Data Supporting "A Stellar Role Reversal: Multiple Features in the Mass and Mass Ratio Distributions of Merging Binary Black Holes from Stable Mass Transfer"

Résumé fourni par la source

This data release includes all BBH merger data and code necessary to recreate figures from A Stellar Role Reversal: Multiple Features in the Mass and Mass Ratio Distributions of Merging Binary Black Holes from Stable Mass Transfer. This data release does not include the intermediate COSMIC outputs, which include the full binary evolution history of each BBH. To rerun the binaries, run the code below with COSMIC version 4.1.0. The total runtime for each beta variation is ~10 CPU hours. import pandas as pd import numpy as np from cosmic.sample.initialbinarytable import InitialBinaryTable from cosmic.evolve import Evolve # Load data data_path = 'beta_1.0.h5' params_path = 'beta_1.0_params.ini' init_cond = pd.read_hdf(data_path, key='all_bbh_mt_df')[['mass_1_zams', 'mass_2_zams', 'porb_zams', 'ecc_zams', 'met_cosmic']] # Set up COSMIC readable table initial_binary_table = InitialBinaryTable.InitialBinaries(m1=init_cond.mass_1_zams, m2=init_cond.mass_2_zams, porb=init_cond.porb_zams, ecc=init_cond.ecc_zams, tphysf=np.full(len(init_cond), 13700.0), metallicity=init_cond.met_cosmic, kstar1=np.full(len(init_cond), 1), kstar2=np.full(len(init_cond), 1)) # Evolve binaries bpp, bcm, initC, kick_info = Evolve.evolve(initialbinarytable=initial_binary_table, params=params_path, progress=True)
