J/AJ/167/271 List of 213 planetary systems architectures (Volk+, 2024) ================================================================================ Differences between Stable and Unstable Architectures of Compact Planetary Systems. Volk K., Malhotra R. =2024AJ....167..271V ================================================================================ ADC_Keywords: Exoplanets; Stars, double and multiple Keywords: Exoplanets ; Exoplanet dynamics ; Exoplanet systems ; Orbital evolution Abstract: We present a stability analysis of a large set of simulated planetary systems of three or more planets based on architectures of multiplanet systems discovered by Kepler and K2. We propagated 21400 simulated planetary systems up to 5 billion orbits of the innermost planet; approximately 13% of these simulations ended in a planet-planet collision within that time span. We examined trends in dynamical stability based on dynamical spacings, orbital period ratios, and mass ratios of nearest-neighbor planets as well as the system-wide planet mass distribution and the spectral fraction describing the system's short-term evolution. We find that instability is more likely in planetary systems with adjacent planet pairs that have period ratios less than 2 and in systems of greater variance of planet masses. Systems with planet pairs at very small dynamical spacings (less than ~10-12 mutual Hill radii) are also prone to instabilities, but instabilities also occur at much larger planetary separations. We find that a large spectral fraction (calculated from short integrations) is a reasonable predictor of longer-term dynamical instability; systems that have a large number of Fourier components in their eccentricity vectors are prone to secular chaos and subsequent eccentricity growth and instabilities.

This file table2.dat 380 213 *List of system architectures in this work -------------------------------------------------------------------------------- Note on table2.dat: In all cases except one (Kepler-271; see notes for that system), the orbital periods for all planets were taken to be the default value and uncertainties in the Exoplanet Archive composite planet table (http://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/ nph-tblView?app=ExoTbls&config=PSCompPars). In almost all cases, the orbital periods for each planet from different lightcurve analyses agree within uncertainties. Unless otherwise indicated in the notes column, inclinations and eccentricities for all planets were assigned from the Rayleigh distributions described in Section 2. MR masses are generated from the statistical mass-radius relationship from Wolfgang et al. (2016) for planets with radii of 4R_Earth_ or smaller. For planets exceeding that size limit, we either use a TTV/RV mass measurement (indicated in the notes column) or we use the mass and uncertainty given in the Exoplanet Archive Composite data table, which is based on the mass-radius relationship from Chen & Kipping (2017), see http://exoplanetarchive.ipac.caltech.edu/docs/composite_calc.html. For systems where we used this mass estimate, the specific planet is indicated in the notes column as coming from an alternate MR relationship. -------------------------------------------------------------------------------- See also: J/ApJS/197/8 : Keplers candidate multiple transiting planet (Lissauer+, 2011) J/ApJ/750/114 : Kepler TTVs.

In these cases the system has a second entry in the table/simulation set with the additional planet included. (3 occurrences) Note (2): MMR as follows: 0 = no planets are near strong MMRs (mean motion resonances); 1 = one or more pair of planets is in or very close to a strong MMR; 2 = one or more pair of planets is close enough to a strong MMR that resonant interactions cannot entirely be ruled out (especially if simulated planets evolve to large eccentricities).
