Data for "Interrogating 16 Psyche's interior with rotational dynamics and gravity field"

This dataset contains numerical simulations of the rotational dynamics of asteroid 16 Psyche used in the study "Interrogating 16 Psyche's Interior with Rotational Dynamics and Gravity Field," which is accepted to the PSJ. The archive includes four simulation ensembles: (1) a homogeneous reference model with the nominal initial spin-pole orientation, integrated forward in time for 100 y; (2) simulations with varying principal moments of inertia and a fixed initial spin pole, integrated forward in time for 100 y; (3) models with varying principal moments of inertia and varying initial spin-pole orientations, integrated forward in time for 100 y; (4) models with varying principal moments of inertia and varying initial spin-pole orientations integrated backward in time for 10 My. Each archive file contains time series of the spin pole, orbit normal right ascension and declination in the J2000 reference frame, position and velocity of the asteroid, together with the principal moments of inertia, dynamical flattening and obliquity. The data are stored in a Matlab structure named workspace. For each simulation, the archive provides the time vector, spin-axis coordinates, orbit-normal coordinates, position and velocity, normalized principal moments of inertia, dynamical flattening and spin obliquity. Rows of the data arrays correspond to individual simulations, while columns correspond to time samples. The dataset is intended to support analyses of how Psyche's rotational evolution depends on its internal mass distribution.See full description in the provided PDF document.
