Data for the PSJ manuscript "Interrogating 16 Psyche's interior with rotational dynamics and gravity field"
收藏资源简介:
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." The archive includes three simulation ensembles: (1) a homogeneous reference model with the nominal initial spin-pole orientation, (2) simulations with varying principal moments of inertia and a fixed initial spin pole and (3) models with varying principal moments of inertia and varying initial spin-pole orientations. Each archive file contains time series of the spin pole and orbit normal right ascension and declination in the J2000 reference frame, together with the principal moments of inertia, dynamical flattening and obliquity. The orbit normal is derived from the instantaneous orbital angular momentum vector. 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, 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.
