PROFILE
Adam Brcek
Adam Brcek developed and maintained advanced stellar evolution modeling features for the TeamCOMPAS/COMPAS repository, focusing on core mass prescription frameworks and mass loss calculations. He refactored and extended C++ code to implement new physical prescriptions, such as the BRCEK and HURLEY models, and improved numerical robustness with utilities for floating-point comparison. Adam addressed configuration consistency, documentation clarity, and merge conflict resolution, ensuring maintainability and reproducibility. His work included targeted bug fixes, enhancements to binary evolution and chemically homogeneous star modeling, and careful integration of scientific algorithms. The depth of his contributions strengthened both the physical fidelity and reliability of the codebase.

Dec 1, 2025December 2025 monthly work summary for TeamCOMPAS/COMPAS. Focused on improving the accuracy of mass loss modeling and clarifying scope of scaling across stellar populations. Key features delivered: CHE-specific Mass Loss Scaling Enhancement, applying mass loss scaling only to chemically homogeneous evolving (CHE) stars based on surface helium abundance. Major bugs fixed: Mass Loss Scaling Default Fix in COMPAS, correcting the default value for mass loss scaling, fixing mass loss behavior for main sequence stars, and incrementing the version number. Overall impact: improved physical fidelity of mass loss predictions, reduced risk of misconfiguration in user workflows, and a clean, versioned release to support reproducibility and adoption. Technologies/skills demonstrated: domain-driven feature development in stellar evolution modeling, precise patch commits and git-based versioning, thorough documentation updates for user guidance, and clear commit messages that support traceability.

Oct 1, 2025Month: 2025-10 — TeamCOMPAS/COMPAS delivered a major feature: rename of the MS core mass prescription option from ZERO to HURLEY across configuration files, documentation, and source code, aligning with Hurley et al. (2000). ZERO is deprecated in favor of HURLEY to ensure consistency and reduce user confusion. No major bugs fixed this month. Impact: improved maintainability, clearer configuration semantics, and a foundation for future deprecation and analytics consistency. Technologies demonstrated: configuration management, cross-file refactoring, documentation alignment, and version-control discipline.

Jun 1, 2025June 2025 (2025-06) — TeamCOMPAS/COMPAS: Delivered substantive feature improvements and targeted bug fixes with a focus on physical fidelity and cross-model consistency. BRCEK model improvements and maintenance enhanced core mass prescriptions for CH stars and MS mergers, including refinements to MS core mass calculation and related maintenance tasks; solar metallicity handling was standardized across models with consolidated definitions and helper utilities. Hydrogen mass calculation corrections for binary mergers fixed hydrogen accounting across regions to ensure final masses align with surface abundances, complemented by typo fixes and documentation updates. Overall, contributions improve modeling reliability, traceability, and maintainability, supporting robust scientific analyses and clearer collaboration across the modeling team.
