Identifiable Uniqueness of Impulsively Forced, Inert, and Stabilized Body Trajectories
Bo Pieter Johannes Andrée
An unusual object in the sky raises two related questions: what kind of object it is and what physical process drives its motion. Departures from a gravity-only trajectory can prov…
Trajectory Stability and Signature Diagnostics for Comet-Based Interstellar Navigation
Bo Pieter Johannes Andrée
Interstellar objects (ISOs) motivate a coupled mission-design and inference question relevant to spacecraft dynamics and control in extreme environments: if volatile-rich, rotating…
A Minimal Four-Thruster System for Comet-Based Interstellar Navigation
Bo Pieter Johannes Andrée
Interstellar comets arrive with key ingredients for deep-space platforms already in place: volatile inventories convertible to propellant, natural rotation providing continuous att…
Range-Based Volatility Estimators for Monitoring Market Stress: Evidence from Local Food Price Data
Bo Pieter Johannes Andrée
Range-based volatility estimators are widely used in financial econometrics to quantify risk and market stress, yet their application to local commodity markets remains limited. Th…
