Ceres: Evolution and current state

  title={Ceres: Evolution and current state},
  author={Thomas B. McCord and Christophe Sotin},
  journal={Journal of Geophysical Research},
[1] We modeled several thermal evolution scenarios for Ceres to explore the nature of large, wet protoplanets and to predict current-day evidence that might be found by close inspection, such as by the Dawn mission. The density for Ceres is near 2.1, suggesting a water content between 17% and 27% by mass. Short- and long-lived radioactive nuclide heating is considered. Even if only long-lived radionuclide heating is assumed, the water ice in Ceres melts quickly and a water mantle forms, but an… Expand
Geochemistry, thermal evolution, and cryovolcanism on Ceres with a muddy ice mantle
We present a model of the internal evolution of Ceres consistent with pre-Dawn observations and preliminary data returned by Dawn. We assume that Ceres accreted ice and both micron- andExpand
Ceres: Predictions for near-surface water ice stability and implications for plume generating processes
This paper will constrain the possible sources and processes for the formation of recently observed H2O vapor plumes above the surface of the dwarf planet Ceres. Two hypotheses have been proposed:Expand
Ceres’ partial differentiation: undifferentiated crust mixing with a water-rich mantle
Aims. We model thermal evolution and water-rock differentiation of small ice-rock objects that accreted at different heliocentric distances, while also considering migration into the asteroid beltExpand
Ceres internal structure from geophysical constraints
Thermal evolution modeling has yielded a variety of interior structures for Ceres, ranging from a modestly differentiated interior to more advanced evolution with a dry silicate core, a hydratedExpand
Predicted crater morphologies on Ceres: Probing internal structure and evolution
The detailed internal structure of the dwarf planet Ceres, target of NASA’s Dawn mission, has not been unequivocally determined from ground-based data. Whereas Ceres is most likely differentiatedExpand
Extensive water ice within Ceres’ aqueously altered regolith: Evidence from nuclear spectroscopy
Nuclear spectroscopy data acquired by NASA’s Dawn mission determined the concentrations of elemental hydrogen, iron, and potassium on Ceres, and show that surface materials were processed by the action of water within the interior, confirming theoretical predictions that ice can survive for billions of years just beneath the surface.

Thermal convection in the crust of the dwarf planet – I. Ceres
Ceres is the largest body in the Main Belt, and it is characterized by a large abundance of water ice in its interior. This feature is suggested by its relatively low bulk density (2162 kg m$^{-3}$),Expand
Ceres’ evolution and present state constrained by shape data
We model Ceres’ thermo-physical-chemical evolution by considering a large range of initial conditions as well as various evolutionary scenarios. Models are constrained by available shapeExpand
Oxo Crater on (1) Ceres: Geological History and the Role of Water-ice
Dwarf planet Ceres (empty set similar to 940 km) is the largest object in the main asteroid belt. Investigations suggest that Ceres is a thermally evolved, volatile-rich body with potentialExpand
Core cracking and hydrothermal circulation can profoundly affect Ceres' geophysical evolution
Observations and models of Ceres suggest that its evolution was shaped by interactions between liquid water and silicate rock. Hydrothermal processes in a heated core require both fractured rock andExpand


The water regime of asteroid (1) Ceres
Abstract An analytical model is presented which describes the water regime of asteroid Ceres. The model predicts surface and subsurface temperatures, water fluxes, and ice depths as well asExpand
Internal structure and dynamics of the large icy satellites
Abstract The magnetic data returned by the Galileo mission suggest that deep oceans are present within the icy Galilean satellites. In addition, tectonic features on Europa are consistent with modelsExpand
Importance of the accretion process in asteroid thermal evolution: 6 Hebe as an example
Widespread evidence exists for heating that caused melting, thermal metamorphism, and aqueous alteration in meteorite parent bodies. Previous simulations of asteroid heat transfer have assumed thatExpand
Thermal convection in the outer shell of large icy satellites
Evolution of large icy satellites is controlled by heat transfer across the outer ice I layer. After the core overturn a possible structure consists of a silicate core and a shell of molten ices. AsExpand
Tidally heated convection: Constraints on Europa's ice shell thickness
[1] The thickness of Europa's ice shell is constrained with numerical experiments of thermal convection, including heterogeneous tidal heating. Thermal convection occurs in the stagnant lid regimeExpand
Gravitational constraints on the internal structure of Ganymede
BEFORE the arrival of the Galileo spacecraft in the jovian system, there was little information on the interior structure of Jupiter's largest moon, Ganymede. Its mean density (1,940 kg m−3),Expand
Water and the thermal evolution of carbonaceous chondrite parent bodies
Many carbonaceous chondrites have been aqueously altered within their parent bodies. From chemical and textural data on these meteorites and from studies of collision mechanics, we pose twoExpand

The distribution of aluminum-26 in the early Solar System—A reappraisal
— A compilation of over 1500 Mg-isotopic analyses of Al-rich material from primitive solar system matter (meteorites) shows clearly that 26Al existed live in the early Solar System. Excesses of 26MgExpand
On the internal structure and dynamics of Titan
Abstract The purpose of this paper is to study the evolution of Titan from the primordial core overturn to the present, and to investigate the possible existence of both a deep liquid layer and anExpand
