Birth cluster simulations of planetary systems with multiple super-Earths: initial conditions for white dwarf pollution drivers

We provide the output parameters from our planetary system simulations around white dwarf main-sequence progenitors (1.5, 2.0 and 2.5 solar mass stars) embedded in a birth star cluster containing 8,000 stars. The data can serve the community as initial conditions for subsequent evolution simulations, e.g. to further investigate the role of eccentric planets in the pollution of white dwarfs. The planetary systems, consisting solely of super-Earths with 0.01 Jovian masses, were started in three different orbital configurations. The 3P model contains 3 planets with initial semimajor axes between 2.00 and 18.63 AU. We also simulated two 7-planet system models with different orbital spacing. The 7PC model represents a compact planetary system with 7 planets between 2.00 and 18.63 AU. The 7PW model represents a wide planetary system with 7 planets between 2.00 and 56.87 AU. The three planetary system models were distributed around 193 stars with 1.5 solar masses, around 114 stars with 2.0 solar masses and around 101 stars with 2.5 solar masses, and numerically integrated for 100 Myr considering the gravitational forces from the neighbouring stars in the star cluster.
