A homogeneous nucleus for comet 67P/Churyumov–Gerasimenko from its gravity field
TLDR
It is concluded that the interior of the nucleus of comet 67P/Churyumov–Gerasimenko is homogeneous and constant in density on a global scale without large voids. Expand
Dust measurements in the coma of comet 67P/Churyumov-Gerasimenko inbound to the Sun
TLDR
The largest orbiting clumps are meter-sized, confirming the dust/gas ratio of 3 inferred at perihelion from models of dust comae and trails. Expand
The size distribution of Jupiter Family comet nuclei
We present an updated cumulative size distribution (CSD) for Jupiter Family comet (JFC) nuclei, including a rigorous assessment of the uncertainty on the slope of the CSD. The CSD is expressed as aExpand
Structure and density of cometary nuclei
Understanding the nature of the cometary nucleus remains one of the major problems in solar system science. Whipples (1950) icy conglomerate model has been very successful at explaining a range ofExpand
Centaurs and Scattered Disk Objects in the Thermal Infrared: Analysis of WISE/NEOWISE Observations
The Wide-field Infrared Survey Explorer (WISE) observed 52 Centaurs and scattered disk objects (SDOs) in the thermal infrared, including 15 new discoveries. We present analyses of these observationsExpand
Density and Charge of Pristine Fluffy Particles from Comet 67P/Churyumov-Gerasimenko
The Grain Impact Analyzer and Dust Accumulator (GIADA) instrument on board ESA’s Rosetta mission is constraining the origin of the dust particles detected within the coma of comet 67Expand
Near-Infrared Mapping Spectrometer experiment on Galileo
The Galileo Near-Infrared Mapping Spectrometer (NIMS) is a combination of imaging and spectroscopic methods. Simultaneous use of these two methods yields a powerful combination, far greater than whenExpand
Stellar encounters with the solar system
We continue our search, based on Hipparcos data, for stars which have encountered or will encounter the solar system (Garcia-Sanchez et al. [CITE]). Hipparcos parallax and proper motion data areExpand
Comet 67P/Churyumov-Gerasimenko preserved the pebbles that formed planetesimals
Solar System formation models predict that the building-blocks of planetesimals were mm- to cm-sized pebbles, aggregates of ices and non-volatile materials, consistent with the compact particlesExpand
A collision in 2009 as the origin of the debris trail of asteroid P/2010 A2
TLDR
It is determined that this was an asteroid collision that occurred around 10 February 2009 and can be explained by an initial impact ejecting large clumps of debris that disintegrated and dispersed almost immediately. Expand
