Scientific paper

We have carried out three-dimensional hydrodynamical modeling of the formation of planets through the merging of a binary system comprised of low-mass (˜0.5 1 M&sun;) stars in the stage of contracting towards the main sequence. Under certain conditions, the disruption of the more massive component results in the formation of an expanding disk and extended arm. The fragmentation of this arm leads to the formation of planetary-mass clouds (<5 M J where M J is the mass of Jupiter), whose orbits can have semimajor axes of 0.4 to 5 AU and substantial (˜0.5) eccentricities.
