WHFast512: A symplectic N-body integrator for planetary systems optimized with AVX512 instructions
Pejvak Javaheri, Hanno Rein, Dan Tamayo
We describe the implementation of the symplectic N-body integrator WHFast512 using Single Instruction Multiple Data (SIMD) parallelism and 512-bit Advanced Vector Extensions (AVX51…
On the Degree of Dynamical Packing in the Kepler Multi-planet Systems
Alysa Obertas, Daniel Tamayo, Norm Murray
Current planet formation theories rely on initially compact orbital configurations undergoing a (possibly extended) phase of giant impacts following the dispersal of the dissipativ…
ASSIST: An Ephemeris-Quality Test Particle Integrator
Matthew J. Holman, Arya Akmal, Davide Farnocchia +5
We introduce ASSIST, a software package for ephemeris-quality integrations of test particles. ASSIST is an extension of the REBOUND framework and makes use of its IAS15 integrator…
Self-Consistent Spin, Tidal and Dynamical Equations of Motion in the REBOUNDx Framework
Tiger Lu, Hanno Rein, Daniel Tamayo +4
We have introduced self-consistent spin, tidal and dynamical equations of motion into REBOUNDx, a library of additional effects for the popular N-body integrator REBOUND. The equat…
The Yarkovsky effect in REBOUNDx
Noah Ferich, Stanley A. Baronett, Daniel Tamayo +1
To more thoroughly study the effects of radiative forces on the orbits of small, astronomical bodies, we introduce the Yarkovsky effect into REBOUNDx, an extensional library for th…
celmech: A Python package for celestial mechanics
Sam Hadden, Daniel Tamayo
We present celmech, an open-source Python package designed to facilitate a wide variety of celestial mechanics calculations. The package allows users to formulate and integrate equ…
Stability Constrained Characterization of the 23 Myr-old V1298 Tau System: Do Young Planets Form in Mean Motion Resonance Chains?
Roberto Tejada Arevalo, Daniel Tamayo, Miles Cranmer
A leading theoretical expectation for the final stages of planet formation is that disk migration should naturally drive orbits into chains of mean motion resonances (MMRs). In ord…
A Criterion for the Onset of Chaos in Compact, Eccentric Multiplanet Systems
Daniel Tamayo, Norman Murray, Scott Tremaine +1
We derive a semi-analytic criterion for the presence of chaos in compact, eccentric multiplanet systems. Beyond a minimum semimajor-axis separation, below which the dynamics are ch…
TIC 454140642: A Compact, Coplanar, Quadruple-lined Quadruple Star System Consisting of Two Eclipsing Binaries
Veselin B. Kostov, Brian P. Powell, Guillermo Torres +30
We report the discovery of a compact, coplanar, quadruply-lined, eclipsing quadruple star system from TESS data, TIC 454140642, also known as TYC 0074-01254-1. The target was first…
How Close are Compact Multi-Planet Systems to the Stability Limit?
Samuel W. Yee, Daniel Tamayo, Samuel Hadden +1
Transit surveys have revealed a significant population of compact multi-planet systems, containing several sub-Neptune-mass planets on close-in, tightly-packed orbits. These system…
A Bayesian neural network predicts the dissolution of compact planetary systems
Miles Cranmer, Daniel Tamayo, Hanno Rein +5
Despite over three hundred years of effort, no solutions exist for predicting when a general planetary configuration will become unstable. We introduce a deep learning architecture…
Stellar Evolution and Tidal Dissipation in REBOUNDx
Stanley A. Baronett, Noah Ferich, Daniel Tamayo +1
To study the post-main sequence evolution of the Solar system and exoplanetary systems more accurately and efficiently, we introduce two new features to REBOUNDx, an extended libra…
Revisiting the Architecture of the KOI-89 System
Kento Masuda, Daniel Tamayo
While high stellar obliquities observed in exoplanetary systems may be attributed to processes that tilt the planetary orbits, it is also possible that they reflect misalignments b…
Stability Constrained Characterization of Multiplanet Systems
Daniel Tamayo, Christian Gilbertson, Daniel Foreman-Mackey
Many discovered multiplanet systems are tightly packed. This implies that wide parameter ranges in masses and orbital elements can be dynamically unstable and ruled out. We present…
Predicting the long-term stability of compact multiplanet systems
Daniel Tamayo, Miles Cranmer, Samuel Hadden +11
We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compac…
Fundamental limits from chaos on instability time predictions in compact planetary systems
Naireen Hussain, Daniel Tamayo
Instabilities in compact planetary systems are generically driven by chaotic dynamics. This implies that an instability time measured through direct N-body integration is not exact…
Direct Imaging of Irregular Satellite Disks in Scattered Light
Loic Nassif-Lachapelle, Daniel Tamayo
Direct imaging surveys have found that long-period super-Jupiters are rare. By contrast, recent modeling of the widespread gaps in protoplanetary disks revealed by ALMA suggests an…
REBOUNDx: A Library for Adding Conservative and Dissipative Forces to Otherwise Symplectic N-body Integrations
Daniel Tamayo, Hanno Rein, Pengshuai Shi +1
Symplectic methods, in particular the Wisdom-Holman map, have revolutionized our ability to model the long-term, conservative dynamics of planetary systems. However, many astrophys…
