Scientific paper

At least nine exoplanetary systems contain pairs of planets that appear to be close to a low-order mean motion resonance. Amongst these systems, the most common period ratio is 2:1, but 3:2 and 3:1 also appear. Using the FARGO hydro code, we investigate how planetary masses and disk properties, including viscosity and surface density, influence the migration of pairs of planets in a circumstellar disk and the resonant configuration that they are most likely to enter. Finally, we discuss the extent to which HD 82943's period ratio reflects the properties of the circumstellar disk from which it formed.
