NAME

  Particles_sinkAdvanceParticles

SYNOPSIS

  call Particles_sinkAdvanceParticles(real, INTENT(in) :: dr_dt)

DESCRIPTION

  Updates sink particle postions and velocities based on gravitational accelerations,
  using Leapfrog or Euler, depending on the user's choice. There is also a special
  implementation of Leapfrog for cosmological simulations.
  This routine performs subcycling on sink-sink interactions, in case of very close
  encounters and highly eccentric orbits.

ARGUMENTS

   dr_dt - the current time step
