VizieR Online Data Catalog: Resonance sticking in the population of scattering TNOs (Yu+, 2018)
Abstract
To determine the orbital distribution of currently resonant objects that may be attributed to transient sticking from today's population of scattering trans-Neptunian objects (TNOs), we perform a series of numerical simulations. We use a model of the current scattering population (see Gladman et al. 2008ssbn.book...43G for a detailed definition of this population) for our initial conditions. Following Alexandersen et al. (2013Sci...341..994A) and Shankman et al. (2013ApJ...764L...2S), we use initial conditions from a scattering population simulated in Kaib et al. (2011Icar..215..491K), with inclinations adjusted to reflect a dynamically hotter initial disk of particles. We are interested in resonance sticking at all timescales, from 105 yr (a few libration periods for close-in resonances) to the age of the solar system. However, the total population of scattering TNOs has decayed over time. We thus restrict ourselves to 109 yr timescales and treat any remnant resonant TNOs that were "transiently" stuck more than 1 Gyr ago as part of the primordial (i.e., not modeled) population.
