Gas outflow and dust transport of comet 67P/Churyumov–Gerasimenko [PDF]

, 2016
International audienceBecause of the diurnal thermal cycle and the irregular shape of the nucleus, gas outflow of comet 67P/Churyumov–Gerasimenko could be highly anisotropic as indicated by the colliminated dust jet structures on the sunlit side.

COMetary dust TAIL Simulator (COMTAILS): A computer code to generate comet dust tail brightness images

Astronomy & Astrophysics
Context. We present the COMetary dust TAIL Simulator (COMTAILS), a numerical Monte Carlo code to generate images of dust tail brightness from comets and active asteroids in the Solar System. Aims. We describe a numerical code, available to interested users, capable of generating simulated images of dust tail brightness for comparison with observations,

Comet Tail Analyzer: A GUI Tool for Finson–Probstein Dust-tail Modeling

Research Notes of the AAS
Abstract I present Comet Tail Analyzer , an open-source Python graphical application for projecting Finson–Probstein syndyne and synchrone grids onto comet images. Operating as a forward-modeling tool, the software computes and overlays dust-particle loci on user-supplied ...

Comet Gas and Dust Dynamics Modeling [PDF]

, 2010
This software models the gas and dust dynamics of comet coma (the head region of a comet) in order to support the Microwave Instrument for Rosetta Orbiter (MIRO) project. MIRO will study the evolution of the comet 67P/Churyumov-Gerasimenko's coma system.

Comet 67P/Churyumov-Gerasimenko sheds dust coat accumulated over the past four years [PDF]

, 2015
International audienceComets are composed of dust and frozen gases. The ices are mixed with the refractory material either as an icy conglomerate1, or as an aggregate of pre-solar grains (grains that existed prior to the formation of the Solar System ...

A Tale of Two Tails

, 2009
This paper outlines the key difference between ion tails and dust tails. It explains why meteor showers are observed when the Earth passes close to the orbit of a comet by examining the distribution of fragments within the dust tail in term of their ...

The wind-sock theory of comet tails [PDF]

, 1976
A method is reported for calculating the shapes of ionic comet tails that use the magnetic field along the tail to channel the tail plasma. The local momentum field in the solar wind determines magnetic field line locations along the tail.
