This commit introduces a new Exosphere class in the flekspy.util module for modeling neutral density profiles in planetary exospheres.

The Exosphere class supports multiple profile types, including exponential, power-law, and the Chamberlain model. It is initialized with physical parameters such as number density, scale height, temperature, and exobase radius.

A plot_neutral_profile method is included to visualize the neutral density as a function of altitude, providing a convenient way to inspect the model's output.

Unit tests have been added to ensure the correctness of the implementation, covering all density profiles and the plotting functionality.

Summary of Changes

Hello @henry2004y, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the flekspy.util module by integrating a robust Exosphere model. This new capability allows for the simulation and analysis of neutral density profiles in planetary exospheres, offering flexibility through support for multiple physical models. The inclusion of a plotting utility simplifies data interpretation, and thorough unit testing guarantees the reliability of the new features.

Highlights

  • New Exosphere Model: Introduced a new Exosphere class within flekspy.util for modeling neutral density profiles in planetary exospheres.
  • Multiple Density Profiles: The Exosphere class supports various neutral density profile types, including 'exponential', 'power_law', and 'chamberlain'.
  • Visualization Utility: A plot_neutral_profile method has been added to visualize the neutral density as a function of altitude, aiding in model inspection.
  • Comprehensive Unit Tests: New unit tests have been implemented to ensure the correctness of the Exosphere class, covering all density profile calculations and the plotting functionality.

Code Review

This pull request introduces a new Exosphere class for modeling neutral density profiles, along with corresponding unit tests. The implementation is well-structured and the tests cover the main functionality. My review includes several suggestions to improve the code's robustness, clarity, and maintainability:

  • In flekspy.util.exosphere.py:

    • Removing an unused parameter from the __init__ method.
    • Clarifying a docstring to prevent misuse.
    • Improving the class design by removing unnecessary instance attributes.
    • Using typing.Literal to make the neutral_profile parameter more robust.
    • Adding type hints to a method signature for better static analysis.
  • In tests/test_exosphere.py:

    • Refactoring tests using pytest.mark.parametrize to reduce code duplication.
    • Decoupling tests from implementation details for more robust verification.

These changes will enhance the quality and usability of the new Exosphere model.

This commit introduces a new `Exosphere` class in the `flekspy.util` module for modeling neutral density profiles in planetary exospheres.

The `Exosphere` class supports multiple profile types, including exponential, power-law, and the Chamberlain model. It is initialized with physical parameters such as number density, scale height, temperature, and exobase radius. The `neutral_profile` parameter uses `typing.Literal` for improved type safety.

A `plot_neutral_profile` method is included to visualize the neutral density as a function of altitude, providing a convenient way to inspect the model's output.

Unit tests have been added to ensure the correctness of the implementation, covering all density profiles and the plotting functionality. The tests have been refactored to use `pytest.mark.parametrize` for better readability and maintainability.
