On the nucleus structure and activity of comet 67P/Churyumov-Gerasimenko

Holger Sierks, +70 more
- 23 Jan 2015 - 
TL;DR: Images from the OSIRIS scientific imaging system onboard Rosetta show that the nucleus of 67P/Churyumov-Gerasimenko consists of two lobes connected by a short neck, which raises the question of whether the two Lobes represent a contact binary formed 4.5 billion years ago, or a single body where a gap has evolved via mass loss.
Journal ArticleDOI

The morphological diversity of comet 67P/Churyumov-Gerasimenko

TL;DR: Images of comet 67P/Churyumov-Gerasimenko acquired by the OSIRIS imaging system onboard the European Space Agency’s Rosetta spacecraft offer some support for subsurface fluidization models and mass loss through the ejection of large chunks of material.
Journal ArticleDOI

Large heterogeneities in comet 67P as revealed by active pits from sinkhole collapse

Jean-Baptiste Vincent, +67 more
- 02 Jul 2015 - 
TL;DR: It is reported that pits on comet 67P/Churyumov–Gerasimenko are active, and probably created by a sinkhole process, possibly accompanied by outbursts, and argued that after formation, pits expand slowly in diameter, owing to sublimation-driven retreat of the walls.
Journal ArticleDOI

Two independent and primitive envelopes of the bilobate nucleus of comet 67P

Matteo Massironi, +59 more
- 15 Oct 2015 - 
TL;DR: The notable structural similarities between the two lobes of comet 67P/Churyumov–Gerasimenko indicate that the early-forming cometesimals experienced similar primordial stratified accretion, even though they formed independently.
Journal ArticleDOI

Detection of exposed H2O ice on the nucleus of comet 67P/Churyumov-Gerasimenko - as observed by Rosetta OSIRIS and VIRTIS instruments

TL;DR: In this paper, the authors search for the presence of H 2 O on the nucleus of the comet 67P/Churyumov-Gerasimenko (67P/C-G) by searching for the 2 μm absorption band of water ice in the VIRTIS spectral cubes.
