A collaborative project to catalog and analyze post-mass transfer binary systems.
This project aims to provide a comprehensive catalog and analysis of post-mass transfer binary systems, including their key properties and observational data. The data is structured for easy analysis and reproducibility, supporting the astrophysics community in understanding binary evolution.
Repository link: binary-observations/post_mt_catalog
You can download the catalog in JSON format here.
All systems are stored in a json dictionary with at least the following columns (with key quantities as [err-, value, err+] triplets):
System Name, RA, Dec, Period, Eccentricity, M1, M1_sin3i, M2, M2_sin3i, q, Mass Function, Type1, Type2, Detection Method, Reference, NotesExample entry:
{
"System Name": "Example system",
"RA": [0.005, 150.025, 0.005],
"Dec": [0.004, -45.123, 0.004],
"Period": [0.2, 12.5, 0.3],
"Eccentricity": [0.02, 0.30, 0.03],
"M1": [0.5, 5.0, 0.5],
...
}Missing values are represented as np.nan. Lower/upper limits are handled using the M1_sin3i and M2_sin3i columns.
Do you think a post-mass transfer system is missing from the catalog? Double check if your system already exists in the catalog (by name/ID and by position). If it is not in the catalog, please submit the missing-system proposal. Thanks for contributing!
Processed tables and data products are available in the result_tables/ directory. Each file contains results for different post-mass transfer systems. See the project repository for details.
The interactive plots are generated using the Plotly library. You can find the code for the plots in the plots/ directory.
Try clicking the legend to toggle different classes on/off.
Have fun exploring the data below!
