Solar system: Evaporating asteroid

  title={Solar system: Evaporating asteroid},
  author={Humberto Campins and Christina M. Comfort},
The asteroid Ceres has been thought to contain abundant water. Observations acquired with the Herschel Space Observatory now show that this Solar System object is spewing water vapour from its surface. See Letter p.525 


Asteroid 1 Ceres - Evidence for water of hydration
An absorption feature centred near 3.0 microns has been discovered in the infrared spectrum of asteroid 1 Ceres. This spectrum has been compared with laboratory spectra of meteorites and shows great
Localized sources of water vapour on the dwarf planet (1) Ceres
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.
A Jupiter-mass companion to a solar-type star
The presence of a Jupiter-mass companion to the star 51 Pegasi is inferred from observations of periodic variations in the star's radial velocity. The companion lies only about eight million
Detection of ice and organics on an asteroidal surface
The spectroscopic detection of water ice and organic material on the asteroid 24 Themis is reported, a detection that has been independently confirmed and concludes that water ice is more common on asteroids than was previous thought and may be widespread in asteroidal interiors at much smaller heliocentric distances than was previously expected.
Water ice and organics on the surface of the asteroid 24 Themis
Infrared spectra of the asteroid 24 Themis show that ice and organic compounds are not only present on its surface but also prevalent, and their identification agrees with independent results that rule out other compounds as possible sources of the observed spectral structure.
Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System.
Ceres: Evolution and current state
[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
Chaotic capture of Jupiter's Trojan asteroids in the early Solar System
It is shown that the Trojans could have formed in more distant regions and been subsequently captured into co-orbital motion with Jupiter during the time when the giant planets migrated by removing neighbouring planetesimals.
Populating the asteroid belt from two parent source regions due to the migration of giant planets—"The Grand Tack"
Abstract– The asteroid belt is found today in a dramatically different state than that immediately following its formation. It is estimated that it has been depleted in total mass by a factor of at
