Absolute Doubly Differential Angular Sputtering Yields for 20 keV Kr+ on Polycrystalline Cu

Caixia Bu, Liam S. Morrissey, Benjamin C. Bostick +16

We have measured the absolute doubly differential angular sputtering yield for 20 keV Kr+ impacting a polycrystalline Cu slab at an incidence angle of θi = 45° relative to the surf…

Djerfisherite: Nebular Source of Refractory Potassium

Denton S. Ebel, Richard O. Sack

Djerfisherite is an important carrier of potassium in highly reduced enstatite chondrites, where it occurs in sub-round metal-sulfide nodules. These nodules were once free-floating…

Laser Scanning Confocal Microscopy of Comet Material in Aerogel

Michael Greenberg, Denton S. Ebel

We report non-destructive 3-dimensional imaging and analysis techniques for material returned by the Stardust cometary collector. Our technique utilizes 3-dimensional laser scannin…

Equilibrium Condensation from Chondritic Porous IDP Enriched Vapor: Implications for Mercury and Enstatite Chondrite Origins

Denton S. Ebel, Conel M. O'D. Alexander

The origin of Mercury's anomalous core and low FeO surface mineralogy are outstanding questions in planetary science. Mercury's composition may result from cosmochemical controls o…

The Origin of Chondrules: Constraints from Matrix-Chondrule Complementarity

Herbert Palme, Dominik C. Hezel, Denton S. Ebel

One of the major unresolved problems in cosmochemistry is the origin of chondrules, once molten, spherical silicate droplets with diameters of 0.2 to 2 mm. Chondrules are an essent…

Experimental Investigation of Condensation Predictions for Dust-Enriched Systems

Gokce Ustunisik, Denton S. Ebel, David Walker +1

Condensation models describe the equilibrium distribution of elements between coexisting mineral solid solutions, silicate liquid, and vapor in a closed chemical system, vapor phas…
