Lille Observatory Workshop 27-30 September 2011

   

DYNAMICS AND FORMATION OF THE OORT CLOUD



The existence of a huge cloud of comets surrounding the solar system has been first conjectured by Opik in 1932. Later, in 1950, Oort showed that comets from this region may become observable, explaining the origin of long period comets.

However, modern simulations of the transport of comets from the Oort cloud to the inner solar system show that the cloud should contain a number of comets as large as 1011 in order to explain the flux of observed long period comets.
Such a large number is very difficult to obtain via realistic modelling of the solar system formation and usually lead to contradicting results.

Recently, some new ideas about both the Oort cloud formations and the dynamics of Oort cloud comets come out. The present workshop is aimed precisely to review some of the more recent and popular ideas and to confront them.
