Moving mountains and white spots of Ceres
@article{Gur2017MovingMA, title={Moving mountains and white spots of Ceres}, author={A. Soumbatov Gur}, journal={arXiv: General Physics}, year={2017} }
Among surprising results of NASA's Dawn spacecraft mission at dwarf planet Ceres are enigmatic bright spots inside Occator crater and a lone tall pyramid mountain. Here we explain the appearance of such spots, weird mountains, and concomitant craters on celestial bodies. The phenomenon is as follows. A mountain is ejected rotated out of mechanically stressed crust as a result of explosive conical cleavage all over its buried surface. Then the mountain lands upside down i.e. summit up. It may…

Cryovolcanism on Ceres
- GeologyScience
- 2016
It is proposed that hydrated salts with low eutectic temperatures and low thermal conductivities enabled the presence of cryomagmatic liquids within Ceres, a key process for Ceres’ evolution as recorded by the aqueously altered, secondary minerals observed on the surface.

It is concluded that Ceres must have accreted material from beyond the ‘snow line’, which is the distance from the Sun at which water molecules condense, and is consistent with hydrated magnesium sulfates mixed with dark background material.

C Ceres’ dry exterior displays hydroxylated silicates, including ammoniated clays of endogenous origin, which suggest a mechanically strong lithosphere with a weaker deep interior.

Ceres is the largest body in the asteroid belt with a radius of approximately 470 km. In part due to its large mass, Ceres more closely approaches hydrostatic equilibrium than major asteroids.…
The geomorphology of Ceres
- GeologyScience

The global trend of lobate flows suggests that differences in their geomorphology could be explained by variations in ice content and temperature at the near surface, and the identification of these potentially ice-related features suggests that there may be more ice within localized regions of Ceres’ crust.

The detection of water vapour around Ceres is reported, with at least 1026 molecules being produced per second, originating from localized sources that seem to be linked to mid-latitude regions on the surface.
Ammoniated phyllosilicates with a likely outer Solar System origin on (1) Ceres
- Geology, PhysicsNature
- 2015
Measurements of Ceres indicate widespread ammoniated phyllosilicates across the surface, but no detectable water ice, which suggests that material from the outer Solar System was incorporated into Ceres, either during its formation at great heliocentric distance or by incorporation of material transported into the main asteroid belt.

The widespread presence of these two types of minerals is a strong indication of a global and extensive aqueous alteration—i.e., the presence of water at some point in Ceres’ geological history.
