DESCRIPTION:Currently\, there are approximately 20 circumbinary planetary s
 ystem detected. Most of them have only one single planet. Binary systems a
 re great scenarios to test planet formation theories and to study the evol
 ution of the planets\, because the presence of the secondary companion inc
 rease the dynamic complexity. Several authors showed that planets can not 
 be formed close to the binary star system because the relative velocities 
 of the planetesimals\, precursors of future planets\, are high enough to c
 ause erosion\, fragmentation\, etc\, between them. Hydrodynamic simulation
 s suggest that planets could have formed at farther distances\, and in its
  interaction with the gas the planet migrates to the inner edge of the dis
 k (Pierens &amp\; Nelson 2007\, 2008\, Kley &amp\; Haguiguipour 2014\, 201
 5). In the presence of two planets in interaction with the gas disk\, reso
 nance captures between the planets may occur depending on the considered p
 lanetary mass configuration of the system\, leading\, in some cases\, to t
 he ejection of one of the planets (Pierens &amp\; Nelson 2007).\nThe main 
 objective of my PhD project is to study the dynamical evolution of planets
  in several resonances around binary star systems after the dissipation of
  the gas. In this presentation I will present the state of the art\, some 
 results obtained so far and the next steps of the project. https://astrono
