About mesalab pipeline

⚠️NOTE: This project is currently under active development. Features and APIs may change, and new functionalities are continuously being added.

The Python package mesalab is designed for processing and analyzing stellar evolution simulations performed with MESA (Modules for Experiments in Stellar Astrophysics). It is developed to efficiently handle large grids of simulations, such as those where stellar mass (M) and metallicity (Z) are systematically varied.

The primary goal of this pipeline is to take your MESA outputs and automatically:

1. Analyze each simulation within your grid.
2. Identify if the star enters the blue loop phase and crosses the instability strip.
3. Based on these findings, prepare GYRE input files and run the corresponding pulsation simulations.

Building from Source (Recommended for Developers)

For scientific packages with complex dependencies like mesalab, we highly recommend using a conda environment to build from source. This ensures all binary dependencies are handled correctly, avoiding common compiler errors.

Step 1: Set up the conda environment (Python version between 3.9 and 3.11) Create a dedicated environment with all the necessary scientific packages. The conda-forge channel is required for some dependencies.

$ conda create --name mesalab_env python=3.9
$ conda activate mesalab_env
$ conda install -c conda-forge numpy pandas matplotlib scipy pyyaml tqdm numba swifter dask pyarrow h5py astropy

Step 2: Install mesalab from source Clone the repository and install the project in "editable" mode.

$ git clone https://github.com/konkolyseismolab/mesalab
$ cd mesalab
$ pip install -e .

Usage

To get started, you'll need to prepare a configuration file (e.g., config.yaml) that specifies your MESA input directories, output locations, and analysis preferences.

You can run mesalab by providing your configuration file:

$ mesalab --config myconfig.yaml

For a full list of command-line arguments and their descriptions, use the help command:

$ mesalab --help

For more detailed information on configuration options, command-line arguments, and advanced usage, please consult the official mesalab documentation on Read the Docs.
