Abstract
One of the central questions to be addressed by the NASA Psyche mission is the composition and origin of the asteroid (16) Psyche. In preparation of the mission's planned arrival in 2029, in this work we explore how different internal structures may be expressed on (16) Psyche. We model the core size and shape that may exist at (16) Psyche given currently available constraints. We find that if Psyche has compositional layering, then tectonic features accommodating large amounts of compression from pore closure and a freezing core may be present. We also find that because of (16) Psyche's elongated shape and fast rotation, it is important to properly reference the elevations to the geoid (i.e., the accelerations a particle will feel) when interpreting possible mass wasting effects.
期刊介绍：
The Journal of Geophysical Research Planets is dedicated to the publication of new and original research in the broad field of planetary science. Manuscripts concerning planetary geology, geophysics, geochemistry, atmospheres, and dynamics are appropriate for the journal when they increase knowledge about the processes that affect Solar System objects. Manuscripts concerning other planetary systems, exoplanets or Earth are welcome when presented in a comparative planetology perspective. Studies in the field of astrobiology will be considered when they have immediate consequences for the interpretation of planetary data. JGR: Planets does not publish manuscripts that deal with future missions and instrumentation, nor those that are primarily of an engineering interest. Instrument, calibration or data processing papers may be appropriate for the journal, but only when accompanied by scientific analysis and interpretation that increases understanding of the studied object. A manuscript that describes a new method or technique would be acceptable for JGR: Planets if it contained new and relevant scientific results obtained using the method. Review articles are generally not appropriate for JGR: Planets, but they may be considered if they form an integral part of a special issue.
