PROFILE
Reinhold Willcox
Reinhold Willcox contributed to the TeamCOMPAS/COMPAS repository by developing and refining astrophysics simulation features focused on binary star evolution and supernova modeling. He enhanced simulation outputs by adding detailed velocity and angular momentum vectors, standardized velocity component naming, and improved data logging for downstream analytics. Using C++ and Python, Reinhold implemented CI-friendly plotting, robust configuration management, and documentation updates to support reproducibility and collaboration. He addressed critical bugs in physics calculations, such as division-by-zero in Euler angle computations and Python boolean literal handling, demonstrating careful attention to reliability and correctness. His work reflects depth in numerical methods and code maintainability.

Jun 1, 2025June 2025 monthly summary for TeamCOMPAS/COMPAS: Implemented per-component velocity logging and standardized velocity component naming across the codebase and documentation. Introduced per-component velocity LogTypedefs and ensured outputs expose velocity components X, Y, Z (initially SPEED_X/Y/Z, then VELOCITY_X/Y/Z). Updated outputs, typedefs, and docs; committed changelog and documentation updates to reflect the new naming and logging capabilities. This work enhances observability, traceability, and consistency, enabling improved debugging and downstream analytics.

Mar 1, 2025March 2025 monthly summary for TeamCOMPAS/COMPAS focusing on feature delivery and technical accomplishments. Implemented enhanced supernova (SN) output to include orbital angular momentum and systemic velocity vectors, expanding the data returned per SN event. Updated the BINARY_PROPERTY enum, labels, and property details to support the new vector components. Added new output options for characterizing binary orientation post-supernova. Documentation and release notes updated to reflect the changes. All changes support richer physics diagnostics and improved downstream analyses for natal kicks, angular momentum distribution, and system velocities.
