"Our new paper is on the #arXiv / @OJ_Astro today! We derive a new timestepping criterion for #Nbody simulations with adaptive integrators such as IAS15. We show that our new criterion always resolves all physical timescales in Keplerian orbits, regardless of eccentricity. It's also much less likely to be affected by finite floating point precision which previously often led to slow or stalled simulations. The new criterion is now the default for IAS15 in REBOUND.
