Ejection of rocky and icy material from binary star systems: Implications for the origin and composition of 1I/`Oumuamua
Alan P. Jackson, Daniel Tamayo, Noah Hammond +2
In single star systems like our own Solar system, comets dominate the mass budget of bodies that are ejected into interstellar space, since they form further away and are less tigh…
Resonant structure, formation and stability of the planetary system HD155358
Ari Silburt, Hanno Rein
Two Jovian-sized planets are orbiting the star HD155358 near exact mean motion resonance (MMR) commensurability. In this work we re-analyze the radial velocity (RV) data previously…
Convergent Migration Renders TRAPPIST-1 Long-lived
Daniel Tamayo, Hanno Rein, Cristobal Petrovich +1
TRAPPIST-1 is a late M-dwarf orbited by seven Earth-sized planets with orbital period ratios near a chain of mean motion resonances. Due to uncertain system parameters, most orbita…
JANUS: A bit-wise reversible integrator for N-body dynamics
Hanno Rein, Daniel Tamayo
Hamiltonian systems such as the gravitational N-body problem have time-reversal symmetry. However, all numerical N-body integration schemes, including symplectic ones, respect this…
Connecting HL Tau to the Observed Exoplanet Sample
Christopher Simbulan, Daniel Tamayo, Cristobal Petrovich +2
The Atacama Large Millimeter/submilimeter Array (ALMA) recently revealed a set of nearly concentric gaps in the protoplanetary disk surrounding the young star HL Tau. If these are…
A new paradigm for reproducing and analyzing N-body simulations of planetary systems
Hanno Rein, Daniel Tamayo
The reproducibility of experiments is one of the main principles of the scientific method. However, numerical N-body experiments, especially those of planetary systems, are current…
