Lille Observatory Workshop 27-30 September 2011
DYNAMICS AND FORMATION OF THE OORT CLOUD
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.
Location and transport
workshop will take place at Lille Observatory, 1 impasse de
l'observatoire, 59 000 Lille, France (longitude 3°4'15"
E, latitude 50°36'57" N, altitude 32m).
To reach Lille
there is many fast trains from "Paris Gare du Nord" or "Paris
Roissy-Charles de Gaulles Airport" (about one hour in both cases), from
"London St Pancras" (about 1h30 hours) and from "Bruxelles-Midi" (about
30 mn) . More information and ticket reservations here.
