Spectral Evidence for a Brucite-carbonate Alteration Assemblage on Ceres

Introduction: The dwarf planet Ceres is the largest object in the asteroid belt and is a primary target of NASA’s Dawn mission [1]. Recent modeling has shown that Ceres is likely differentiated and consists of a thin silicate+ice crust underlain by a thicker water ice mantle [2,3]. The presence of hydrated phases on Ceres, as inferred from the 3 μm absorption feature present in surface reflecta...

Electron Cyclotron Heating in the Constance 2 Mirror Experiment* Electron Cyclotron Heating in the Constance 2 Mirror Experiment

Electron cyclotron heating of a highly-ionized plasma in mirror geomctry is investigated. Of primary interest is the experimental diagnosis of the elcctron energy distribution and the comparison of the results of this diagnosis with a two dimensional, time-dependent Fokkcr-Planck simulation. 'Tliese two goals are accomplished in four steps. (1) First, the power balance of the heated and unheate...

Inter­calated brucite-type layered cobalt(II) hydroxy­sulfate

In an attempt to synthesize new cobalt(II) sulfate framework structures using 1,4-diaza-bicyclo-[2.2.2]octane as a template, crystals of poly[0.35-[hexa-aqua-cobalt(II)] [tri-μ-hydroxido-μ-sulfato-dicobalt(II)]], {[Co(H(2)O)(6)](0.35)[Co(2)(OH)(3)(SO(4))]}(n), were obtained as a mixture with [Co(H(2)O)(6)]SO(4) crystals. The crystal structure can be described as being constructed from discrete ...
