Habitable zones around main sequence stars.
A one-dimensional climate model is used to estimate the width of the habitable zone (HZ) around our Sun and around other main sequence stars. Our basic premise is that we are dealing with Earth-like… Expand
Turbulence Over Urban-type Roughness: Deductions from Wind-tunnel Measurements
Turbulence data from experiments conducted over a staggered cube array, modelling a neutrally stable atmospheric boundary layer in an urban environment, are presented. The results support the… Expand
Measurements in an urban-type boundary layer
Wind tunnel measurements of the boundary layer flow over a very rough surface comprising a staggered array of cubes are presented and discussed. Attention is concentrated on the near-wall region,… Expand
A slightly more massive young Sun as an explanation for warm temperatures on early Mars.

The valley network channels on the heavily cratered ancient surface of Mars suggest the presence of liquid water approximately 3.8 Gyr ago. However, the implied warm climate is difficult to explain… Expand
Europa, tidally heated oceans, and habitable zones around giant planets.

- Advances in space research : the official journal…
Tidal dissipation in the satellites of a giant planet may provide sufficient heating to maintain an environment favorable to life on the satellite surface or just below a thin ice layer. In our own… Expand
The Viscosity of Miranda
Voyager 2 images of Miranda revealed a significant history of geological activity. Overlying an apparently ancient cratered terrain are assemblages of concentric ridges, scarps, and dark banded… Expand
Temperatures within comet nuclei.
We have performed a theoretical study of temperatures beneath the surface of a comet's nucleus. We solve the one-dimensional heat conduction equation for the outer portion of the comet. The upper… Expand
The carbon budget in the outer solar nebula.

Detailed models of the internal structures of Pluto and Charon, assuming rock and water ice as the only constituents, indicate that the mean silicate mass fraction of this two-body system is on the… Expand
Spanwise variations in nominally two-dimensional rough-wall boundary layers
Laboratory experiments have been conducted in two separate boundary layer facilities to investigate steady spanwise variations in mean velocity discovered during studies of developing flows over… Expand
Processing of refractory meteorite inclusions (CAIs) in parent-body atmospheres.

- 1 March 1990
The refractory meteorite inclusions known as CAIs (calcium-aluminum rich inclusions) display melted rims that were produced by thermal events of only a few seconds duration. We show that gas dynamic… Expand
