 is required for lightning to occur in jovian thunderstorms—a prediction that may be tested when the Galileo probe arrives at Jupiter on 7 December 1995.

The dynamic neptunian ring arcs: evidence for a gradual disappearance of Liberté and resonant jump of courage
Speckle Imaging of Titan at 2 microns: Surface Albedo,Haze Optical Depth, and Tropospheric Clouds 1996-1998
Titan's 2 μm surface albedo and haze optical depth in 1996–2004
We observed Titan in 1996–2004 with high‐resolution 2 μm speckle and adaptive optics imaging at the W. M. Keck Observatory. By observing in a 2 μm broadband filter we obtain images that have…
ON THE POSSIBILITY OF LIGHTNING IN THE PROTOSOLAR NEBULA
Abstract Chondrules constitute a significant fraction of primitive meteorites. Their thermal history includes rapid melting followed by cooling on timescales of minutes to hours. The mechanism…

New Dust Belts of Uranus: One Ring, Two Ring, Red Ring, Blue Ring
Near-infrared observations of the recently discovered outer rings of Uranus are compared with Hubble Space Telescope results, and it is found that the inner ring, R/2003 U 2, is red, whereas the outer ring,R/ 2003 U 1, is very blue.
